- Q:A333gr6 steel pipe and domestic material of the same?
- A333Gr.6 steel is no nickel steel is a kind of fine grain aluminum low temperature toughness of steel, therefore, also called Al killed steel. A333Gr.6 belongs to the United States ANSI and ASTM-SA333 cryogenic steel standards and is used at the lowest impact temperature of -46 degrees celsius. Its temperature, range of use and fracture toughness value are similar to those of domestic 16Mn steel (the minimum usage temperature of 16Mn steel is -40 degrees Celsius).
- Q:What's the difference between a rectangular tube and a rectangular steel tube?
- Rectangular tube is a kind of hollow long strip steel, also known as flat tube, flat square tube or square flat tube (Gu Mingsiyi). A large amount of pipe used to transport fluids, such as petroleum,Natural gas, water, gas, steam, etc., in addition to bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
- Q:What kinds of steel pipe are divided into?
- The steel pipe seamless steel pipe and welded steel pipe (tube) two categories. According to the section shape and can be divided into round tube shaped tube, round steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, triangular, octagonal shaped steel tube.Seamless steel pipe: seamless steel pipe is ingot or solid billet made by capillary hole, then hot, cold or cold drawing. Made of seamless steel pipe specifications with outer diameter * wall thickness mm. Number of seamless steel pipe cold and hot points of seamless steel pipe (DIAL) two categories.
- Q:How long are the seamless tubes? Are they six meters long?
- The usual length of steel pipe is as follows: hot rolled steel pipe 3000~12000mm and cold drawn steel pipe 3000~10500mm.
- Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
- Fastener type steel pipe scaffold, fastener is the connection between steel pipe and steel pipe, and its form has three kinds, namely right angle fastener, rotating fastener, butt fastener
- Q:Stainless steel tube, also known as why tube?
- Use can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc.
- Q:How to make the internal tooth of the steel pipe?
- Cylindrical thread can be used, if the tube is too long, you may consider a short tube with thread, and then welded to the long tube. Taper thread is more difficult to use than ordinary vehicle, and the tap is generally considered. The tap can be clamped on the tailstock.
- Q:Why seamless steel pipe called seamless steel pipe?
- Seamless steel pipe is a hollow section, without the joint round, square, rectangular steel. Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel pipe with a hollow section, as pipe conveying fluid, compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, bike frame and construction using steel scaffolding.
- Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
- Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe
- Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
- However, there are a variety of non GB steel tubes on the market, mainly in the wall thickness, and are thinner than the national standard requirements, you said that thickness may have, but the thinnest only about 2.6mm-2.7mm.
