API 5CTJ55 K55 L80 N80 P110 Seamless Steel Tubing and Casing pipe

Petroleum casing is an important equipment for oil drilling. The thread surface of oil casing and coupling should be smooth. Burrs, tearing and other defects sufficient to cause thread interruption to affect strength and tight connection should not be allowed Steel Casing Pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity. Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors such as the interference-fit Permalok interlocking push-on joint. The steel casing pipe can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakesand rivers. Steel casing pipe protects one or many of various types of utilities such as water mains, gas pipes, electrical power cables, fiber optic cables, etc.  SurfaceTreatment Anti-corrosion Water Based Paint Standard API SPEC 5CT Steel grade:H40, J55, N80, N80Q, L80, L80-1, L80-9Cr, L80-13Cr, P110 etc O.D:114.3~508mm W.T:4.24-16mm Length:R1(4.88m-7.62m ), R2( 7.62m-10.36m), R3(10.36m-14.13m) packing details:Protection Caps on both ends and in bundles with steel strips and two tags as per export requirements Type of upset NUE, EUE, Plain end MOQ 10Ton Payment term T/T,L/C Delivery date:According to The Specifications And the Quantities Of Each Contract Application:Used as the architectural retainer for the walls of oil, gas wells Contact
