Seamless Steel Pipe

Seamless pipe made of a single piece of metal with no seams on the surface is called a seamless steel pipe. According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe, and the like. According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

Non-standard SMLS pipes

Non-standard seamless steel pipes (non-standard smls pipes) refer to pipes whose dimensions, materials, or performance characteristics do not fully comply with existing public standards such as GB/T 8162 "Seamless Steel Pipes for Structures" or GB/T 8163 "Seamless Steel Pipes for Transporting Fluids". These pipes are primarily designed to fill the gaps where standard specifications fall short in real-world applications. In practice, non-standard smls pipes are essential in scenarios where national standard products cannot meet specific requirements — such as special engineering projects, equipment repairs, customized products in small batches, or material and process testing. For example, in the manufacture of large, specialized equipment, pipes with unique dimensions or materials may be required. Non-standard pipes can effectively fulfill these special needs.

Well casing pipe features applications and functions

In the oil and gas industry, well casing pipe serves as the backbone of drilling operations, playing a crucial role in maintaining the integrity and stability of oil wells. Multiple layers of casing are required for each well, depending on the depth of drilling and geological conditions. Acting like a sturdy framework, casing pipes ensure safe drilling by preventing wellbore collapse caused by complex underground forces. Even after drilling is complete, the casing continues to safeguard the well, enabling sustained and efficient production over time.
