Large-diameter thick-walled steel pipe is mainly used for mechanical processing, production of cylinders and other places! The outer diameter of large-diameter thick-walled steel pipe is usually more than 200mm, and the steel pipe whose wall thickness exceeds 20mm can reach a maximum diameter of 1220mm and a wall thickness of 80mm.
The production process of large-diameter thick-walled steel pipe generally includes hot rolling, hot coiling, casting and other production methods! Large-caliber thick-walled steel pipes are more common in double-sided submerged arc welding production processes. The products have been subjected to multiple procedures such as bending, welding, welding, welding, straightening, and flat-head welding to meet the requirements of the American Petroleum Institute. Large-caliber thick-walled steel pipes are mostly used in the construction of large-scale steel structures and serve as main support components such as bridge piling, subsea piling, and high-rise building piling. The material is generally selected Q345B, Q345C. Q345D, Q345E will also be used in lower temperature areas.
Diamond Grinding Wheels revolutionized the abrasives industry. Through the use of a unique core bonding technology, these grinding wheels last longer and outperform with far less sparks and odor than traditional grinding wheels for fast cutting, back cutting, gully grinding and bead finishing.
Diamond grinding wheel also have different types , such as electroplated diamond grinding wheels, vitrified diamond grinding wheels, resin bond diamond grinding wheels, vacuum brazing diamond grinding wheels. There are four kind of bonding processing methed. Each type has their unique special advantages for different type of working materials.
Kemei produce all four types fo diamond and CBN Grinding Wheels. Please contact us for more information and better grinding solutions.
