Q:What does "DN25 PN16" mean?
Steel pipe DN25, PN16, first of all, for this annotation: pipe DN class, often used in welded pipe, such as welded pipe DN25. PN16 means pressure, that is, 16 kilograms (1.6MPa).
Q:What are the advantages of PVC pipe and galvanized steel pipe?
This is different in different fields, in fact, the combination of PVC pipe and galvanized steel pipe becomes plastic steel pipe.The steel plastic pipe is in the internal and external combined with a layer of plastic pipe material and obtained a pipe, it has high mechanical strength, the steel pipe has the advantages of high impact resistance, and corrosion resistance of plastic material, has the advantages of high and low grade health fluid resistance and scaling.The steel pipe used by our company is produced by Benxi Steel, which is well known both at home and abroad. It has the advantages of low phosphorus, low sulfur and high mechanical performance. It can meet the requirements of users.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
15CrMo is a steel Pearlite Heat-resistant steel, has high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloy elements in steel, the tendency of hardening of steel is obvious, and the weldability is poor.
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:What's the difference between straight steel pipe and seamless steel pipe?
The welded pipe is made of rolled steel plates, and small ones are straight welded, and big ones are spiral welded. Because the welded pipe has weld, the mechanical performance of weld is poor, so its applicable range is limited, but its price is cheap. Significant difference is that there are welded pipe, seamless steel pipe is not, of course, the welded pipe treatment of good, layman do not see the difference.
Q:Where is a steel pipe casing usually used?
A straight tube of carbon steel sheathed on pipes and tubes and threading tubes to protect the joints from damage by electric welding. The purpose is to protect the wires and cables.
Q:Stainless steel tube, also known as why tube?
The longitudinal section can be divided into equal section tube and variable cross section tubeThe variable section tube has a conical tube, a stepped tube and a periodically cross section pipe, 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:Theoretical weight of 25*25*1.5 square steel tubes
The theoretical weight of 25*25*1.5 square steel tubes is 1.075kg/m.
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.
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.
