  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.

  Difference between hot-dipped galvanized steel pipe and cold galvanized steel pipe

  old galvanized pipe and hot-dippedgalvanized pipe has a great difference in the operation mode. The zinc in hot-dippedgalvanizing is obtained at 450 degrees Celsius to 480 degrees Celsius, while the zinc in cold-galvanized steel pipe is obtained by electroplating at room temperature.

  Difference between carbon steel pipe and stainless steel pipe

  Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the shape of the vertical section. Variable section tube has conical tube, step tube, periodic section tube and so on.
