Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
To look at the use of concrete after welding, if the stress is relatively large and thin galvanized pipe wall is recommended to not use welding, if the requirement is not high Po mouth welding should be welding depends on galvanized pipe material selection electrode generally no sealing material are 20
Q:What's wrong with the 3PP anticorrosive steel tube?
That is, polypropylene corrosion resistant coating of steel pipe, the biggest feature of this anti-corrosion coating is good heat resistance.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
Q:What quota should be installed for heating seamless steel pipe?
Should be in low carbon steel welding installation set industrial pipeline engineering quota, material to input the name and type of seamless steel pipe specifications and price; according to the description of the contents of related items can be set.
Q:How to make the internal tooth of the steel pipe?
Compared with the ordinary light pipe, tube can effectively prevent the formation of steam film between the seal and the pipe wall, increase the light disturbance flow inside the tube, the tube wall temperature is more uniform, which can avoid the light pipe damage, and improve the heat transfer efficiency of boiler. The number of thread head of internal thread pipe is 4, 6 head and 8 head according to need. The main materials are 20G, SA210C, T2, T12, 12Cr1MoVG, 15CrMoG, T22, T23 and so on. China needs 2.5~3.0 tons per year of inner thread tube.
Q:The difference between carbon and welded steel tubes
Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
Q:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
Q:Where is the difference between seamless steel pipe and welded pipe
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:What does "HBB" glass steel pipe mean?
Non electrical corrosion, non-magnetic, suitable for single core cable laying, and steel pipe is a magnetic material, special treatment must be taken to prevent the formation of eddy currents.
Q:What is a tight steel tube?
JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
