Features of stainless steel welded pipe
Stainless steel welded pipes are produced continuously online. The thicker the wall thickness, the greater the investment in the unit and welding equipment, and the less economical and practical it is. The thinner the wall thickness, the lower the input-output ratio. Second, the process of the product determines its advantages and disadvantages. Generally, the welded steel pipe has high precision, uniform wall thickness, and high brightness inside and outside the pipe (steel pipe determined by the surface grade of the steel plate Surface brightness), can be arbitrarily sized. Therefore, it embodies its economy and aesthetics in high-precision, low- and medium-pressure fluid applications.
First of all, in the forming process of stainless steel welded pipe, the steel plate is deformed uniformly, the residual stress is small, and the surface is not scratched. The processed stainless steel welded pipe has greater flexibility in the size range of diameter and wall thickness, especially in the production of high-grade thick-walled pipes, especially small and medium-diameter thick-walled pipes, which has advantages over other processes. And can satisfy users. The specification of stainless steel welded pipe is higher; using the internal and external welding (finishing) process before the first welding, it can be welded in a better position, and it is not prone to defects welding deviation and non-weld penetration defects, if the overall mechanical diameter is expanded, it can effectively improve stainless Dimensional accuracy of welded pipe, improve the stress distribution of stainless steel welded pipe, avoid damage caused by stress corrosion, and facilitate on-site welding construction; conduct 9 items of 100% quality inspection on stainless steel welded pipe, so that the entire process of stainless steel welded pipe production is monitored under effective detection Guaranteed product quality.
According to welding technology, it can be divided into automatic welding and manual welding. Automatic welding generally adopts submerged arc welding, plasma welding, and manual welding generally adopts argon arc welding.
According to the weld form, it is divided into straight seam welded pipe and spiral welded pipe.
It is divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen-blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automotive pipe, transformer pipe, electric welding thin wall Pipe, welded special-shaped pipe and spiral welded pipe
Pipes are widely used in water supply projects Petrochemical industry Chemical industry Power industry Agricultural irrigation City construction is one of the 20 key products developed in China.
