Oil Casing pipe
Petroleum casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well uses several layers of casing according to different drilling depths and geological conditions. Cement cementing is used after the casing is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. Casing can be divided into: conduit, surface casing, technical casing and oil layer casing according to the usage.

Oil Casing Specification Table
According to SY/T6194-96 "Petroleum casing", it is divided into two types: short threaded casing and its coupling, and long threaded casing and its coupling.
Oil casing with special threads is mainly used in wells where traditional API threads are not suitable. Traditional API threads have problems such as sealing and tensile strength. Traditional API threads have poor gas sealing performance. For wells containing hydrogen sulfide, carbon dioxide and chloride ions It is not suitable for wells in different positions, and special threads can effectively overcome these shortcomings. In addition, some high-grade steel pipes (such as Q125 and above steel grades) generally use special threads.

Introduction of Boiler Tube
Boiler tube is a kind of seamless steel tube. Boiler tube refers to a steel material with openings at both ends and a hollow section. The ratio of its length to the surrounding area is large. Dimensions (such as outer diameter or side length) and wall thickness indicate that there is a wide range of sizes, from small diameter capillaries to large diameter tubes with diameters of several meters. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.

Classification of welded pipe
Welded pipe is a common metal pipe, which is widely used in construction, machinery, automobile manufacturing, electronic equipment manufacturing and other fields due to its good corrosion resistance, strength and aesthetics. Generally, welded pipes can be classified according to different materials, processes and applications. Next, let's take a closer look at the classification of welded pipes.

What is the main difference between straight seam welded pipe and spiral welded pipe?
Due to the advanced production technology and high production efficiency, the production cost of ERW steel pipe is much lower than that of seamless steel pipe, and the price is also more advantageous.
