Product  Descriptions :Hot Rolled API 5L Seamless Tube

The Hot Rolled Seamless Tube is manufactured through automatic continuous tube rolling mills.Precisely temperature (recrystallization temperature) controlling is required during different rolling processes,like initial rolling stage,finish rolling stage and curling stage,to achieve microstructure and mechanical structure of steel plates,Thus,they can be deformed to a large extend
Our mill could produce hot rolled seamless tube in ASTM,EN,GB,BS,DIN,GOST,JIS standard,it is our great honor to pass API,CE,ISO,CCS certificate,it proves that our goods are meet the high quality,this make us has obtained a great huge number of customers from abroad.

Q:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:Seamless steel pipe and welded pipe what is the difference?
The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Different materials, cast iron, steel seamless steel pipe; the different production process, cast iron is hot metal casting, steel rolling mill of seamless steel tube is through processing, different performance indexes, ductile iron diameter, wall thickness, crisp texture, relatively heavy, can be made of seamless steel pipe diameter is very small, the wall is very thin, good toughness, light. Cast iron, cheap, but the bottom of the strength, can only be used in low pressure occasions.
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:Heating system DN40 and DN32 welded steel pipe how to connect?
Welding: AC arc welding machine welding. Mode 1: apply to the medium of non demanding piping, DN40 steel pipe necking and DN32 steel pipe butt welding, or directly DN32 steel pipe into the DN40 internal welding. 2: the pipeline requirements apply to the inner wall of smooth transition, reducing short circuit welding for DN40x32 suppression of this mechanism are used for connection pipe seamless steel pipe high pressure pipeline connection, no special requirements, not commonly used welded steel pipe. Connection of mechanism fittings is not only costly, but not necessary unless special requirements are required!
Q:What does cathodic protection of steel tubes mean?
There are two ways of cathodic protection: sacrificial anode, cathodic protection and impressed current cathodic protection.Sacrificial anode: connect a living metal or alloy to a protective metal to form a galvanic cell. The active metal replaces the protected metal to lose electrons so that the protected metal is not corroded.
Q:What is lined pipe?
Is the coating of the inside of the pipe, such as pipe conveying sulfuric acid will corrode, corrosion, but soft plastic pipe, buried in the ground to wall thicker, then you can use the liner and characteristics of hard for using steel pipe laying, sheathed in the steel pipe into the thin plastic tube, it can transport the sulfuric acid,
Q:How are steel tubes represented?
Galvanized pipe: InchSeamless steel tube, welded pipe, nonferrous metal pipe, etc.: outer diameter x wall thickness
Q:How do you solder purple copper plate and steel tube?
When the copper and copper tube size is too large, argon welder welding, DC argon arc welding machine, of course, when DC argon arc welding welding belongs to welding, argon arc welding of brass with Wei Odin 204S welding, the argon arc welding wire for gas welding is not brass wire, this concept must be clear, the wire diameter of 2 80-120A, welding current parameters, if the copper thickness is relatively thick, with a red copper welding after welding preheating in advance.
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;
