Classification of ASTM 304 12 inch welded low price stainless steel pipe

ASTM 304 12 inch welded low price stainless steel pipe must have been seen in our daily life. It has good corrosion resistance and is widely used in many fields, and can also be used as decorative items. It can be divided into various types according to different situations. Everyone should master some skills when purchasing, choose the correct specifications and wall thickness, and also look at the qualifications of the seller. These factors have a certain impact on everyone's choice. . The following is a detailed introduction to the classification of ASTM 304 12 inch welded low price stainless steel pipe!

What are the classifications of ASTM 304 12 inch welded low price stainless steel pipe?

1. Classification by cross-sectional shape: Stainless steel pipes can be divided into round pipes and special-shaped pipes according to the cross-sectional shape. Special-shaped tubes include rectangular tubes, diamond tubes, elliptical tubes, hexagonal tubes, octagonal tubes and asymmetric tubes of various cross-sections. Profiled tubes are widely used in various structural parts, tools and mechanical parts.

2. Classification according to the shape of the pipe end: Stainless steel pipes can be divided into plain pipes and threaded pipes (threaded pipes) according to the state of the pipe ends, and threaded pipes can be divided into ordinary threaded pipes and special threaded pipes. For some special pipes, in order to compensate for the influence of the thread on the strength of the pipe end, the pipe end is usually thickened before tapping.

3. Classification by material: divided into ordinary carbon steel pipe, high-quality carbon structural pipe, alloy structural pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe, bimetallic composite pipe, plated pipe, etc., in order to save precious metals and meet special requirements. There are many kinds of stainless steel pipes, with different uses, different technical requirements and different production methods.

4. Classification by production method: ASTM 304 12 inch welded low price stainless steel pipe is divided into seamless pipe and welded pipe according to production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold drawn and cold rolled pipes are the secondary processing of steel pipes; welded pipes are divided into straight seam welded pipes and spiral welded pipes.
