Description:

 

Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made by welding steel or steel strip after curling and forming by a unit and a die. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications.

 

Welded steel pipes have high precision, uniform wall thickness, high brightness on both the inside and outside of the pipe (the surface brightness of the steel pipe is determined by the surface grade of the steel plate), and can be made to any length.

Advantages of Stainless Steel Welded Pipe: 

 

🔹Excellent corrosion resistance: Stainless steel welded pipes are made of high-quality stainless steel such as 304 and 316L, with excellent corrosion resistance, suitable for use in a variety of corrosive media and various environments.

 

🔹Good sealing performance: Stainless steel welded pipes use high-temperature welding technology, with smooth welds and excellent sealing performance, which prevents the risk of pipeline leakage.

 

🔹High temperature resistance: Stainless steel welded pipes can withstand temperatures above 800 degrees. Even if used for a long time at high temperatures, they will not deform, crack or age.

 

 

Applications:

 

Petrochemical, pharmaceutical, food, power generation equipment, shipbuilding industry, refrigeration equipment, seawater desalination equipment

 

 

Surface Finish:

 

🔸1D -- The surface has discontinuous granular shape, also known as fog surface.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

 

🔸2D - A slightly silvery white colour.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

 

🔸2B -- Silver white with better gloss and flatness than a 2D surface.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.

 

🔸BA - Excellent surface gloss, high reflectivity, like a mirror surface.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.

 

🔸No.3 -- Good gloss, coarse grain surface.

Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).

 

🔸No.4 -- Good gloss, fine lines on the surface.

Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).

 

🔸HL -- Silver grey with hair streaks.

Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.

 

🔸MIRRO -- Specular.

Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
