Seamless Steel Pipe
Seamless steel pipe (SMLS) is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section formed by drawing a solid billet over a piercing rod to create the hollow shell without a seam or a weld-joint, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. Seamless steel pipe can be cut, threaded or grooved. And the coating method includes black, red lacquer, varnish painting, hot dip galvanization, etc.
As a responsible manufacturer in China, TOPPER provided seamless steel pipes suitable for bending and flanging. The most advantage of our seamless steel pipes is the increased ability of withstanding higher pressure. It is widely welcomed by customers in industries of boiler and pressure vessel, automotive area, oil well, equipment components, ect.
The production of our seamless pipes is tightly regulated and all of the pipes we stock have been fully tested to international standards to ensure we only supply the highest quality products.

Fluid pipe, originally named waterproof pipe, is a type of pipes that move liquids around in a similar manner as transport pipes. These pipes are created by combining transport pipes with pipe sealant. Fluid pipes can be used to transport oil, fuel, water and lava to different locations. These pipes allow liquids to be transported into engines, tanks and oil refineries. When a pipe is not connected to anything, it will fill itself up instead of pouring the contents on the floor.
