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 is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Seamless steel pipe material is steel, but also seamless, high strength, used in high pressure, harsh environment occasions. The galvanized pipe is only made on the steel tube, which is similar to the so-called antirust paint
Q:What does "buried steel pipe" 6*2SC100 mean?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
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:What time what time for gas pipeline steel pipe PE pipe
PE pipe is suitable for medium voltage and low voltage 0.4MPa below the pressure pipe wall thickness. According to the different pressure is not the same, so the steel tube can be used for high pressure.
Q:How much is 4 inches steel tube MM?
The standard wall thickness is 4mm, so the outer diameter is 114mm.
Q:Can galvanized steel tubes simmer?
I make the steel pipe, galvanized pipe and water conveying pipe material is the same, can be bent, specific to what to look at the furnace, can refer to a single material
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
The quality of the steel pipe should be in line with the national standard "stainless steel seamless pipe for fluid transportation" (GBT 14976-2012) requirements.
Q:What does "1.5" steel tube mean?
DN refers to the nominal diameter of the pipe (also known as nominal diameter), all piping accessories in the piping system are numerically represented in order to distinguish the parts that are represented by threads or outside diameters. Nominal diameter is used as a reference, after rounding the figures, and processing numerical value is not exactly the same, nominal diameter can be expressed as metric mm, also can be used in English in.
