Medium and low pressure steam boiler tubes are made of steel ingots or solid tube blanks through perforation, and then made by hot rolling, cold rolling or cold drawing. Seamless steel pipe has a tight position in China’s steel pipe industry. According to incomplete statistics, there are about 240 seamless pipe manufacturing enterprises and more than 250 seamless steel pipe units in China, with an annual output of about 4.5 million tons. From the perspective of caliber, ＜ φ 76, accounting for 35%, ＜ φ 159-650, accounting for 25%. In terms of types, 1.9 million tons of general purpose pipes, accounting for 54%; 760000 tons of kerosene pipes, accounting for 5.7%; 150000 tons of hydraulic prop and tight pipe, accounting for 4.3%; Stainless pipe, bearing pipe and automobile pipe are 50000 tons, accounting for 1.4%.

From left to right is a four-part combination of a number + a letter + one or two letters + two numbers. The number in the first part is one of "3, 4, 5", which represent the strength levels of the steel bars with yield strengths of 300MPa, 400MPa and 500MPa respectively. The letter in the second part is a description of the type of steel bar. If the letter in this position is empty, it means hot-rolled steel bar, K means waste heat treated steel bar; C means fine-grained steel bar; E means earthquake-resistant steel bar; W means weldable steel bar. The meaning of one or two letters in the third part is the steel factory that produces steel. For example: AY is Anyang Iron and Steel, CG is Chengdu Iron and Steel, T is Tangshan Iron and Steel, X is Xuanhua Iron and Steel, and HG is Handan Iron and Steel. The two digits in the fourth part represent the diameter of the steel bar, 6-50mm.

Stainless steel strip is a thin steel plate supplied in coils, also called strip steel. There are imported and domestic products, divided into hot-rolled and cold-rolled. According to the needs of different users, we can also order a variety of special-shaped steel materials.In order to ensure that the yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.
