SSAW Pipe

Zimbabwe, a landlocked country in southern Africa, is a rapidly growing economy with an increasing demand for high-quality steel materials. Xinyue, a leading manufacturer of steel tubes and fittings, has been providing the Zimbabwean market with reliable and durable steel products that meet the industry’s needs. Xinyue’s steel tubes are designed and produced using advanced technology and top-grade materials, making them ideal for a wide range of applications. From oil and gas pipelines to construction projects, the company’s steel tubes are versatile and dependable. Their fittings, on the other hand, are manufactured to meet the highest quality standards and can be customized to meet specific requirements. The Zimbabwean steel market is driven by a robust construction industry, mining operations, and infrastructure development. With the government’s focus on infrastructure development, including road construction and expansion of energy generation facilities, the demand for high-qualit...

    With the continuous increase in the delivery pressure and steel grade of oil and gas pipelines, the requirements of ERW steel pipes for oil and gas transportation are also increasing. The number of ERW steel pipes used in submarine pipelines is relatively large, such as some oilfield group development projects and natural gas development projects. ERW steel pipe is formed by continuous roll forming of hot-rolled coils, which uses the skin effect and proximity effect of high-frequency current to generate resistance heat at the edges of the coils and cause metal melting. Pressure welding is performed under the action of squeeze rollers. Its characteristics: high welding speed, because the current energy is highly concentrated in the welding zone, the heating speed is extremely fast, so the welding speed is very high, the welding speed is generally between 10 m / min and 45 m / min; the heat affected zone is small, because the welding speed is high , The workpiece has a stron...

　　Inner coating can greatly improve pipeline capacity. It can prevent corrosion and reduce the role of the pumping costs. Improving gas flow within the coating technology development update has become the main methods of transport in major companies to increase the amount. It can significantly reduce the friction between the gas and the tube wall which is the basic function of the inner coating technology. The friction caused by the tube at the factory of its inner surface is rough, the use of the inner pipe wall coating becomes smooth, the friction between the gas and the wall becomes small. It will accelerate the gas flow rate, and the cost of pumping the respective compression lower. 　　The coating into a file (dry film thickness of 80 ~130 um) coated on the inner wall of the tube. Epoxy resins are currently the most widely used in the coating material, a lot of in-service pipeline are in use. The inner coating should have a certain adhesion, porosity, elasticity, chemical resistan...

　　 SSAW steel pipe is the steel pipe with spiral seam that using strip coil as raw material, extrusion forming under normal temperature, and welding by automatic Double wire double-sided submerged arc welding process. Classification of SSAW steel pipe includes: 　　1. SSAW steel pipe (SY5036-83) used for pressurized fluid transportation is mainly used for conveying oil and natural gas pipeline. 　　2. SSAW steel pipe (SY5038-83) used for pressurized fluid transportation, it is welded with high-frequency welding method. The loading capacity of it is powerful, the plastic is good, and it is easy to weld and machine shaping. 　　3. SSAW steel pipe (SY5037-83) used for general low-pressure fluid transmission, it is welded with double-sided automatic submerged arc welding method or one-side welding method, it is mainly used for water, gas, air and steam and other general low-pressure fluid delivery. 　　Now general standards for SSAW steel pipe is generally divided into: SY/T5037-2000 (min...

　　In the construction and repair of gas pipeline welding operations, sometimes magnetic blow phenomena affect the welding process. 　　The formation of magnetic blow pipe metal present in remanence results. Typically, the remanence is divided into two kinds of induction magnetic and processes magnetic. Often produce magnetic induction pipe part in the factory, such as: metal smelting, using electromagnetic crane for loading and unloading, pipe parked in a strong magnetic field, the magnetization method with complete nondestructive inspection, pipe placed close to power lines and so powerful. Magnetic assembly processes often produce during welding operations and the use of a magnetic holder, clamps and pipe welding with DC, such as: prolonged contact with the DC power supply connected to electrical conductors, bare wire welding clamp and pipe segment or short-circuit and so on. 　　When the welding magnetic seamless steel tube, often can see the difficulties of arc ignition, arc burnin...
