Q:What is an electric welded pipe (EFW)? Seek help!
Pipe and pipe fittings should be suitable for the gap, usually with micro force insertion is appropriate, the gap is too large or too small will affect the quality of the interface.Check the depth of the plug and slip the spigot into the socket and position correctly.
Q:What are the specific differences between flexible pipes and rigid pipes?
Watch from outside:The rigid waterproof sleeve is made up of steel bushing and wing ring, and the structure is simple;The flexible waterproof sleeve mainly consists of flange sleeve, sealing ring, flange, pressure plate, wing ring, bolt and nut. The structure is complicated.
Q:How to distinguish seamless pipe and welded pipe?
Most of the welded pipe is six meters, the pipe has obvious welding marks, and seamless pipe wall without welding marks
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe must be installed underground, the steel tube can be exposed, when not all PE pipe for pipe laying, overhead installation. But the steel tube is easy to rust, so it can be used where the basic use of PE pipe buried PE pipe.There are galvanized steel pipe and seamless steel pipe, galvanized pipe can only be used for low-pressure homes
Q:What are the lengths of scaffold steel tubes?
Scaffolding steel pipe standard length is 6 meters, for easy use, respectively, 6 meters, 3 meters, 2 meters, 1.5 meters, 1 meters, etc., if there is a special length, you need to intercept.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:How many meters per ton of steel tube?
Formula of steel tube: (outside diameter wall thickness) * wall thickness *0.02466= per meter weight1000 divided by the weight per metre is how many meters per ton
Q:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
