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 does "DN25 PN16" mean?
The welded steel pipe can be divided into thin-wall steel tube, ordinary steel pipe and thickened steel tube according to the thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube. "DN25" means the inner diameter of the steel pipe is 25MM.
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
purpose2.1 seamless tubes are widely used. General purpose seamless tubes are rolled from plain carbon structural steel, low-alloy structural steel or alloy structural steel, with the most output and are used primarily as pipes or structural parts for conveying fluids2.2, divided into three kinds according to the supply of different uses: the supply of a, according to the chemical composition and mechanical properties; the supply of B, according to the mechanical properties; the supply of C, according to the hydraulic pressure test. According to a, the B class steel supply, such as for under fluid pressure, but also to the pressure test.2.3. Seamless tubes for special purposes include seamless tubes for boilers, seamless tubes for geology, and seamless pipes for petroleum use
Q:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:How long are the seamless tubes? Are they six meters long?
6 meters of a root in general need to be customized, seamless tubes are mostly seven meters above the variable foot
Q:What does GALV mean in a steel tube?
GALV is the abbreviation of English galvanized (Galvanized), which means galvanized steel pipe.
Q:Galvanized steel pipe DN100 and SC100
DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
Q:How many fasteners are there in a ton of steel tubes?
In general, 180-200 fasteners per ton of steel pipe.
Q:How to make the steel pipe spray paint is not easy to fall off?
You're not usually advised to do it yourself, because you can't do it yourself. General powder coating, spray before the treatment is very strict, to be high temperature baking, and their spraying are dry paint, it does not add hardening agent, that is, the surface dry, but not hard, not wear-resistant. So don't scrape off the paint, or you'll look good after spraying, and it will be ugly in a few days,.If you really like to look good, you can buy some stickers back to paste, without affecting the appearance..
Q:45 and 316 which steel tubes are of high hardness?
This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
