Product Description:

1Structure of API 5L  Seamless Carbon  Steel Pipe for Oiling Application: 

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.

2Main Features of API 5L  Seamless Carbon  Steel Pipe for Oiling Application:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
D108: refers to the outer diameter of 108mm;4: refers to the wall thickness of 4mm.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Fastener type steel pipe scaffold, fastener is the connection between steel pipe and steel pipe, and its form has three kinds, namely right angle fastener, rotating fastener, butt fastener
Q:What are the lengths of scaffold steel tubes?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
Q:How are steel tubes represented?
If you speak of steel pipe, if it is water. Gas transmission pipe, then it is said: nominal diameter refers to the inner diameter. The units are millimeters or inches. [for example, water pipes with phi 25. It means that the nominal diameter (diameter) is 25mm (or an inch) steel pipe.
Q:Is the PVC tube a plastic tube or a plastic tube?.
PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. Polyvinyl chloride (Poly, Vinyl, Chloride, PVC), it is obviously impossible to steel, we often say that iron and steel, the steel must be the main component of iron, Fe, inorganic. And PVC, polyvinyl chloride, is an organic substance. Therefore, PVC can not be called steel, and PVC constitutes a large number of substances, not confined to the pipe type.
Q:How to distinguish between steel pipe and spiral pipe material?
The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe, not seamless steel pipe, seamless steel pipe, welded seam, how can it be called seamless pipe?. Tell you a method: measurement of wall thickness, multi test several points, if each point, that is because it is cold drawn pipe, seamless pipe, hot rolling, wall thickness may% by sample.
Q:How big is the seamless steel tube of DN50?
This refers to the diameter of the steel pipe is 50 mm, DN50 steel pipe diameter is 60.3 mm, that is, 60.3 * 5 mm steel pipe
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Screw on the line, mainly anti-corrosion and insulation, seamless pipe caliber restrictions, so the price is high, with the most affordable screw can meet the requirements, 377 and 273 of the spiral 3920 yuan / ton, straight seam is about 4350
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
