Q:What is the single length of galvanized steel pipe?
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned.
Q:Material of welded steel pipe
GB/T14980-1994 (large diameter welded pipe for low pressure fluid delivery). Mainly used to transport water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses. Its representative material is Q235 grade a steel.GB/T12770-1991 (stainless steel welded pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotels and restaurants, decorations and other mechanical parts and structures. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
Q:What material is RHS in the steel tube?
RHS is a rectangular hollow section steel. The RHS structure represents a rectangular hollow section steel.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
Carbon steel is actually relative to alloy steel, mainly carbon content, and 20# seamless steel is carbon steel! In addition, there are stainless steel, stainless steel is considered a kind of alloy steel, but the processing is not the same, the performance is not the same, good looking outside!The description of the material in alloy steel is actually the content of the metal elements in the steel (usually the percentage number).
Q:Welded and seamless steel pipe how to distinguish?
Different uses:Mainly used for seamless pipe or structural parts of the transmission fluid, mainly used in machinery industry, and seamed steel pipe is mainly used in the construction industry, such as water, gas, compressed air and low pressure fluid. But seamless steel tubes are used in all pressure pipes.
Q:The plastic pipe and steel pipe difference
In fact, including the steel plastic pipe plastic pipe, but on the market all the steel plastic pipe and plastic lining steel pipe is synonymous, lined with plastic pipe is made of galvanized steel pipe internal set of plastic pipe manufacturing process, process using high pressure steam to both adhesion.
Q:What are the uses of welded steel pipes?
It is used to transport water, gas, air, oil and heating steam, and generally lower pressure fluid and other purposes of welded steel pipe. The wall thickness of the steel pipe is divided into ordinary steel pipe and thickened steel pipe. The end of the pipe is divided into non - threaded steel pipe (light pipe) and threaded steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2. The welded steel pipe for low pressure fluid transportation is used as the main pipe of galvanized steel pipe for low pressure fluid transportation except for directly conveying fluid
Q:What are the specific differences between flexible pipes and rigid pipes?
Choose from the waterproof performance:A rigid waterproof sleeve is a steel pipe with an outer wing (a steel ring made of a steel ring), mounted in the wall (mostly concrete walls), used for general pipe wall crossing, and is beneficial to the waterproof of the wall;The flexible waterproof casing except external wing ring, flange ring and internal wire like, and have complete sets sold, but also their own processing, for pipeline damping needs, such as pipes and pumps connected through walls.
Q:What is the diameter of the steel tube DN20?
The symbol is DN, the unit is mm, but omitted to write. Also available in English in.
Q:What are the main aspects of precision steel tubes?
Products according to their application areas are divided into: automotive, precision machinery tubes; power plants, nuclear power tubes; titanium and titanium alloy tubes; chemical tubes; varieties include colored, black; seamless; welding; general and special-shaped
