- Inquire about price/MOQ

Q:Is the same specification seamless steel pipe more expensive than welded pipe?
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.
Q:Seamless steel pipe is how to do it?
Probably with 10, 20, 30, 35, 45 and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other composite steel hot-rolled or cold rolled.
Q:What does "buried steel pipe" 6*2SC100 mean?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel pipes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube. The outer diameter of hot-rolled seamless tube is generally greater than 32mm, the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel tube can reach 6mm, the wall thickness can be up to 0.25mm, the outer diameter of thin-wall pipe can be 5mm, the wall thickness is less than 0.25mm, and cold rolling has higher precision than hot rolling dimension.
Q:Are metal spiral tubes the same as metal bellows?
The corrugated pipe is extruded by the extruder, the winding pipe is wound in a circle, and the prestressed metal corrugated pipe is a reserved channel.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
And the method of magnetic field created by means of electromagnets or permanent magnets. For analysis of residual magnetism, see table (1), select the demagnetizing method and system in combination with the conditions of the construction site (for example, given equipment, etc.). Table 1 magnetic remanence grade and welding conditions
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
High frequency welding uses the skin effect to concentrate the energy of the high frequency current on the surface of the workpiece, and uses the proximity effect to control the position and range of the high frequency current flow path. The speed of the current is very fast, it can in a short period of time will be adjacent to the edge of the steel plate heating, melting, and through the extrusion docking, each has its own advantages, but also each has its own shortcomings. Generally according to specific circumstances, specific analysis of specific choices.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;
Q:RC is it welded steel pipe or galvanized steel pipe?
Common pipelines in construction are as follows:SC: welded steel pipeTC: wire tubes, thin steel tubesPC: rigid plastic pipesCT: cable trayCP: metal hoseSR: steel grooveRC: water gas pipe
