The scope of application of mechanical equipment is very wide, according to different needs, square tube machine also has different characteristics. So what's the difference between welded square tube and seamless square tube? Let's follow gzcomifo to understand it.

1. Square tube is a hollow square section steel square tube, also known as steel cold-formed section. It is a section steel with square section shape and size, which is made of hot or cold rolled strip or coil as the blank by cold bending and then by high frequency welding. In addition to wall thickness thickening, the corner size and edge straightness of square tube can reach or even exceed the level of resistance welding cold formed square tube.

2. Seamless square tube is a kind of long steel with hollow section and no joints around. The square tube machine has hollow section and is widely used as the pipeline for conveying fluid. Mainly used in liquid transportation, hydraulic support, mechanical structure, medium and low pressure, high pressure boiler pipe, heat exchange pipe, gas, oil and other industries.

HOW TO JUDGE THE QUALITY OF THE SQUARE TUBE MACHINE



source: gzcomifo; Time: 06/23/2020 Clicks: 142

As we all know, the quality of square tube machine is very important in the process of using. Let's talk about the good and bad quality of the square tube machine.



1. The fake square tube machine is easy to fold. Folding is a variety of fold lines formed on the surface of square tube, and this kind of defect often runs through the longitudinal direction of the whole product. The reason for folding is that the fake and inferior manufacturers pursue high efficiency, the reduction is too large, the ears are produced, the folding occurs in the next rolling, the folded products will crack after bending, and the strength of the steel will be greatly reduced.



2. The appearance of the fake square tube machine is often pockmarked. Pockmarked surface is a kind of irregular uneven defect on the surface of steel due to the serious wear of rolling groove. Because the fake square tube manufacturers want to pursue profits, and often the rolling groove exceeds the standard, it is necessary to select the equipment with better quality than the pipe welding machine.



3. There are two reasons for scab on the surface of fake square tube:

(1) The material of the fake square tube is uneven, and there are many impurities.

(2) It is easy to stick steel because of the poor guide equipment of the fake factory.

WHAT FACTORS ARE RELATED TO THE MANUFACTURING ACCURACY OF THE SQUARE TUBE MACHINE?

Stainless steel pipe is a kind of hollow long round steel, which is mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical appearance and other industrial transportation pipes and mechanical structural components. In addition, in bending. With the same torsional strength and light weight, it is also widely used to make mechanical parts and engineering structures of the square tube machine. It is also used to produce all kinds of weapons, barrels, shells, etc.



1. Concentricity

The manufacturing process of seamless tube makes a hole punched in stainless steel billet at 2200 ° F. at this high temperature, tool steel becomes soft and spiral from the air after stamping and drawing. In this way, the wall thickness of the pipe is uneven and the degree of bias is high. Therefore, ASTM allows the wall thickness difference of seamless welded pipe to be larger than that of welded pipe. Seamed tubes are made of accurate cold-rolled sheets (4-5 feet in width per roll), the maximum wall thickness difference of these cold-rolled sheets is generally 0.002 inch, and the steel plate is cut into a width of π D, in which D is the outer diameter of the tube. The wall thickness of seamed pipe is very small, and the wall thickness of the whole circumference is very uniform.



2. Welding function

Generally, there are certain differences in the chemical composition of the square tube machine between the sewn tube and the seamless tube. The steel composition of seamless pipe is only the basic requirement of ASTM. The steel produced with welded pipe contains a kind of welding melt which is easy to transfer heat during the welding process, so that the whole weld is fully penetrated. The square tube machine without the above chemical composition, such as seamless tube, will have various unstable factors in the welding process, which is not easy to be welded firmly and not fully penetrated.

THE MAINTENANCE SECRET OF WIND PIPE PRODUCTION LINE



source: gzcomifo; Time: 07/07/2020 Clicks: 128

The maintenance of the air duct production line is what all customers should pay attention to. Only by strengthening the maintenance of the air duct production line, can the machine operate and operate normally, ensure that the daily work of the air duct production line does not break down and stop, and ensure the daily high work efficiency and quality. Next, for you to introduce a few duct production line maintenance tips.



1. Cleaning of air duct production line

In the long-term work process of the air duct production line, a lot of materials and sundries will be left, so the air duct production line needs to be cleaned and maintained in time to avoid problems. Here are three cleaning methods for air duct production line:



(1) Gas flushing

&Nbsp; the hose with nozzle connected to the air duct can deliver compressed air to drive dust and dirt from the air duct to the vacuum collecting container, so as to remove dust and sundries.



(2) Vacuum suction

&Nbsp; this method requires a cleaning tool, called vacuum suction. The vacuum suction pipe adopts the hand-held type, and the brush can directly contact the inner wall of the pipe so as to achieve the purpose of cleaning the dirt in the pipe. But there is a requirement to adopt this method, that is, the manhole of air duct must be large enough. In addition, because the air duct can not form enough negative pressure conditions, it is likely that this cleaning method will leak some stains.



