Structural smls steel pipe is mainly for structural service for example general construction structure, project scaffolds, mechanical processing and other structural applications. The common steel material are A53 Gr.B A106 Gr.B Q345 ST52 structural steel tubes.
Seamless Structural Carbon Steel Pipe Schedule 40 are widely used in below fields:
1) Petroleum, Chemical enterprise, superheater of boiler, heat exchanger
2) High temperature resistant transmission fluid pipe in power station
3) Ship with pressure pipe
4) The exhaust purification devices
5) Construction and ornament

Seamless structural steel pipe is divided into seamless steel pipe due to its applications are different. Structural smls steel pipe mainly used for general structure and mechanical processing, structure of hot rolling work of continuous casting slab or slab as raw material by step heating furnace, high pressure water descaling after entering the roughing mill, roughing expected by the cutting head, tail, and then into the finishing mill, and the implementation of computer control rolling and finishing after through laminar cooling and the winder becoming straight hair volume. Straight hair volume of head and tail often show tongue shape and fish shape, thickness and width accuracy is poorer and side often exists defects such as wave shape, folding and tower. The volume weight is heavier, coil diameter is 760 mm.(general pipe industry like to use to pass through the cutting head and cutting tail straight hair volume trimming and straightening, level off of multichannel time after finishing line processing cutting board or heavy volume becoming hot rolled steel plate, flat hot-rolled coil, slitting and belt and other products. Hot rolling finishing if volume after acid pickling to remove scale and greased the hot-rolled pickling plate volumes. Seamless structural steel pipe has a tendency to be local alternative cold rolling tube, price moderate, loved by the masses of users.Structural Carbon Steel Pipe stockiest
