Q:25 of the steel pipe with 6 in charge of what is the difference?
Outer diameter representation of steel pipe:When the design is nominal diameter DN means diameter, should be nominal diameter DN and the corresponding product specifications table. Specification for unplasticized polyvinyl chloride pipes for building drainage, de (nominal outer diameter) * e (nominal wall thickness), (GB, 5836.1-92), polypropylene (PP) pipe for water supply, specifications by de * e (nominal outer diameter * wall thickness).
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
15CrMo is a steel Pearlite Heat-resistant steel, has high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloy elements in steel, the tendency of hardening of steel is obvious, and the weldability is poor.
Q:How can galvanized steel tubes be painted on the surface?
The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
Q:What does cathodic protection of steel tubes mean?
There are two ways of cathodic protection: sacrificial anode, cathodic protection and impressed current cathodic protection.Sacrificial anode: connect a living metal or alloy to a protective metal to form a galvanic cell. The active metal replaces the protected metal to lose electrons so that the protected metal is not corroded.
Q:Material of welded steel pipe
GB/T3092-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is: Q235 grade a steel.GB/T14291-1992 (mine fluid conveying welded steel pipe). It is mainly used in mine pressure air, drainage and vertical seam gas welding pipe. Its representative material is Q235A, B grade steel.
Q:Is the PVC tube a plastic tube or a plastic tube?.
It's plastic tubePolyvinyl chloride (Poly, Vinyl, Chloride, PVC)PVC is a VCM monomer (vinyl, chloride, monomer), in peroxide, azo compounds and other initiators;
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN250 is the nominal diameter, the outer diameter of the steel pipe is 273mm, the thickness is above 6.5mm.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
Q:How do you solder purple copper plate and steel tube?
When the copper pipe and the size is not too large, such as 10 mm below the pipe welding, brazing is suggested, with brass solder, such as Wei Odin 201 solder, with supporting solder paste, with a neutral flame welding, the copper plate is heated to about 800 degrees, and then use the solder with 201 Wei Odin 201-F in solder welding, welding wire with melt molding.
Q:How big is the seamless steel tube of DN50?
This refers to the diameter of the steel pipe is 50 mm, DN50 steel pipe diameter is 60.3 mm, that is, 60.3 * 5 mm steel pipe
