Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
27SiMn =27 - steel pipe, which is a seamless steel tube material, the carbon content in 0.24 - 0.32%, SIMN single because it five elements (carbon manganese silicon Si, C, Mn, P P, S, guimeng sulfur) the high content of about 1.10 - 1.40%.
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The thread of the tightening (JDG) joint is unified with an outer thread, a wall thickness of 1.5mm, and a button (KBG). The thread of the joint is an internal thread, and the wall thickness is 1.0mm. Withholding type joint for the use of the same company and pipe connection to matching products with complete connection clamp buckle. Fastening and pressing type correctly connected and locked after no need to do a cross ground.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Overview of two processesHot-rolled (extrusion seamless pipe): billet, heating, perforation, three roll cross rolling, rolling or extrusion, tube to tube diameter (or reducing) - cooling - tube, straightening, pressure test (or testing), marking and warehousing.Cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.
Q:Galvanized steel pipe DN100 and SC100
Zinc plating, hot dip galvanizing and cold galvanizing, to see the design instructions and design requirements, which will explain
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Screw on the line, mainly anti-corrosion and insulation, seamless pipe caliber restrictions, so the price is high, with the most affordable screw can meet the requirements, 377 and 273 of the spiral 3920 yuan / ton, straight seam is about 4350
Q:A333gr6 steel pipe and domestic material of the same?
The SA333 standard in ASME (cryogenic seamless and welded nominal steel tubes), so A333-6 is a representation of the United States, followed by many countries.
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Is hot dipped plastic pipe steel?
The characteristics of hot dipped plastic pipe are:1., hot dipped plastic pipe superior anti-static performance: through the formula to add antistatic agent, so that its internal and external surface resistance value reached and exceeded the national industry standards.2., such as the use of plastic raw materials, add flame retardants. The flame retardant performance index conforms to the national standard, and the steel plastic composite structure has better flame retardance than the pure plastic pipe material, and is suitable for underground inflammable, explosive and other places.3. hot dip coating steel strong adhesion: steel surface after special treatment, curing, coating adhesion is greater than or equal to 30N/10mm.4., dense internal and external resin layer: coating thickness of more than 0.5 mm, no pinholes, with excellent corrosion resistance.The mechanical properties of plastic steel pipe superior 5. hot dip: can withstand the harsh conditions of use: coating steel has good toughness, high mechanical strength, impact bending and other foreign influence, has a strong bearing capacity, has better performance than other mine plastic pipes.6. hot dip steel corrosion and fouling, the fluid resistance is small: corrosion and fouling, especially suitable for the underground conveying high sulfur water and transport of calcium and magnesium plasma water, save the maintenance cost, service life is much higher than that of the other pipe, high economic benefit.7. self lubrication: smooth wall, no fouling, small transmission resistance, under the same conditions, can improve the transport capacity of 30%.8. convenient and reliable connectionThe utility model completely overcomes the defects of the difficult connection of the pure plastic mining materials, and can be connected with the underground steel pipe and the valve by using flanges, fast couplings, etc., and has strong interchangeability.
Q:Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?
Hot galvanized steel pipe galvanized color silver plated SC.MT wire pipe galvanized color silver plated or silver plated cold yellow fever.
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.
