API 5CT N80-Q Seamless Casing Steel Pipes

How is seamless steel pipe produced?

Hot rolling seamless pipe production process: 1. Introduction to seamless steel pipe The seamless steel pipe is a circular, square, rectangular steel with a hollow section and no seams around it. The seamless steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. The seamless steel pipe has a hollow section and is used as a pipe for conveying fluid. Compared with a solid steel such as round steel, the steel pipe has a lighter weight when it has the same bending and torsional strength, and is an economical […]

seamless steel pipe VS welded steel pipe

The difference between seamless steel pipe and welded steel pipe   The seamless steel pipe is made of round billet by hot rolling, cold rolling or cold drawing, and the pipe body is seamless. The welded steel pipe is made of flat steel plate and welded on the pipe body. Including ERW pipeline, LSAW pipeline, SSAW pipeline. ABTERSTEEL tells you the differences in raw materials, manufacturing processes, performance, appearance, dimensions, applications, cost prices, etc. for seamless and welded tubes. How to make seamless steel pipes. API 5L and ASTM seamless steel tubes are passed through a porous tube using steel […]

How to calculate the pressure capacity of seamless steel pipe

Seamless steel pipe calculate the pressure capacity The calculation method of the pressure bearing capacity of the seamless steel pipe is as follows. Let us choose a practical case to explain: DN=10MM, wall thickness is 3mm Let the tensile strength of the material be σ, the pressure be P, the outer diameter of the pipe D; the  wall thickness of the pipe δ=(P*D)/(2*σ/S)  where S is the safety factor; Because P is less than 7 MPa, S is selected as S=8; P is less than 17.5 MPa, S is selected as S=6; P is greater than 17.5 MPa, S is selected as […]

What are the risks of natural gas pipeline construction?

Abstract: The construction of long-distance transportation natural gas pipeline system is to achieve the purpose of long-distance pipeline transportation of natural gas, so that users along the line can obtain the required gas volume to meet the needs of users.       The construction of long-distance transportation natural gas pipeline system is to achieve the purpose of long-distance pipeline transportation of natural gas, so that users along the line can obtain the required gas volume to meet the needs of users. The procedures for pipeline construction are complicated. Long-distance pipeline systems are generally buried pipelines. Pipe trenches need to be dug. For […]

WATER PIPELINE JOINING METHODS AND PIPE INSTALLATION

JOINING METHODS AND PIPE INSTALLATION This data sheet describes the most common joining methods of steel water mains and the most important phases of installation. Applications • water mains • sewage pipes   1. Trench, foundation and filling The trench is dug wide enough, according to Figure 1, so as to have enough working space on both sides of the pipeline. If necessary, a levelling course is laid on the bottom of the trench. It is to be at least 150 mm thick measured from the exterior bottom of the pipe (See Fig. 2). The max. allowed grain size of the […]
