Stainless steel welded pipe is a kind of pipe made of stainless steel material, through the welding process of stainless steel plate or strip welded into the shape of the pipe, the inner and outer surface of the pipe is smooth and the dimensional accuracy is high. Stainless steel welded pipe can be used in construction, machinery, chemical, food, medicine and other fields, is an important pipeline material.
Characteristics
The main characteristics of stainless steel welded pipe include the following aspects:
1. Good corrosion resistance: Stainless steel welded pipe is made of stainless steel material, which has good corrosion resistance and can be used in acid, alkali, salt and other corrosive environments for a long time.
2. High strength: Stainless steel welded pipe has high strength and can withstand large pressure and tension.
3. Excellent welding quality: Stainless steel welded pipe uses high quality The welding technology, the weld seam is flat, no porosity, no slag, excellent welding quality.
4. Beautiful appearance: Stainless steel welded pipe has a smooth appearance, good surface treatment, with a high degree of beauty.
Parameters
Stainless steel welded pipe main parameters include the following aspects:
1. Material: Stainless steel welded pipe material is usually 304, 316L and other stainless steel materials.
2. Size: Stainless steel welded pipe specifications include outside diameter, wall thickness and other parameters, the common outside diameter of 6mm, 8mm, 10mm, 12mm, etc., wall thickness generally ranges from 0.5mm to 3mm.
