Introduction to standard of API Steel pipe standard classification of API steel pipe and Difference API seamless steel pipe Standard

Anglo Petroleum Cato suddenly see this phrase, probably a lot of steel pipe industry people do not know what meaning. But referring to the API, its name is absolutely thunderclap, even if the rookie, can also say a Sanlai, API actually refers to the American Petroleum Association, its English full name is Anglo Petroleum Cato, built in 1919, is the first National Business Association in the United States, It is also one of the earliest and most successful standard-setting chambers in the world. As an international standard, it has long been engraved in the hearts of every steel employee. For me, the steel pipe personage, more is the pet has added, as long as has the opportunity to contact regarding the API the list, certainly studies attentively, has given the comfort I to its pursues sentiment.

API standards can be said to be a wide range, including pipe, pipe fittings, steel components, etc., may be involved in all aspects, if you do not carefully study will never understand its profound. Of course for me this steel pipe talent (oh, small blow), more should know more about the API pipe (seamless steel pipe, straight seam, alloy steel pipe, low-temperature steel pipe, spiral steel pipe, etc.) all standards.

API Spec Steel tube part is roughly two parts: oil casing and pipeline pipe.

Oil casing is mainly used in drilling process and completion of the shaft wall support, in order to ensure the drilling process and completion of the entire well after the normal operation. Oil casing can be produced by: API 5CT (similar to steel pipe GB gb/t19830) specifications include 60.3-508, steel grade for J55, K55, N80, L-80, P-110, C-90, C-95, T-95, etc., machinable buckle type has STC (short round buckle), LC (oblong buckle), BC (partial ladder buckle), VAM (partial ladder buckle), such as buckle type. This buckle type is not a simple connection, which has its own manufacturers of patented products, strict requirements.

A pipeline is a conduit for pumping oil, steam, and water from the ground into oil and gas industries. Pipeline pipe includes seamless pipe and welded steel pipe, its pipe end has flat end, with threaded end and socket end, its connection way has welding, hoop connection, socket connection and so on. Pipeline pipe can be produced to implement the standard: API 5L (similar to steel pipe GB GB/T9711.1/2/3) specifications include 219.1-2032, steel grade for gr.b, X42, X46, X52, X56, X60, X70, X80 and so on.
