The production process of welded stainless steel pipe
Posted On 11/23/2017 13:16:44 by flange

The production process of welded stainless Steel pipe
The main industry is the nominal pipe diameter of more than DN700 in the pipeline. Slotted pipe not only includes the straight pipe, and comprises a spiral weld pipe. The main specifications and production of welded stainless Steel pipe Steel pipe with nominal diameter 700mm multiplied by the thickness of 10mm (denoted as 711x10)... Read More



Advantages and disadvantages of duplex stainless steel
Posted On 11/22/2017 12:38:20 by flange

Duplex stainless steel is the stainless Steel material that contains both ferrite phase and austenite phase in the microstructure of the metal. They are about half of each. But in practical applications, the ratio of a phase is better than that of 40-60%. Consider two organizational characteristics, through the organization of correct control of chemical composition and heat treatment process, can make excellent toughness and weldability of austenitic stainless Steel and ferritic stainle...

The purpose of bright annealing process for stainless steel
Posted On 11/21/2017 12:17:43 by flange

The process of bright annealing of stainless steel aims to obtain sufficient metallographic structure by eliminating the work hardening and, on the other hand, to obtain an oxide free bright surface. Here is a detailed discussion of the role of these two aspects.
1. Excellent microstructure of stainless Steel can be obtained by eliminating hardening... Read More



Corrosion Resistance of 316 Stainless Steel Pipes in Seawater
Posted On 11/20/2017 15:43:14 by flange

Although 316 stainless Steel pipes are usually used in marine environments, the corrosion resistance of the Steel and seawater is limited and can not be resistant to corrosion in all states. Which is more susceptible to local corrosion, mainly crack corrosion and point corrosion. So this limits the scope of application of 316 stainless Steel tubes in marine environments.
Factor... Read More



What are the welding process of stainless steel welded pipe
Posted On 11/19/2017 12:06:03 by flange

​Stainless Steel welded pipe is also called the welded stainless Steel pipe, usually with unit and mould will be stainless Steel sheet or strip coiling molding made of stainless Steel welded pipe again, after the production process of this product is simple, so the production efficiency is also good, more varieties of specifications, traditionally the use strength than seamless Steel tube. But along with the progress of the technological level and production equipment, the welded pipe... Read More
