Stainless steel welded pipe is a crucial component in various industries, known for its durability, corrosion resistance, and versatility. This type of pipe is manufactured by welding together two or more pieces of stainless steel, creating a strong and seamless connection. Unlike its counterpart, the seamless pipe, welded pipe offers unique advantages in terms of cost-effectiveness and dimensional consistency.

Stainless steel welded pipes are available in various grades and specifications to meet different industry requirements:
A. Common grades: The most frequently used grades include 304, 304L, 316, and 316L. Each grade offers specific properties suitable for different applications.
B. ASTM A312 specification: This is a standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes.
C. Size ranges and schedules: Stainless steel welded pipes are available in a wide range of sizes, typically from 1/4" to 36" NPS (Nominal Pipe Size). Common schedules include 10, 10s, 40, 40s, 80, and 80s.
D. Wall thickness: The wall thickness of welded pipes is generally more consistent than that of seamless pipes, which can be an advantage in certain applications.

6.How to distinguish 304 and 201 stainless steel?
--1). Specification: the Bai composition is different. 304 has better quality and the price is expensive, but 201 is worse. 304 is imported stainless steel plate and 201 is domestic stainless steel plate.
2). 201 is composed of 17cr-4.5ni-6mn-n which is used for railway vehicles.While 304 is composed of 18cr-9ni, which is used for food production equipment, Xitong chemical equipment, nuclear energy, etc.
3). 201 has high manganese content, bright surface with dark brightness, high manganese content and easy to rust. 304 contains more chromium, the surface is matte and does not rust .The most important thing is that the corrosion resistance is different. The 201 corrosion resistance is not as good as that of 304.
4). The difference between 201 and 304 is the problem of nickel. The 304 nickel's content is more than 201.
5). Stainless steel is not easy to rust because chromium rich oxide is formed on the surface of the steel body to protect the steel body. Material 201 belongs to high manganese stainless steel, which has higher hardness, high carbon and low nickel than 304.
