Product Description

The seamless steel pipe is made of a whole piece of metal and has no seam on the surface.According to the production method,seamless pipes are divided into hot tube, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking, etc. According to the cross-sectional shape, seamless steel pipes are divided into circular and special-shaped pipes. Special-shaped pipes have many complex shapes, such as square, oval, triangle, hexagon, melon seeds, star and finned pipes.Seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemical industry, boiler tubes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.

Usually made of high-quality carbon steel, such as 10, 20, 30, 35, 45, etc., such as low-alloy steel, such as 16Mn, 5MnV, etc., etc., made of hot-rolled or cold-rolled steel, such as 40Cr, 30CrMnSi, 45Mn2 , MOMnB, etc. Mainly made of low carbon steel, Buch as0 and 20 seamless pipes. The seamless machining of medium carbon steels such as 45cr and 40Cr is used to make mechanical parts such as car and tractor parts. Seamless steel pipes are generally used to ensure strength and flattening tests. Hot-rolled steel pipes are in a hot-rolled state or a heat-treated state. A combination of cold and heat for heat treatment. Low and medium pressure boiler seamless steel pipe: used to manufacture various low and medium pressure boiler booster steam pipes, water supply pipes, water wall pipes and other locomotive boiler superheated steam pipes, arch brick pipes, small pipes, etc.

Shandong Jianlong Iron and Steel Co., Ltd. is a company with more than 10 years of experience. We are located in Liaocheng, one of the largest steel producing areas in China. We have our own production plant. We also deal in prepainted steel coil, corrugated roofing sheet and carbon steel coil, etc. Welcome to purchase.

Product Specification

Name	Seamless Steel Tube
Length	MAX 18000
OD	6.0-114.0mm
Delivery Condition	Annealed, Normalized, Normalized and Tempered
Surface treatment	Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting
Application	For high, middle, low pressure boiler and pressure purpose. Used in heat exchangers and boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall.
Standard & Grade	ASTM, ASME, A/SA 192, 209, 210 and 213 specifications and all associated grades. EN 10216, DN 17175, BS 3059, JIS 3461 – 3462
Approvals	ISMT is ISO 14001, ISO/TS 16949:2002, and OHSAS 18001 approved. In addition we hold approvals from all major national and international official authorities, customers, and third party certification agencies.