(3) Power wash

&The power of this way comes from pneumatic or electric. Under the action of pneumatic or electric power, the brush moves the dirt in the air duct, and then the dirt is transported to the vacuum collector by the way of gas washing. In this way, it should be noted that the surface of the insulation material is damaged during the cleaning process.
2. Routine maintenance of air duct production line

The air duct production line should also pay attention to the daily maintenance of the machine in daily use. The following points should be noted:

(1) Check the working condition of the air duct production line frequently, correct the problems found in time, and forbid the machine to run with faults to prevent the occurrence of safety accidents.

(2) Keep the appearance of air duct production line clean at all times. When it is not used for a long time, the surface shall be coated with anti rust grease.

(3) The operator shall operate correctly according to the specification, and understand and master the performance and operation method of the machine. It is strictly forbidden to operate by non professionals.



3. Regular maintenance of air duct production line

(1) Regularly add proper amount of lubricating oil to the driving teeth of the air duct production line, which can greatly reduce the wear degree of the machine in operation.

(2) Generally, the maintenance period of the air duct production line is half a year, and the machine and equipment are disassembled regularly for inspection and maintenance.

THE BASIS OF DISTINGUISHING QUALITY OF AIR PIPE PRODUCTION LINE



source: gzcomifo; Time: 07/14/2020 Clicks: 124

First of all, it is clear about the manufacturer of the air duct production line. The price of automatic production line is quite expensive, often several hundred thousand, so before we buy it, we must send someone to the factory for field investigation before we can make a decision. Manufacturers with complete equipment, large scale and standardized production are preferred.



Secondly, the process and equipment flow of the manufacturer of air duct production line is investigated. Only advanced equipment technology can produce high-quality and high-precision air duct, so the manufacturer with strong R & D technology and deep manufacturing experience is the first choice.



Moreover, we know whether the authority approval of the air duct production line manufacturer has passed the certification of ISO9001 and other relevant authorities. Only when the quality is guaranteed, can we ensure the quality of our products.



Finally, understand the sales situation of the manufacturer of the air duct production line. Good product reputation is naturally good. Only when the person who has bought and used it has said it is good, can it be used as one of the basis for judgment.



From the above points of attention, we can basically purchase a good quality air duct production line. Purchase water depth, but ensure quality is the bottom line, especially for machines with high quality and specification requirements.

FACTORS INFLUENCING THE PRICE OF WIND PIPE PRODUCTION LINE





source: gzcomifo; Time: 07/21/2020 Clicks: 130

There are many factors that affect the price of air duct production line:



1. Price of steel raw materials

The price fluctuation of steel raw materials is one of the important factors affecting the price of the air duct production line. Because of the instability of the raw materials just now, the price of the air duct production line will also fluctuate accordingly. According to the different amount of steel raw materials used in different air duct production lines, the price will also be adjusted with different ranges.



2. Transportation expenses

Due to different regions where the buyer is located, the air duct production line purchased by the buyer needs to be transported to the region where the buyer is located. Then the selling price of the air duct production line will be different for different transportation costs. If the buyer is close to the manufacturer, the price will generally be cheaper than the price of the air duct production line far away.



3. Control system

At the request of the buyer, different buyers may choose the control system of different air duct production lines. Generally speaking, the standard air duct production line system of the manufacturer can almost meet the production requirements of most buyers. Under the special requirements of the buyer, different air duct production line control systems may cause different prices of the air duct production lines and make adjustments.



4. Accessories and parts

The quality of the accessories and parts of the air duct production line will also have some impact on the price of the air duct production line. Some small-scale air duct production line manufacturers may choose some cheaper accessories and parts, so that the cost of the air duct production line will be reduced, and its sales price will also be cheaper for large-scale manufacturers.



5. others

There are other factors that affect the price of the air duct production line. For example, different cost of human resources, rent, price level, etc. all affect the sales price of the air duct production line.

The quality of the automatic air duct production line will have a great impact on the overall working effect and efficiency of the air duct. Today, the air duct manufacturer takes you into the quality inspection process of the automatic air duct production line, which you can't help but understand.



1. First, check whether the air pipeline manufacturer has passed the ISO9001 quality standard certification. Only through the certification of product quality can we get relative basic guarantee.



2. Secondly, understand the quality system and operation of the whole air duct production. Because the price of the automatic air duct production line is relatively high, the selection and purchase of it must be decided by a special person on the spot.



3. We also need to know the subcontractors of the whole air pipeline production enterprises. The manufacturer of the supporting products of the automatic air duct production line should also pass this certification.



4. Finally, it is necessary to investigate the technological equipment level of air pipeline production enterprises. Process equipment is an important material means to ensure product quality. If we do the above, we believe that the quality of the air duct production line can be better guaranteed.



In fact, the water depth of mechanical products procurement, no matter what the industry has stipulated, the product quality is actually a red line that can not be touched, especially for the full-automatic air duct production line, which has higher requirements on specifications and quality, in principle, as long as the above four points are done well, qualified air duct production line can be purchased when purchasing.
