Q:Welded and seamless steel pipe how to distinguish?
Different processing technology:Seamless tubes are made of quality carbon steel or alloy steel. Processing technology of seamless pipe hot rolling and cold drawing is divided into two ways, and the tube is generally based on welded.
Q:Seamless steel pipe is how to do it?
1. seamless steel tubes for structural purposes (GB/T8162-1999) are seamless steel tubes for general structural and mechanical construction.2. seamless steel pipe for fluid transportation (GB/T8163-1999) is used to transport water, oil, gas and other fluids of general seamless steel pipe.3. seamless steel tubes for low and medium pressure boiler (GB3087-1999) is used in the manufacture of various structures of low and medium pressure boiler superheated steam pipe, superheated steam pipe, boiling water pipe and boiler flue tube, pipe and brick arch tubes of high quality carbon steel hot rolling and cold drawing (rolling) seamless steel tube.4. high pressure boiler seamless steel tube (GB5310-1995) is used for the manufacture of high-pressure and above the pressure of water boiler heating surface for high-quality carbon steel, alloy steel and stainless steel heat-resistant seamless steel pipe.5. high pressure seamless steel tube (GB6479-2000) for chemical fertilizer equipment is a kind of high quality carbon structural steel and alloy steel seamless pipe for chemical equipment and pipes of working temperature of -40~400 DEG C and working pressure of 10~30Ma.6. seamless steel tubes for petroleum cracking (GB9948-88) are tubes, heat exchangers and seamless steel tubes used in refineries.
Q:How to distinguish seamless pipe and welded pipe?
If it is seamless pipe, the port can be seen inside and outside the pipe there is no welding meat exists, and even if the welding pipe welding processing, the pipe weld is very easy to observe.
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
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 the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:Material of welded steel pipe
GB/T14980-1994 (large diameter welded pipe for low pressure fluid delivery). Mainly used to transport water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses. Its representative material is Q235 grade a steel.GB/T12770-1991 (stainless steel welded pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotels and restaurants, decorations and other mechanical parts and structures. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:Are steel tubes and round steel in weight or length when purchased?
The price must be measured by weight, and the length, volume and other specifications should be entered
Q:Is the electric pipe used with steel pipe or PVC pipe?
In industrial designs, galvanized steel tubes are generally used for laying electric tubes, especially in the case of explosion protection.The benefits of galvanized steel pipe is not easy to damage, can prevent the destruction and damage of environmental forces to a certain extent, a junction box, check for export, export lines and other accessories, construction and maintenance in explosion-proof environment can be exempted from hot work. The disadvantage is higher cost.The PVC tube is less costly, but less impact resistant.
After more than a decade’s construction and development, we have taken a leading position in seamless steel tube industry in China. In the year 2007, it awarded Famous-brand product Certificate. Besides, we have been named as excellent supplier of Qualified Products by our customers for several times.
