Seamless Steel Tube
According to the production method, seamless tube divided into: hot rolled tube, cold rolled tube, cold drawing tube, extruded tube, top tube, etc. According to the shape of the section, the seamless steel tube is divided into: square, oval, triangular, hexagonal, melon seed, star shape, and a variety of complex shapes......Send Inquiry
Seamless tube is a kind of long steel with hollow section and no seams.
According to the production method, seamless tube divided into: hot rolled tube, cold rolled tube, cold drawing tube, extruded tube, top tube, etc. According to the shape of the section, the seamless steel tube is divided into: square, oval, triangular, hexagonal, melon seed, star shape, and a variety of complex shapes. Depending on the use, there are thick wall tube and thin wall tube. Seamless steel pipe is mainly used for petroleum geological drilling pipe, petroleum chemical cracking pipe, boiler tube, bearing tube and automobile, tractor and aviation with high precision structural steel pipe.
For different purposes, we will briefly introduce seamless steel pipes:
The seamless tube (GB/t8162-2008) is used for general structure and mechanical structure.
Seamless tube (GB/t8163-2008) for fluid delivery is generally seamless tube for conveying water, oil, gas and other fluids.
Low medium pressure boiler seamless tube (GB3087-2008) is used in the manufacture of various structural low intermediate pressure boiler superheated steam pipe, water pipe and locomotive boiler superheated steam pipe, pipes, small pipe and arch brick works of high quality carbon structural steel hot rolling and cold drawing (rolling) seamless tube.
High pressure boiler seamless tube (gb5310-2008) is a high quality carbon steel, alloy steel and stainless steel seamless tube for heating surface of water tube boiler for high pressure and above pressure. Fertilizer equipment with high-pressure seamless tube (GB6479-2000) is applicable to the working temperature for - 40 ~ 400 ℃, the working pressure of 10 ~ 30 ma chemical equipment and pipeline of high quality carbon structural steel and alloy steel seamless tube.
The oil cracking seamless tube (gb9948-2006) is a seamless tube for furnace tubes, heat exchangers and pipes for petroleum refineries.
The geological drilling steel pipe (yb235-70) is a steel pipe for the geological sector to carry out the core drilling, which can be divided into drill pipe, drill collar, core tube, casing and sedimentation pipe.
Diamond core drilling with seamless pipe (gb3423-82) is a seamless pipe for drilling rod, core rod and casing for diamond core drilling.
The oil drilling tube (yb528-65) is a seamless tube used to thicken or thicken the ends of oil drilling.
Ship with carbon steel seamless tube (GB5312-85) is the manufacturing of ship class I pressure piping, pressure piping Ⅱ, boiler and overheating for carbon steel seamless tube.Carbon steel seamless pipe wall temperature does not exceed 450 ℃, the alloy steel seamless tube wall temperature over 450 ℃.
The semi-axle tube (gb3088-82) is a seamless pipe of high quality carbon structural steel and alloy structural steel that can be used to make the axle tube of the car and the axle shaft of the drive axle.
High pressure tubing for diesel engine (gb3093-86) is a cold-drawn seamless pipe that can be used to produce high pressure of diesel injection system.
The hydraulic and pneumatic cylinder tubes are made of precision internal diameter seamless tubes (gb8713-88), which are used for the production of hydraulic and pneumatic cylinder cylinders with a precision internal diameter or cold rolled seamless tube.
Cold-drawn or cold-rolled precision seamless tube (gb3639-83) is used for mechanical structure, high dimensional accuracy of hydraulic equipment and high surface finish, cold drawing or cold rolled seamless tube.Choose precision seamless pipe manufacturing machinery structure or hydraulic equipment.
Structure with stainless steel seamless tube (GB/T14975-2002) is widely used in chemical industry, petroleum, textile, medical, food, machinery and other industrial corrosion of pipeline and components and parts are made of stainless steel hot rolling (crowded, expanding) and cold drawing (rolling) seamless tube.
Fluid conveying stainless steel seamless tube (GB/t14976-2002) is made of stainless steel for conveying fluids (extrusion, expansion) and cold drawing (rolling) seamless tube.
The non-seamless seamless tube is the general name of the seamless tube except for the shape of the cross section.According to the size of steel pipe cross section shape is different and can be divided into such as wall thickness seamless tube (code-named D), ranging from wall thickness seamless tube (code-named BD), variable diameter seamless pipe (code-named BJ).Heterogeneous seamless tubes are widely used in various structural parts, tools and mechanical parts.
Seamless steel pipe used in low temperature pipes (GB/T18984-2003) is used to level - 45 ℃ ~ 195 ℃ low temperature pressure vessel pipe and low temperature heat exchanger pipe with seamless steel tubes.
