Steel-plastic composite pipe and plastic-lined steel pipe have always been foolishly confused between the two kinds of pipes, do not know their respective properties, and do not know where they are used respectively. In fact, the difference between steel-plastic composite pipe and plastic-lined steel pipe is quite Big, you can’t see that the main reason […]
Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. In addition to […]
1. What are the executive standards for stainless steel pipes in China? No. Standard type Production standard 1 European standard EN10216-5; EN10216-2 2 German standard DIN 17456; DIN 17458 3 American Standard ASTM A312; A213; A269; A511; A789; A790; ASME SA213; SA312; SA789; SA790; ASTM B423, ASTM B407, ASTM B668, ASTM B163; ASME SB163, ASME […]
Stainless steel pipe has high strength, strong corrosion resistance, good toughness, vibration shock resistance and seismic performance, low temperature does not become brittle, water transmission process to ensure the purity of the water quality, and durable and can be regenerated to do decorative materials to use. Thin-walled stainless steel pipe has the following outstanding advantages: […]
For any steel pipe, there is a bearing capacity, and the house pipe is no exception. Strength refers to the performance of metal materials to resist damage (excessive plastic deformation or fracture) under static load. Since the load acts in the form of tension, compression, bending, shearing, etc., the strength is also divided into tensile […]
Galvanized square tubes are divided into hot-galvanized square tubes and cold-galvanized square tubes from the production process. It is precisely because of the different addition of these two kinds of galvanized square tubes that they have created many different physical and chemical properties. In general, they have many differences in strength, toughness and mechanical properties. […]
It is generally known that steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a […]
Galvanized steel pipes are divided into hot-dip galvanizing and cold-galvanizing. Hot dip galvanizing is the process of immersing the tube in a high temperature zinc bath to allow zinc to penetrate the surface of the steel. The surface of the pipe has a thick zinc layer and corrosion resistance higher than that of cold-dip galvanizing. […]
When we talk about the basic production process of steel, first is obtain iron ore, coke coal and other raw materials, and then they are refined into iron in the ironmaking blast furnace; the next step is to use raw iron as raw material and smelt into steel with different steelmaking furnaces; The shape of […]
Steel flat bar products are widely and professionally applied on manufacturing industry of steel structure, mechanical manufacture, automobile industry, Mine machinery and hoisting machinery, etc. The uses of steel flat bars can be considered according to its hot rolled and cold drawn process. Hot rolled flat bar steel – Commonly used for construction purposes such […]
