Q:What is the single length of galvanized steel pipe?
The single length of galvanized pipe is 6 meters. The length of galvanized seamless steel tube is uncertain, depending on the length of seamless steel tube.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm. The standards in Shanghai are in line with national standards and 3.25mm can be used.Shelf tubes commonly used specifications, sizes are generally 48.3x3.0, 48.3x3.25, 48.3x3.5.
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:Seamless steel pipe and welded pipe what is the difference?
Identification method: see the inside of the pipe, because the external, will deal with the welded pipe is inside a gap, you can see some, some, is not easy to see, you can slowly by hand touch, or see the specifications are relatively thin, welded pipe
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:How are steel tubes represented?
Galvanized pipe: InchSeamless steel tube, welded pipe, nonferrous metal pipe, etc.: outer diameter x wall thickness
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel pipe mainly because of anti-interference and electrical connectivity, to prevent other strong magnetic strong signal to interfere with weak signal, while in the electrical connection, galvanized steel pipe can be directly connected to the bridge.
Q:What's the difference between seamless steel pipe and welded pipe?
Use, seamless steel pipe is generally used in the condition of higher use, such as temperature and pressure higher, corresponding to the requirements of stress corrosion, seamless steel pipe. With vice.
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:Is the same specification seamless steel pipe more expensive than welded pipe?
You need to see this in the interval that diameter, such as seamless pipe and welded steel tube 530*20 mm compared to 5450 yuan per ton, seamless pipe, welded steel pipe, which is 4550 yuan, small diameter 10*2 mm, seamless pipe will require far 10000 per ton, just need more than 6000
