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.

How to detect the thickness of boiler tubes?

In industrial applications, boiler tubes are considered the "energy arteries" of equipment. They serve as vital components within boilers, forming the internal “veins” responsible for transporting high-temperature, high-pressure media. These tubes are primarily used for heating surfaces, steam lines, and other critical areas. They are widely applied in thermal power generation, industrial boilers, and centralized heating systems. The quality and performance of boiler tubes have a direct impact on energy conversion efficiency and operational safety.

Anti-corrosion measures for well casing pipes

In the oil industry, well casing pipes serve a vital role, much like blood vessels in the human body. These pipes are the primary conduit for transporting oil from underground to the surface, providing essential support for the proper functioning of oil wells. However, during actual use, both the inner and outer walls of well casing pipes are subjected to severe corrosion. The internal corrosion is particularly serious due to the presence of corrosive substances like hydrogen sulfide, carbon dioxide, and water in the oil and gas extracted from wells. Externally, well casing pipes face soil corrosion. Soil is a complex, multi-phase system composed of water, oxygen, microorganisms, and electrolytes that can "attack" the outer walls of these pipes. Therefore, implementing effective anti-corrosion measures is crucial to ensure the longevity and safety of well casings. This article outlines common methods used to prevent corrosion of well casing pipes in different environments.

Thick-walled seamless carbon steel pipe

Thick-walled seamless carbon steel pipes are produced using seamless processes like hot rolling, cold drawing, or extrusion. These pipes are characterized by a large wall thickness-to-pipe diameter ratio (typically wall thickness/outer diameter≥0.05), and due to the absence of welds, they offer more uniform structure and higher strength. This makes them ideal for high-pressure, high-load, or harsh environments.
