1、Structure of Steel Pipe Q345 Descrption: 

    steel welded pipe is actually a cover term, covering a wide range of alloy and making them suitable for different attributes that are used in a very wide and large numbers of different industries. Stainless steel pipe is resistant to erosion, highly flexible, powerful, easy to use, and can be done in distinct approaches, which means that more and more stainless steel was used as a construction material for large-scale, high impact buildings. It can be molded, rolling, and it can create amazing shapes to make it perfect, It is used as experimental buildings, The use of steel pipe welding of large stainless steel covers other examples.

Q:What is the diameter of the steel tube DN20?
Stress: the nominal diameter is not the outer diameter of the pipe, nor the inner diameter of the tube. It is not the average value of the inside and outside diameter (the nominal diameter of the equipment refers to the outer diameter).
Q:What are the uses of welded steel pipes?
It is used to transport water, gas, air, oil and heating steam, and generally lower pressure fluid and other purposes of welded steel pipe. The wall thickness of the steel pipe is divided into ordinary steel pipe and thickened steel pipe. The end of the pipe is divided into non - threaded steel pipe (light pipe) and threaded steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2. The welded steel pipe for low pressure fluid transportation is used as the main pipe of galvanized steel pipe for low pressure fluid transportation except for directly conveying fluid
Q:How can seamless steel tubes be produced?
Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
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 tube with the tube with what is the difference?
At present there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.
Q:What kinds of steel pipe are divided into?
Welded pipe: also known as welded pipe, is made of steel or steel strip after bending forming, and then made by welding. In accordance with the form of weld is divided into longitudinal welded pipe and spiral welded pipeSpecifically refers to the use of welded steel strip or plate bending deformation of round, square shape after welded, surface jointed steel pipe. The welding steel billets is used in steel plate or strip. The welded pipe production process simple, high production efficiency, great variety, less capital equipment, but since the general strength is less than that of seamless steel.20 century 30s, along with the rapid development of high-quality strip rolling production and progress of welding and testing technology, and constantly improve the weld quality, varieties and specifications of welded steel pipe is increasing, and instead of the seamless steel pipe in more and more fields. Compared with welded steel seamless steel tube with low cost and high production efficiency.
Q:What does "buried steel pipe" 6*2SC100 mean?
The embedded steel pipe 6*2SC100 refers to a welded steel pipe with 2 pipe thicknesses of 6mm and a diameter of 100mm. SC pipe means welded steel pipe. Embedment means pre installation (burial).
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
SC in principle, it should be called water gas pipe, also called thick wall steel pipe;
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
