Q:What's the difference between seamless steel pipe and welded pipe?: Welded steel pipe, also known as welded pipe, is made of steel or strip after the formation of welding welded steel pipe, usually 6 meters in length. Welded steel pipe production technology is simple, high production efficiency, varieties and specifications, equipment investment is less, but the general strength is lower than seamless steel pipe.

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:Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?: SC is welded pipe, not galvanized pipe, RC is galvanized pipe, MT is lined pipe laying

Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?: Dimensions of ordinary steel tubes (taken from GB/T 17395-1998)The theory of weight / (kg/m) | wall thickness (2.9 3.0mm: 3.33)

Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?: D108: refers to the outer diameter of 108mm;4: refers to the wall thickness of 4mm.

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:Difference between cold rolled steel pipe and common steel pipe: From the above point of view, the hot rolled steel pipe used in fluid transport, mechanical structure and other requirements of the size of the situation is not high, cold-rolled steel pipe used in precision instruments, hydraulic systems, pneumatic and other places demanding.

Q:Why should the weak electricity be pre buried with galvanized steel pipe?: Galvanized steel pipe with hot-dip galvanizing or galvanized coating on it. Galvanizing can increase the corrosion resistance and prolong the service life of the steel pipe. The use of galvanized pipe is very wide, except for water, gas, oil and other general low pressure fluid pipeline, is used in petroleum industry especially offshore oil well pipe and oil pipe, chemical coking equipment oil heater, cooler, oil pipe exchanger for coal distillation, and support piles, Zhanqiao mine tunnel the tubes.

Q:What is the outer diameter and wall thickness of DN40 steel pipe?: DN40 pipe diameter 48.3mm diameter, allowable deviation of plus or minus 0.5mm it depends on what you have, the outside diameter of 45, there are other dimensions, you can see the manual

Q:Is the electric pipe used with steel pipe or PVC pipe?: When the electric wire pipe is laid, the steel pipe can be adopted, or the plastic pipe can be adopted, but the steel tube must not be used in the ceiling. The standard explanation is for rat bite.
