Product Description:

1、Structure of Seamless Pipe 20# API5L: 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.


2、‍‍Main Features of the Seamless Pipe 20# API5L:

• High manufacturing accuracy

Q:Is steel pipe made of profiles?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:How to distinguish seamless pipe and welded pipe?
Most of the welded pipe is six meters, the pipe has obvious welding marks, and seamless pipe wall without welding marks
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Galvanized steel pipe wall thickness weight outer diameter 108mm 4mm 6 meters in length is about 10.26*6*1.06=65 kg.Kg/m= (outside diameter mm-, wall thickness mm) * wall thickness mm*0.02466= (108-4) *4*0.02466=10.26 kg / MBecause of galvanizing, the weight is heavier than that of ordinary welded pipe 3%~6%.
Q:Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?
SC galvanized steel pipe, its pipe wall thickness, generally 20 steel pipe in 2.2-2.8mm. Also, we often refer to tap water galvanized steel pipe.MT wire pipe, its pipe wall is thin, generally 20 steel pipe in 1.5-2.2mm.
Q:What quota is reserved for buried DN20 steel pipe?
It is an embedded sleeve control sub item, if the reserved hole, then there is no need to cover, special subject structure adjustment factor of the cost of the water supply and drainage engineering, water supply and drainage engineering he is buried under the charge.
Q:Material of welded steel pipe
GB/T3092-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is: Q235 grade a steel.GB/T14291-1992 (mine fluid conveying welded steel pipe). It is mainly used in mine pressure air, drainage and vertical seam gas welding pipe. Its representative material is Q235A, B grade steel.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
The difference between hot rolled seamless steel tube and cold rolled seamless steel tube:1) cold-rolled seamless tubes tend to be of small diameter, and hot-rolled seamless tubes are often of large diameter.2) the accuracy of cold-rolled seamless steel tube is higher than that of hot-rolled seamless steel tube, and the price is higher than that of hot-rolled seamless steel tube.
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;
Q:What materials are used in scaffolding pipes?
The bamboo scaffold board made of bamboo or bamboo.
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.
