5CT K55 oilfield pipe can be found in the oil well drilling applications as casing for other pipes and tools. The K55 Oil And Gas Api Casing Pipe is supplied with short thread types and long thread types with appropriate couplings for fixture. The dimensions vary according to the use case. There are pipes of 2 3/8 inches, to 4 ½ inches outer diameters. The Grade K55 Oil Well Drilling Casing Pipe can range in length from R1 to R3 with 6.1m to 12.8m. There are different casing grades such as the J55, K55, N80-1 and so on. Each of these grades have different specifications. The API 5CT K55 Tubes range from 2.375 inches to 3.5 inches with plain end, EUE 8RD pipe end types. The diameter ranges from 4.5 inches to 9.625 inches for the API 5CT K55 casing and the end type can be STC, LTC or BTC. The material has carbon, manganese, molybdenum, chromium, nickel, copper, phosphorus, sulfur and silicon. Different grades of API 5ct Oilfield Tubing has different composition. There are only phosphorus and sulfur in addition to iron for the K55 Casing composition. The minimum yield strength of the pipes range from 379MPa to 552MPa. The minimum tensile strength of the API SPEC 5CT1988 is greater than 517MPa. The application of the pipes could be seen in petroleum, oil and gas, shipbuilding, aviation, food production, construction and many other industrial applications. The main purpose of the API 5CT K55 Casing Tubing is to provide an extra layer of corrosion resistant cover to applications. we are one of the supplier who provide cut to length pipe in all grade which saves your cost. Rexal Tubes is a API 5CT K55 Casing Tubing supplier who stocks pipes in all surface finish.
