The vast majority of welding methods of pipeline products can be divided into electric resistance welding (ERW), longitudinal submerged arc welding (LSAW), spiral submerged arc welding (SSAW). And LSAW can be divided into UO (UOE), RB (RBE) and JCO (JCOE) ...

In the last article,we talked about different welding types.MIG and TIG are two important welding types.What the difference between them? Tungsten inert gas (TIG) welding S.no MIG Welding TIG welding 1. MIG stands for Metal Inert Gas Welding. It is al ...

In steel pipeline industry,we often hear of seamless or welding fittings.Especially for big sizes fittings,the welding is necessary in the production.What does welding mean?And why is it important? Welding is a material joining process performed by applica ...

The main types of welding used in industry are commonly referred to as Mig welding, Arc welding, Gas welding, and Tig welding. Mig Welding – GMAW or Gas Metal Arc Welding More commonly called MIG welding this welding type is the most widely used and perhap ...

Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from ...

Eddy current array (ECA) is a nondestructive testing technology that provides the ability to electronically drive multiple eddy current coils,which are placed side by side in the same probe assembly.Each individual eddy current coil in the probe produces a ...

Penetrant method of non-destructive testing is dedicated to detecting surface defects invisible to the naked eye. It is based on use of capillary properties of liquids (namely, on capillary penetration of special indicator liquids inside defects). This met ...

Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between ...

Magnetic particle inspection (often abbreviated MT or MPI) is a nondestructive inspection method that provides detection of linear flaws located at or near the surface of ferromagnetic materials. It is viewed primarily as a surface examination method. Magn ...

To assure weld quality, all welds should be inspected. In some cases, the inspection involves nothing more than a visual examination by the welder. However, a good-looking weld does not always ensure internal quality, so it’s important to conduct som ...

When the stainless steel pipe fittings or forged steel flange products are manufactured in our factory,we should keep attention to the intergranular corrosion of such piping products.The microstructure of metals and alloys are made up of grains,and they ar ...

The service life of the pipeline is directly related to the anticorrosion construction of the pipeline, so the measures for the anticorrosion construction of the pipeline should be optimized, and the construction quality and key points should be controlled ...

To an outsider, pipes and tubes may seem like they should be synonymous. To a marine engineer, the measurements, standards and language used to distinguish the two are quite different. In fact, differences in nomenclature and measurements could cause quite ...

In Oil & Gas industries. Let us explore the similarity and differences between piping and pipeline. Piping and pipeline both used to transport various liquids, gases and sometimes slurry and powder material. Straight VS Complex The pipeline is series o ...

Steel pipe is a kind of common construction material in our daily life such as welded steel pipe. Therefore, manufacturers who expertise in steel pipe production are various. In these factories, their production ability is different, so the steel pipe qual ...

It is a steel plastic composite steel pipe which is based on steel pipe and welded with a plastic anti-corrosion layer on the inner surface of steel pipe (bottom pipe) through spraying, rolling, soaking and suction processes or welded with plastic anti-cor ...

Polyurethane thermal insulation pipeline has been developed rapidly as a kind of excellent thermal insulation material, and its application scope is also more and more extensive. Moreover, because of its simple construction, energy-saving and anti-corrosio ...

Steel plastic composite pipe, the product is seamless steel pipe, welded steel pipe as the base pipe, the inner wall is coated with high adhesion, anti-corrosion, food grade health type polyethylene powder coating or epoxy resin coating.It has good corrosi ...

How to purchase high quality steel pipe? First,you need to cheek the surface of the steel pipe.The color is selected to be uniform and uniform,the inner and outer walls are smooth and flat,and there are no bubbles,depressions or impurities, which affect th ...

Steel pipes are a very important building material, whether it is transporting fluids and powdered solids, exchanging heat, making mechanical parts and containers, manufacturing building structures, pillars and mechanical supports, or seeing home furniture ...
