API SPEC5CT-1999 (Bushing and Tubing Specification), is a generic version of the American Petreleum Instiute ("API") compiled and distributed worldwide. Including: casing: from the surface into the drilling well, as the lining of the pipe wall, the pipe between the connection through the coupling. The main material for the J55, N80, P110 and other steel grades, as well as anti-hydrogen sulfide corrosion C90, T95 and other steel grades. The low steel grade (J55, N80) for the welded steel pipe. Tubing: Pipe inserted into the casing from the ground surface up to the reservoir. The pipes are connected by the coupling or the whole. The role of the pumping unit is the role of oil and oil pipelines to the ground. The main material for the J55, N80, P110, and hydrogen sulfide corrosion C90, T95 and other steel grades. The low steel grade (J55, N80) for the welded steel pipe.
API SPEC 5L-2000 (Pipeline Specification), compiled and published by the American Petroleum Institute, is used all over the world.
Pipeline: is the oil, gas or water out of the ground through the pipeline to the oil and gas industry enterprises. Line pipe, including seamless and welded pipe two, the pipe end with a flat end, with a threaded end and socket end; the connection for the end of the welding, coupling, socket connection. The main material of the tube is B, X42, X56, X65, X70 and other steel grades.
Alloy pipe (Alloy pipe) is a seamless steel pipe, alloy pipe is divided into structural seamless pipe and high pressure heat-resistant alloy pipe. Mainly different from the alloy tube production standards and its industry, the alloy tube annealing quenched and tempered to change its mechanical properties. To achieve the required processing conditions. Its performance than the average variable high value of seamless steel pipe, alloy tube containing more Cr chemical composition, high temperature, low temperature, corrosion-resistant properties. Common carbon seamless tube does not contain alloy composition or alloy composition is very small, alloy tube in petroleum, aerospace, chemical, electric power, boilers, military and other industries more widely used due to changes in the mechanical properties of the alloy tube to adjust.
