Seamless steel pipe 7




The difference between 16mn seamless steel pipe 8162 and 8163 fluid pipe 20 steel
The difference between 16mn seamless steel pipe 8162 and 8163
The difference between GB8162 seamless steel pipe and GB8163 seamless steel pipe The difference between seamless steel pipe GB8162 and GB8163 GB8162 "Seamless steel pipe for structure". The difference between GB8162 seamless steel pipe and GB8163 seamless steel pipe The difference between seamless steel pipe GB8162 and GB8163 GB8162 "Structure "Seamless steel pipe", this standard applies to general structure, seamless steel pipe for machinery structure, GB8163 "Seamless steel pipe for conveying fluid" standard applies to general seamless steel pipe for conveying fluid. Its main difference from GB8162 is GB8163 steel pipe is subjected to hydraulic test or ultrasound (a sound wave with a frequency higher than 20,000 Hz), eddy current (also known as: Foucault current), magnetic leakage detection. Therefore, the pressure of the pipeline steel pipe For standard selection, GB8162 standard should not be used.
16Mn Hardness:
16Mn hardness (Hardness) can not be used HRC, generally 140HBS, if you have to use HRC conversion, 140/10 is enough

Company (Company) is an annual agent of ten major steel plants including Baotou Steel, Chengdu, Shanghai, Anshan Iron and Steel, West Steel, Metallurgical Steel, Anshan Iron & Steel, Henggang, Changzhou Iron & Steel, and Germany, Japan, and Russia. The materials for the seamless steel pipe standing resources (The material) are: 10 #, 20 #, 35 #, 45 #, 16M
N, 27SiM
N, 10CrMo910, 15CrM
O, 15CrMoG, 35CrMo, etc. Seamless steel pipes are made of a single piece of metal and have no seams on the surface. They are called seamless steel pipes. According to the production method, seamless tubes are divided into hot rolled tubes, cold rolled tubes, cold drawn tubes, extruded tubes, and jacked tubes. Implementation of national standards: GB / T8162-99 structural tube, GB / T8163-99 fluid tube, GB / T3087-99 medium and low pressure boiler tube, GB / T5310-95 high pressure boiler tube, GB / T6479-2000 chemical fertilizer special tube, 27SiMn hydraulic ( hydraulic) support pipe, high-pressure alloy pipe, GB / T9948-85 petroleum cracking pipe GB9948-88, geological drilling pipe YB235-70, automobile (auto) axle casing YB / T5035-96 and other standard seamless steel pipes Our company has more than 10,000 tons in stock and more than 1,000 varieties for you to choose. The leading products are: structural tubes, fluid tubes, boiler tubes, fertilizer special tubes, alloy tubes, special-shaped tubes, precision (precise ) Cold-drawn tubes, large-caliber thick-walled tubes, and processing (machinery) processing tubes. (Hydraulic support tube 27SiM
N, blast furnace drill pipe, petroleum casing J55, N80) and so on. The difference between GB5310 seamless steel pipe and seamless steel pipe: 1. The obvious difference from seamless steel pipe is that it has high dimensional accuracy, which can reach 0.05mm. 2. The inner and outer diameter surfaces of precision steel pipes have a high surface finish, and customers can use them directly without processing; while ordinary seamless steel pipes require customers to lathe and polish. The production process of B3087 seamless steel pipe production can be divided into four basic methods: cold drawing, cold rolling, hot rolling, and hot expansion. The material of steel pipes is 10 #, 20 #, 35 #, and 45 # are called ordinary steel pipes. Types of steel pipes; seamless steel pipes for structures, seamless steel pipes for conveying fluids, low, medium and high pressure boilers (Boilers); seamless steel pipes; petroleum cracking pipes; alloy seamless steel pipes, bearing steel pipes, special welded pipes, spiral Pipe, zinc (galvanization) pipe, stainless steel (stainless acid-resistant steel) pipe, titanium (Ti) alloy pipe, outer hexagonal steel pipe, rectangular pipe, shaped pipe, etc. The plates are: carbon (C) plain plate, manganese plate, container plate, stainless steel plate, titanium steel plate, etc. The Special Steel Department also sells various special steels, die steels, and alloy round steels. Company (Company) has sufficient inventory and complete specifications.
