Difference between stainless steel welded pipe and seamless pipe


Stainless steel pipe is divided into stainless steel welded pipe and stainless steel seamless pipe according to the production process. What's the difference between the two?



1. Differences in production process:

Stainless steel welded pipe: carbon steel plate or steel belt through the generator set and grinding tool rolled up and then welding. The welding method is not the same, can be divided into straight seam stainless steel welding pipe and spiral stainless steel welding pipe. Stainless steel welded pipe production efficiency is high, more varieties and specifications. And welding pipe in the production process to prevent several heating production, production and processing process more protection of the environment.

Stainless steel seamless tube: the round tube is heated, and then, according to the production process of cold rolling, cold drawing or extrusion. The thicker the pipe wall of the product is, the more reasonable and useful it is. The thinner the wall thickness is, the cost of the product will rise significantly.


2. Differences in appearance:

Stainless steel welded pipe: Because of the plate cold forming production process, so the precision of the welded pipe is high, uniform wall thickness, high brightness of the internal pipe wall, can be arbitrary size, specifications and models are various.

Stainless steel seamless pipe: Seamless tube precision is low, the wall thickness is not uniform, the production and manufacturing method is limited, the tube wall brightness is low, the cost of fixed size is rising, stainless steel seamless tube wall is easy to have small black spots and difficult to remove, usually thick tube wall.

3. Difference in price:

Seamless pipe in the production process is more cumbersome, its price than stainless steel welded pipe to expensive.


4. Difference is application:

Stainless steel welded tube: Because of its excellent appearance, commonly used in decorative pipe, game props pipe, product pipe, mainly used for conveying water, liquefied petroleum gas, gas, and heating hot water or steam and other usually lower operating pressure liquid.
