Seamless steel pipe products and specifications are very numerous, and their performance requirements are various. All of these should be distinguished according to user requirements or changes in working conditions. In general, SMLS pipe products should be based on cross section shape, production method, material quality, connection mode, plating characteristics and classification.
The cross-section shape of SMLS pipe can be divided into round steel pipe and special-shaped steel tube.
The special-shaped steel pipe is a kind of steel pipe with various non circular sections. There are: square tube, square tube, elliptical tube, flat tube, semicircle tube, six corner tube, six corner tube, one side six corner tube, equilateral triangle tube, five corner flower tube, octagonal tube, convex tube, double convex tube. Double tube, multi concave tube, melon tube, flat tube, diamond tube, star tube, parallel quadrilateral tube, ribbed tube, drip tube, inner fin tube, stranded tube, tube and multi-layer tube.
SMLS pipes are divided into section steel and cross section steel according to their longitudinal profile.
SMLS pipes refer to the cross section shape, inner and outer diameters and wall thickness of pipes along the length, such as periodic or non periodic changes of steel pipes. They are: conical tube, tapered tube, trapezoidal tube, trapezoidal tube, circulating pipe, bellows, radiator tube and double barrel.
