Stainless steel welded pipe, referred to as welded pipe, commonly used steel or steel strip after the unit and mold crimped forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety specifications, less equipment investment, but the general strength is lower than seamless steel pipe.

Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the progress of welding and inspection technology, the quality of welds continues to improve, and the variety specifications of welded steel pipes are increasing, and in more and more fields, especially in the heat exchange equipment with pipes, decorative pipes, medium and low pressure fluid pipes and other aspects of the replacement of seamless steel pipes.

First, the small-caliber stainless steel welded pipe is continuous online production, the thicker the wall thickness, the greater the investment in the unit and the melting equipment, the less economical and practical it is. The thinner the wall thickness, the lower the input-output ratio; Secondly, the process of the product determines its advantages and disadvantages. Generally, the welding steel pipe has high precision, uniform wall thickness, high external brightness inside the pipe (the surface brightness of the steel pipe determined by the surface grade of the steel plate), and can be arbitrarily measured. Therefore, it reflects its economy and aesthetics in high precision, medium and low pressure fluid applications.

According to the form of weld, it is divided into straight seam welded pipe and spiral welded pipe.

According to the use, it is divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-wall pipe, electric welded special shape pipe and spiral welded pipe

Product Application

Nickel alloy tube can be used in the High temperature components such as turbine blades, guide vanes, turbine disks, high pressure compressor disks,machine manufacturing and combustion chambers used in the manufacture of aviation, naval and industrial gas turbines.
