A large number of pipes are needed in the field of the oil, gas and chemical industries. Oil well pipe is mainly used for oil and gas production, pipeline pipe is primarily used for long-distance oil and gas transmission pipeline, stainless steel pipe and titanium alloy pipe are typically used for oil refining.
The transportation system of transmission pipeline has the characteristics of a large investment and long service time. As the most important component of the pipeline system, the steel pipe and pipe fittings (elbows, tees, etc.) must ensure high quality. Aikor can provide professional and qualified inspectors to provide full process inspection services for manufacturing LSAW, DSAW, SSAW, ERW, seamless, induction heating elbow and fitting, and lined or clad pipes.
The safety, reliability and service life of oil well tube (OCTG) are directly related to the life of oil well and to the benefit of the oil field. Aikor can provide the entire process with inspection services of casing, tubing and drill string components (drill pipe, drill collar, etc.) according to the requirements specified by customers.
Aikor has an excellent team from China and abroad to provide technical support in material selection, manufacturing process audit, progress control and major quality issues in handling.
