An SMLS pipe is a pipe that has no welding seam. A seamless piping design can create several benefits such as increased strength and a smooth interior finish that is rust-resistant. Commercial, industrial, and residential customers will typically choose seamless pipes for their durability in various applications.

What is SMLS Pipe?
An SMLS pipe is a pipe without any welded connections. Idealistically, the seamless pipe will be a solid metal pipe with each end welded directly to another pipe.
Typically, a seamless pipe begins as a billet, a solid cylindrical hunk of steel. The billet is pierced in the center with a mandrel while it is still hot. The hollow billet is next rolled and stretched; this operation minimizes internal tensions and eliminates burrs from the interior of the pipe. After being rolled and stretched, the pipe is warmed to produce exact dimensions and thoroughly harden its surface.
SMLS steel pipe is widely used in engineering and construction; it is a hollow steel strip with no seams; it is primarily used to transport liquids through pipelines; it has a distinct appearance and is made of a heavy type of steel; it has a high resistance to corrosion and is resistant to general corrosion. This quality allows seamless steel tubes to have a longer lifespan, but what is essential is that they are extremely pure and free of contaminants.
Seamless steel pipe has a high mechanical resistance, regardless of how high the temperature is, seamless steel pipe is uninterested in impact, it is installed and the other pipe is the same, it can replace other piped water and other fluids.
Where SMLS Pipes are Used?
Due to superior mechanical strength and absence of seams, SMLS pipes are 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.

How is SMLS Pipe Made?
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.
What is the Difference between SMLS Pipe and Seamed Pipe?
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.
