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 place must use galvanized steel pipe to make lighting line?
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:Is there a weld on the outer wall of seamless steel tube?
As you have said this, you have to fake goods is seamless, commonly known as to seamless steel pipe, seamless steel pipe is welded pipe weld reinforcement, and then go inside and outside the weld is worn away, and then burn side is that you say is that, after you can see the wall friction of a weld, is not too obvious. Like a polished, but no wall bulge, can not see the seam,
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: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:How can seamless steel tubes be produced?
The material of rolling seamless tube is round tube blank, and the billet is processed by cutting machine to grow about 1 meters, and sent to the furnace by conveyor belt. The billets are heated into a furnace and the temperature is about 1200 degrees celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. When the round billet is released, it should be punched through the pressure piercer. The most common punching machine is a cone roll piercer, which has high production efficiency, good product quality, large perforation and expanding diameter, and can be used in various steel grades. After the perforation, the round tube blank has been successively rolled, rolled or squeezed by three rollers.
Q:How to make the magnetic steel, can be like a magnet?
Magnetization. Winding the insulated wire on the object, passing in the direct current, and taking it down after a period of time.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
The urban water supply pipeline cleaning is a very necessary work, it can not only improve the transmission efficiency of pipeline to reduce energy consumption, but also to clear the pipeline dirt, remove two pollution, improve water quality, protect the people's physical and mental health.
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:Why seamless steel pipe called seamless steel pipe?
Seamless is relative to welded steel pipe, because welded steel pipe is welded with steel strip, seamless steel pipe is made of whole round steel empty, no welding seam.
