Product Description

API 5CT J55, K55, N80, L80, T95, P110 Q125 Oil Casing Pipe
Oil pipelines (also known as pipelines or pipelines) are composed of oil pipes and their accessories, and are equipped with corresponding oil pump units according to the needs of the process flow. They are designed and installed as a complete pipeline system for completing oil unloading and transportation tasks.
The oil pipeline system, also known as the pipeline system used to transport oil and petroleum products, is mainly composed of oil pipelines, oil stations, and other auxiliary equipment. It is one of the main equipment in the oil storage and transportation industry and the most important transportation equipment for crude oil and petroleum products. Compared with railway and highway oil transportation, pipeline oil transportation has the characteristics of large volume, good sealing, low cost, and high safety factor.
The pipe material of oil pipelines is generally steel pipes, which are connected to long-distance pipelines using welding and flanges, and valves are used for opening and closing control and flow regulation. Oil pipelines mainly have transportation processes such as isothermal transportation, heating transportation, and sequential transportation. The corrosion of pipelines and how to prevent corrosion are one of the important links in pipeline maintenance. Oil pipelines have become one of the main transportation tools for oil and still have considerable development potential in the future.
Oil casing is the lifeline to keep oil well running. Due to different geological conditions, the downhole stress state is complex, and the combined effects of tension, compression, bending and torsional stress act on the pipe body, which puts forward higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason, it may lead to a reduction in production of the entire well or even scrap it.

Pipe material and applicability
The main pipes used in oil pipelines are carbon steel pipes, which can be divided into seamless steel pipes and welded steel pipes according to their manufacturing process. Seamless steel pipes have the characteristics of high strength and multiple specifications, making them suitable for transportation of highly corrosive oil products or under high temperature conditions. Seamless steel pipes are divided into two types: hot rolled and cold drawn. Due to the fact that cold drawing can cause material hardening, corresponding heat treatment needs to be carried out according to the specific use of the pipe. Welded steel pipes can be divided into two types: butt welded steel pipes and unselected welded pipes. Due to the process characteristics of carbon steel pipes, they are prone to brittleness at low temperatures. Therefore, they are mainly suitable for normal temperature pipelines, and the service temperature of the pipes should not exceed 300 degrees Celsius. Generally speaking, the service temperature of ordinary carbon steel pipes is between 0 and 300 degrees Celsius. If high-quality carbon steel pipes are used, the temperature application range and relaxation can reach -40 to 450 degrees Celsius. The experimental pressure of steel pipes is generally 1.5 times the nominal pressure. When the temperature of the conveyed material does not exceed 200 degrees Celsius, the working pressure is the nominal pressure. When the temperature exceeds 200 degrees, the working pressure should be correspondingly lower than the nominal pressure
