The introduction of stainless steel welded pipe
Stainless steel welded pipe is made of stainless steel strip or sheet crimped by welding process. It has the characteristics of high production efficiency, low cost, flexible specifications, etc., and is widely used in petroleum, chemical, construction, food, machinery and other fields. According to the different welding process and surface treatment, stainless steel welded pipe can be divided into many types, such as ordinary welded pipe, polished welded pipe, bright welded pipe and so on.
Welding process
The main welding process of stainless steel welded pipe includes:
TIG welding (Tungsten inert gas welding) :
Welding is performed using tungsten electrodes and inert gases such as argon.
Suitable for thin-wall pipe and high-precision welding, with high weld quality and smooth surface.
Plasma welding:
The use of plasma arc welding, energy concentration, welding speed.
Suitable for thick wall pipe and high strength requirements.
Laser welding:
Laser beam welding, high precision, small heat affected zone.
Suitable for high precision, high quality welding requirements.
High Frequency Welding (HFW) :
Welding edges are heated by high frequency current, suitable for mass production.
Low cost, high efficiency, but the weld quality is slightly lower than TIG welding.
Submerged Arc Welding (SAW) :
It is suitable for the production of thick wall pipe and large diameter pipe, and the welding efficiency is high.
specification
- Material: Common materials include 304, 304L, 316, 316L, 321, 310S, etc.
- Outer diameter: usually 6mm to 2000mm, can be customized according to demand.
- Wall thickness: Common range is 0.5mm to 30mm.
- Length: usually 6 meters, can also be customized according to customer requirements.
- Surface treatment: polishing, pickling, sandblasting and other treatments can be carried out according to demand.
Standard
The production and use of stainless steel welded pipes meet the following international and industry standards:
- ASTM A312/A312M: Standard for seamless, welded, and cryogenically processed Austenitic stainless steel pipes.
- ASTM A269: Universal Standard for seamless and welded Austenitic stainless steel pipes.
