Corrosion resistance. Most ASTM A106 gr. A seamless steel pipe must have excellent corrosion resistance. Seamless steel pipe is similar to class I and II tableware, kitchen supplies, electric water heater, water dispenser, etc. Some foreign-funded enterpr

During smelting or hot processing of ASTM A106 seamless pipe, due to the influence of some factors (such as non-metallic inclusions, gas, process selection or improper operation, etc.), defects will occur on the inside or surface of steel, which will seri

The chromium-containing stainless steel flange pipe fittings also integrate mechanical strength and high extensibility, easy to process and manufacture parts, and can meet the needs of architects and structural designers.

Pipeline flanges are divided into the following six basic types according to their connection with steel pipes: flat welding flanges, butt welding flanges, socket welding flanges, loose flanges, threaded flanges and integral flanges.
