The status of seamless steel pipes is very important in various fields, especially in applications that require high quality, high performance and high safety. Its unique advantages and versatility make it one of the materials of choice for many engineering and manufacturing projects. Here are its main advantages:
A cylindrical bar of steel is used to produce SMLS pipe. After heating the bar to a high temperature, a probe is put into the cylinder to produce a hole. The cylinder is then moved to rollers that shape it to the required diameter and wall thickness.
Due to superior mechanical strength and absence of seams, seamless steel pipe is frequently used as water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, and arched brick pipes. Specifically throughout the nuclear, natural gas, petrochemical, shipbuilding, and boiler sectors.
SMLS pipe is made using an extrusion method, which involves inflating a cylindrical metal tube through an opening in a die and then cutting it to lengths. The seamless pipe has no welded joint; thus, it has more strength and higher pressure capacity than equivalent size seamed pipes. The seamed pipe is made in a rolling process, which means that the welded joint is formed during production.
