ASTM seamless black steel pipe is made of round steel pipe not coated with zinc or paint base material after surface sandblasting to remove the surface of the oxide, floating rust and later spraying. Seamless black steel pipe Spec 40 is a very popular type of steel pipe, especially in the United States is very widely used for transporting natural gas and water to rural and urban areas, or for protecting power lines and carrying high pressure steam and air pipes. Generally used for gas distribution inside and outside the home, Wells and sewage systems, black steel pipes are also used in the oil and petroleum industry to transport large amounts of oil through remote areas.

1.What is seamless black steel pipe?

    ASTM seamless black steel tube is made of round steel tube not coated with zinc or paint base material after surface sandblasting to remove the surface of the oxide, floating rust and later spraying. The tube blank is directly perforated and rolled without welding line. Seamless black steel tubes are widely used in the United States to deliver natural gas and water to both rural and urban areas, or to protect power lines and pipes that carry high-pressure steam and air. Generally used for gas distribution inside and outside the home, Wells and sewage systems, black steel pipes are also used in the oil and petroleum industry to transport large amounts of oil through remote areas. Steel tube without seams along the perimeter of its cross section. According to different production methods, it can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe, pipe jacking, etc., all of which have their own technological provisions.

2.What is difference between ERW steel pipe and seamless black steel pipe?

    ERW steel tubes differ from seamless steel tubes in several ways ERW tubes are used to transport liquids such as fuel gases regardless of pressure, making it one of the most typical delivery tubes in the world Seamless tubing, on the other hand, is a square or rectangular shaped steel tube with no joints around it and a hollow cross section used for transporting liquids as well as fabricating structural and mechanical parts. ERW and seamless steel tubes in general are quite different in use due to their high bending and torque strength and incredible lightness The biggest difference between ERW pipe and seamless steel pipe is that THE ERW pipe has a weld, the same as the welded steel pipe, but the black seamless steel pipe does not have, and the welded steel pipe does not have in addition, the welding line of THE ERW pipe is the key to the quality of the ERW steel pipe. The more difficult the welding line of the ERW pipe is to identify, the higher the quality of the ERW pipe. Seamless-steel-pipe-for-USA.jpg       

    There are two methods to eliminate the weld: geometric seamless and physical seamless Geometric seamless inside and outside is to remove burrs, physical seamless is taking steps to make the parent metal and microstructure uniformity, seems to be more complicated to implement, but which can be compared with the processing technology of the ERW pipe, seamless steel pipe processing technology is much more simple There are two kinds of completely different processing technology: cold and hot rolling and hot rolling, cold drawing process is more complicated But, look from the exterior, the stainless steel cold drawn tubes, shorter than hot-rolled tube, cold drawn seamless stainless steel tube wall thickness generally smaller than hot rolled pipe wall thickness More important, need high temperature hot rolling process, reduces the resistance to deformation, so as to realize the large deformation In general, ERW pipe and seamless steel tube process there is a big difference, because of the different appearance In general, although ERW pipe and seamless steel pipe like welded steel pipe plays an important role in social construction, but ERW pipe and seamless pipe due to different appearance, different uses, progress is also different.

    How to identify the pipeline is ERW or seamless pipe? To identify whether a pipe is ERW or seamless, simply read the template on the side of the pipe if IT is ASTM A53,Type S means seamless; F type is furnace type but welded; Type E is resistance welding this is the easiest way to tell if a pipe is ERW or seamless.
