ASTM A409 welded stainless steel pipe

ASTM A409 welded stainless steel pipe for Corrosive service

Product description:

Stainless steel welded pipe, or welded pipe, commonly used steel or steel belt after the machine set and mold crimping forming welded steel pipe.The production process of welded steel tube is simple, the production efficiency is high, the variety specification is much, the equipment investment is little, but the general strength is lower than seamless steel tube.

Since the 1930 , with the rapid development of high quality strip steel rolling production and the progress of welding and inspection technology, constantly improve the weld quality, increasing varieties of welded steel pipe specifications, and in the field of more and more especially in heat exchange equipment with low pressure fluid in pipe, decorative, pipe instead of seamless steel tube.

First, the small diameter stainless steel welded pipe is continuous on-line production, the thicker the wall, the greater the investment of the unit and the dissolving equipment, the less economic and practical it is.The thinner the wall, the lower the input-output ratio.Then determine its advantages and disadvantages of the product process, general high precision welded steel pipe, wall thickness uniformity, high brightness tube appearance (level determines the surface of the steel plate of steel tube surface brightness), can be arbitrary length.Therefore, it reflects its economy and aesthetics in the application of high precision, medium and low pressure fluid.

According to the welding technology can be divided into automatic welding, manual welding.Automatic welding usually USES submerged arc welding, plasma welding, manual welding generally USES argon arc welding.

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

By purpose is divided into general welded pipe and tube heat exchanger, condenser, pipe, galvanized welded pipe, oxygen blowing metric welded pipe, welded pipe, wire casing, roller tube, deep well pump pipe, auto tube, transformer, electric welding thin wall pipe, welded pipe and spiral welded pipe
