 Oil casing pipe is also called special oil pipe, which is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It includes oil drilling pipes, oil casings, and oil sucking pipes. Oil drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing is mainly used to support the well wall during the drilling process and after the well completion, so as to ensure the drilling process and the normal operation of the entire oil well after the well completion. The oil pipe mainly transports the oil and gas at the bottom of the oil well to the surface. Downhole casing string is the only and permanent channel for exploiting oil and gas resources, and plays a vital role in protecting the borehole wall and separating different pressure layers. Oil pipes are mainly used for the drilling of oil and gas wells and the transportation of oil and gas. Therefore, it is particularly important to ensure the quality of ...

 We know that steel pipes can be used for many aspects, such as structural application, piling pipe, line pipe, liquid transportation, casing, tubing, boiler tube, mechanical pipe, cylinder pipe, drill pipe, etc. Then do you know which kind of steel pipes can be used for liquid transportation? Let’s start from ERW steel pipe. ERW Steel pipe can be used for low pressure liquid transportation. ERW steel pipe is widely used for oil and gas transmission, tubing and casing, sewage treatment, etc, but as erw steel pipe has a weld seam, so is not so suitable for high pressure liquid transportation. SSAW steel pipe can also be used for liquid transportation. SSAW steel pipe is widely used for penstock pipe, and in 2017, Xinyue Steel Group has a SSAW penstock project in Uganda. But also per its manufacturing process, it also not suitable for high of cold temperature and high pressure working condition. LSAW steel pipe is widely used for pipeline project. LSAW steel pipe is widely applied in...

 In the process of heat treatment of seamless pipes, various defects will occur due to improper process measures or various other factors, and the existence of these defects directly affects the performance of steel pipes. 1. Crack Heat treatment cracks mainly include quenching cracks, tempering cracks and grinding cracks. When heating some large-sized steel parts and alloy billets, if the cooling rate is too fast during the cooling process, cracks will easily occur. Seriously, there will be cracks in the section, and once the workpiece is cracked, it cannot be repaired, and it can only be re-processed. Therefore, during the heat treatment process, try to achieve uniform heating and correct heating, select the appropriate cooling medium and cooling method, and select the correct method for immersing the workpiece in the quenching medium and the direction of the workpiece. 2. Overheating Overheating refers to the phenomenon that the grains are significantly coarsened due to excessiv...

 Welded steel pipes from Xinyue Steel Group can be devided into below classifications: Spiral steel pipe: Process: Spiral Submerged- Arc Welded Steel Pipe Application: Used for low pressure liquid delivery, such as water, gas, and oil; construction and piling. Product Range: OD:219.1mm –3048mm WT: 5.0mm-30mm LSAW steel pipe: Process: LSAW - UO(UOE)?RB(RBE)?JCO(JCOE) DSAW -Double Submerged arc welded Application: Used for low pressure liquid delivery, such as water, gas, and oil. OD:355.6mm– 1626mm WT: 8.0mm-50mm ERW Steel Pipe: Process: ERW : Electric Resistance Welded pipe HFI: High Frequency Induction weld pipe EFW: Electric Fusion Welded Pipe Application: Used for low pressure liquid delivery, such as water, gas, and oil. Oil drilling and machinery manufacturing, etc. Out Diameter: 21.3mm -660mm Wall Thickness: 1.5mm-22.2mm http://www.tjxysteel.com/news/Type-and-application-of-welded-steel-pipe-245.html

 Tianjin Xinyue Steel Group is a professional steel pipe mills from Tianjin, China. If you are familier with Chinese steel market, you may know that Tianjin is the base of Chinese steel mills. ERW steel pipe is Xinyue Steel Pipe’s main product. Xinyue can provide outer diameter size from 21.3mm to 660mm. Wall thickness size from 1.5mm to 22.2mm. Main usage for Electric Resistance Welded Steel Pipe are as below: 1. low pressure liquid delivery 2. water, gas, and oil transportation 3. Oil drilling 4. machinery manufacturing, etc. In some countries, people also name ERW steel pipe as High Frequency Induction weld pipe(HFI), Electric Fusion Welded Pipe(EFW),etc. Most common seen standard and steel grade: API 5L : GR B, X42,X46, X56, X60,X65,X70 ASTM A53: GR A, GR B, GR C EN: S275, S275JR, S355JRH, S355J2H GB: Q195, Q215, Q235, Q345, L175, L210, L245, L320, L360- L555 Surface Treatment: Fusion bond Epoxy coating, Coal Tar Epoxy, 3PE, Vanish Coating, Bitumen Coating, Black Oil coating or...

 SSAW, which is short for spiral submerged arc welded, is the steel pipe with spiral weld seam that using steel coil as raw material, extrusion forming under normal temperature, and welding by double-sided submerged arc welding technology. We can devide SSAW steel pipe per its usage: The first kind of SSAW steel pipe is used for pressurized fluid transportation is mainly used for conveying oil and natural gas pipeline. The second kind if 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. The third kind is 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 spiral submerged arc welded steel pipe is generally divided into: mini...
