316 Stainless Steel Pipe Specifications

316L stainless steel pipe is widely used as a building pipe. The shape of this steel pipe is a long circular hollow steel pipe. 316L stainless steel pipe will be used in mechanical equipment, petrochemical equipment, medical use, food and light industry and other transmission pipelines or mechanical components. Here is the difference between 316L stainless steel pipe and 316 stainless steel pipe.

Because 316L stainless steel has lower carbon content and is more conducive to welding processing, 316L stainless steel pipe is more expensive than 316 stainless steel pipe, but the difference is not great. In addition, 316L stainless steel can also be called ultra-low carbon version 316 stainless steel.

The tensile strength of 316 stainless steel pipe is greater than that of 316L stainless steel pipe. The tensile strength of 316 stainless steel is required to be greater than 520mpa, and the tensile strength of 316L stainless steel is only required to be greater than 480mpa. This is because carbon is a strong austenite forming element, which can significantly improve the strength of stainless steel pipes.

Because the cost difference between ordinary 316 stainless steel and 316L stainless steel is not too large, and the ability and weldability of 316L stainless steel are obviously better than ordinary 316 stainless steel, 316L stainless steel is usually selected first. From the perspective of producers, because the demand for ordinary 316 stainless steel is small, stainless steel plants are not willing to produce. Therefore, the actual circulation in the market is basically low-carbon 316L stainless.

We can produce 316 stainless steel pipe with various specifications

316 stainless steel pipe Wall thickness specification

Generally, it only depends on its inner diameter and wall thickness, and its length can be determined according to the needs of customers. The specifications of common stainless steel pipes on the market are: inner diameter of more than 6.0mm and wall thickness of less than 13mm; The inner diameter is greater than 30mm and the wall thickness is greater than 1.2mm; The inner diameter is greater than 30mm and the wall thickness is less than 1.2mm.

Wall thickness specification of stainless steel pipe 316L

316 stainless steel pipes are 0.8mm, 1mm, 1.2mm, 1.5mm, 2mm, 2.5mm and 3mm respectively. The stainless steel pipe 316L with this thickness can bear the pressure of 1.6Mpa ~ 2.5MPa or even greater when put into use.

These wall thicknesses of stainless steel pipe 316L correspond to DN15, DN20, DN25, DN32, Dn40, DN50, dn60, DN65, DN80, DN100, DN125, DN150, DN200, DN250 and DN300
