Description
Seamless Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 32 inch OD. Carbon Steel Seamless Pipes / Tubes Carbon steel is an alloy consisting of iron and carbon.
The percentage of carbon in the steel affects the hardness, strength of elasticity and ductility of carbon steel. Seamless carbon steel pipe or solid steel ingot is made of the capillary tube through the hole, then through the hot-rolled, cold rolled or cold call is made.
Seamless carbon steel pipe in China’s steel industry has an important position. Seamless carbon steel pipe material is a round tube, pipe cutting machine embryos to go through cutting about 1 m of length blank, and sent by conveyor belt furnace heating. Billet is fed into the heating furnace, the temperature is about 1200 degrees Celsius. Fuel is hydrogen or acetylene. Furnace temperature control is the key issue. Round tube came out to punch through the machine through air pressure.
Generally more common punch is tapered roll perforation machine, the punch high production efficiency, product quality, large diameter hole expansion, can wear a variety of steel. Perforation, round tube has been on three-roll cross rolling, rolling or extrusion. Squeezed off the tube after sizing. Sizing by high-speed rotary cone drill holes into the billet to form a tube. Pipe diameter by the sizing mill to determine the length of the drill diameter. After the pipe through the sizing into the cooling tower, cooling by water spray, steel after cooling, should be straightening.
After the steel belt sent by straightening metal testing machine (or pressure test) for internal testing. If the pipe internal cracks, bubbles and other problems will be detected. After the pipe but also through strict quality control manual selection. Steel quality, the use of spray paint numbers, specifications, production lot number. By a crane into the warehouse.

Painting & Coating
Surface treatment of steel pipe: In order to improve the service life of oil pipeline, surface treatment is usually carried out to facilitate the firm combination of steel pipe and anticorrosive coating.Common processing methods are: cleaning, tool derusting, pickling, shot blasting derusting four categories
1 cleaningGrease, dust, lubricant, organic matter adhered on the surface of steel pipe, usually using solvent, emulsion to clean the surface.However, the rust, oxide skin and welding slag on the surface of the steel pipe cannot be removed, so other treatment methods are needed.Tool rust removalSteel pipe surface oxide, rust, welding slag, can use steel wire brush to clean and polish the surface treatment.Tool derusting can be divided into manual and power, manual tool derusting can reach Sa 2 level, power tool derusting can reach Sa3 level.If the surface of steel pipe is attached with a particularly strong oxide skin, it may be impossible to remove the rust with the help of tools, so we need to find other ways.
3 pickling Common pickling methods include chemistry and electrolysis.But only chemical pickling is used for pipeline corrosion protection.Chemical pickling can achieve a certain degree of cleanliness and roughness on the surface of steel pipe, which is convenient for subsequent anchor lines.Usually as a shot (sand) after reprocessing.
4 shot blasting for rust removalBy high power motor drive the high-speed rotating blades, steel grit, steel shot, segment, minerals and other abrasive wire under the action of centrifugal force on steel pipe surface spray and mass ejection, thoroughly remove rust, oxides and dirt on one hand, on the other hand, steel pipe under the action of abrasive violent impact and friction force, to achieve the required uniform roughness.
Among the four treatment methods, shot blasting and derusting is an ideal treatment method for pipe derusting. Generally, shot blasting and derusting are mainly used for inner surface treatment of steel pipe, and shot blasting and derusting are mainly used for outer surface treatment of steel pipe.
