Q:What does "buried steel pipe" 6*2SC100 mean?
This is the electrical drawings, such as water supply and drainage, HVAC is that DN, SC is the laying of electrical wiring, which is defined as threading pipe laying. 100 is the nominal diameter of the pipe, unit millimeters.
Q:How to identify stainless steel pipe and steel pipe?
The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:How are steel tubes represented?
Galvanized pipe: InchSeamless steel tube, welded pipe, nonferrous metal pipe, etc.: outer diameter x wall thickness
Q:What is the outer diameter of the steel tube?
The diameter of a steel pipe refers to the diameter of the steel pipe. The specifications of the steel tube is normal with diameter (diameter and thickness) said, for example 100MM outer diameter and wall thickness of 5MM tube is marked with 100*5.
Q:Difference between cold rolled steel pipe and common steel pipe
From the above point of view, the hot rolled steel pipe used in fluid transport, mechanical structure and other requirements of the size of the situation is not high, cold-rolled steel pipe used in precision instruments, hydraulic systems, pneumatic and other places demanding.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Small and medium-sized cold drawn and hot-rolled are many, large caliber is hot rolling, cold rolled spot less.
Q:Can stainless steel pipes spray black paint?
Yes, after painting, I usually touch hands and paint off in 2 years or so
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:How seamless steel tube is formed?
Hot drawing or cold drawing. The so-called cold is the billet from the thick wall tube is not heated, oil lubrication, with a steel sleeve inside, gradually elongated. Hot drawing is to make the billet tube red, do such work, generally thick wall applicable.
As the largest strip-steel production base in china, we can get the advantage of having the lowest goods transport cost. Our company covers an area of 80000 square meter, and transportation here is very convenient. We are mainly engaged in the manufacture and management of high frequency straight seam welded pipe. We now have 11 welded pipe production lines, with daily output of2800-3000 tons of welded pipe ranging from DN15--DN200 (1/2--8 inch),and the designed annual production capacity of 800,000 tons.
