Spiral steel pipe has a very important role in our life, the following is based on the heat treatment process of spiral steel pipe, introducing the common defects of each process.

The quality control of the straight seam welded pipe is the only way to safely carry out the production operation, and it is also an inevitable element to protect the personal safety of the operator. Application areas are mainly in large-span network frame project, building steel structure project, electric power and ultra-high voltage power transmission and distribution projects, mechanical engineering, cross-sea bridges, bridges, (railway station, airport, stadium steel structure project), municipal pipeline network, foundation piling, water and gas pipelines and highway construction and other ancillary facilities.

LSAW steel pipe is a kind of welded steel pipe. Steel pipe parallel to the longitudinal direction of the steel pipe. The hot rolled steel coil is formed by forming machine, and then the said coil is converted into a cylinder and welded by using high frequency current skin effect and proximity effect or arc combustion under the flux layer, so that the edge of the pipe billet is heated, melted, fused and cooled to form under a certain extrusion pressure, correct, petroleum, metallurgy, construction, coal mine, port, machinery, and other industries are widely used in the transportation of oil and gas, low-pressure water and gas transportation, mine fluid transportation , belt conveyor, automobile drive shaft and other industries.

There are many kinds of Q235B LSAW welded pipe quality inspection methods, among which the physical method is also the most commonly used inspection method, physical inspection is the use of some physical phenomena for determination or inspection methods. Material or Q235B LSAW welded pipe internal defects inspection, are generally used non-destructive flaw detection methods. The current nondestructive flaw detection has magnetic flaw detection, ultrasonic flaw detection, ray detection, penetration flaw detection, etc..

How to control the quality of spiral steel pipe? The piercing temperature of steel billet varies depending on the raw material. The temperature of most hot expanded welded pipes is about 1200℃, and slightly lower when the carbon content and other alloying elements are higher.

Stainless steel seamless pipe welding and polishing technology is a widely used technology for stainless steel pipe welding and surface treatment. Stainless steel seamless pipe welding and polishing technology and products related knowledge and application. I. Stainless steel seamless pipe welding 1, seamless stainless steel pipe welding process

Stainless steel welded pipe processing process is prone to cause certain changes to the internal or external stainless steel welded pipe, Centerway Steel as a 13 years of stainless steel welded pipe professional manufacturers, for you to summarize some of the knowledge about stainless steel welded pipe processing for reference:

Stainless steel stainless steel welded pipe manufacturers steel plate ultrasonic flaw detection: used to produce large diameter self-seam submerged arc welded steel pipe steel plate into the production line, the first full plate ultrasonic inspection; both sides of the steel plate milling: through the milling machine on both edges of the steel plate double-sided milling, so that it arrives at the required plate width, edge parallelism and bevel shape.

Stainless steel welded pipe made to order quality inspection methods have a variety of methods, including physical methods are also commonly used inspection methods, physical inspection is the use of some physical phenomena for determination or inspection methods. Material or stainless steel welded pipe internal defects inspection, generally using non-destructive flaw detection methods. The current nondestructive flaw detection has magnetic flaw detection, ultrasonic flaw detection, ray detection, penetration detection, etc..

Nowadays the application of stainless steel welded pipe is very wide, but in the process of using stainless steel welded pipe there will be rust, rusty straight seam welded steel pipe is going to affect its normal use, so the stainless steel welded pipe found on the rust situation needs to be cleaned up in a timely manner, then today to give you several ways to clean the straight seam welded steel pipe, you can learn about it:
