Seamless Steel Pipe Manufacturer   Shanghai ShengQiu Materials Co., Ltd manufactures Seamless Steel Pipe in Carbon , Chrome Alloys , and Nickel & exotic grades. Seamless steel pipes are used because of their increased ability to withstand pressure, their excellent uniformity of shape, and their greater strength under loading. Although seamless pipe can sometimes be more expensive than welded pipe, this increased ability to withstand pressure allows you to use pipes that are thinner and lighter, which can help cut down on expenses. As a seamless steel pipe manufacturer, we can help decide which grade and type of steel pipe are needed for your project.   Common Applications for Seamless Steel Pipe The benefits of seamless pipes make it the preferred material in an array of commercial pipe applications, including shipbuilding, pipelines, oil rigs, oil field equipment, pressure vessels, machinery parts, and offshore rigs. An additional benefit of seamless pipes is ...

APILine Pipe is steel pipe used for the transmission of Oil, Gas and Petroleum Distillates. Line Pipes are manufactured as per specifications established by American Petroleum Institute (API). API 5L is a specification of API which defines the standard for the dimension, physical, mechanical and chemical properties of the steel. ShanghaiShengQiu Materials Co., Ltd manufacture the API line pipe required to transport natural gas, crude oil, liquid gasses from producing field to refinery. We manufacture line pipe as per API 5L standard which is supported by our good quality, committed delivery period, better service at a most competitive price.

  ASTM A106 seamless pipe is one of our most popular products.   ASTM A106 pipe is American standard material, including A, B, C three grades, the ingredients of A106 A is carbon and silicon, the tensile strength grade is 330 MPa. The ingredients of A106 B is carbon 、 manganese and silicon, the tensile strength grade is 415 MPa. The ingredients of A106 C is carbon, manganese and silicon components, the tensile strength grade is 485 MPa. ASTM A106 seamless pressure pipes (also known as ASME SA106 pipes) are commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers and ships. These pipes must carry fluids that exhibit higher temperature and pressure levels And gas. ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. Among them, cold drawn has higher dimensional accuracy than hot rolled, and the surface of hot rolled steel pipe is relatively rough. The large-diameter seamless steel pipe is hot-rolle...

  Generally speaking, the production process of thick-walled seamless pipe can be divided into two types: cold drawn/rolled and hot rolled. The production process of cold rolled seamless steel pipes is generally more complicated than hot rolled. First, the billet will be subjected to three-rolled continuous rolling, and then the sizing test will be carried out after extrusion. If the surface does not respond to cracks, the round pipes will be cut into one meter long. The next step is annealing process. Annealing needs to be pickled with acidic liquid. When pickling, pay more attention to whether there are a lot of bubbles on the surface. If there are a lot of bubbles, it means the quality of the steel pipe does not meet the standard. In appearance, cold rolled seamless steel pipes are shorter than hot rolled seamless steel pipes. The wall thickness of cold-rolled seamless steel pipes is generally smaller than hot-rolled seamless steel pipes, but the surface looks brighter than thic...

  The method of using acid solution to remove oxide scale and rust on the surface of steel is called pickling. Acids for pickling include sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid and mixed acids. The pickling process is to remove the surface oxide scale, and then go through lubrication treatment (carbon steel-phosphorous saponification, stainless steel-butter lime, copper and aluminum pipe-oiling, using the old process-copper plating), and then deep drawing processing. If the steel pipe is not pickled, there may be oxides and oil stains on the surface, and probably the phosphating solution cannot be able to remove them and the quality of phosphating will be reduced. In addition, in the manufacturing process of steel pipes, after many processes, if you are not careful, scars will appear on the surface of the steel pipes, which will reduce the corrosion resistance of the parts and affect the service life. In order to improve the corrosion resistance of the steel...
