How to distinguish between hot rolled and hot expanded seamless steel pipes

图片
 Hot rolled and hot expanded are two common processes for seamless steel pipes. How to distinguish between them?   Both hot expanded steel pipes and hot rolled steel pipes have strict requirements on the steel grades used in the manufacture of steel pipes. Hot expanded steel pipes are just a kind of steel pipe manufacturing process, which is to process small-diameter steel pipes into large-diameter steel pipes.   Hot expanded steel pipe: first of all, the outside surface is red and the inside surface is lead pink. The steel pipes to be hot expanded have strict requirements on the quality of steel grades. Usually, steel pipes with strong shrinkage properties are used, and a waste pipe finishing rolling process is used to expand the diameter of the pipe by cross-rolling or drawing. In this way, the steel pipe is thickened in a relatively short period of time to produce non-standard and special hot rolled pipes. This kind of hot expanded steel pipe has low cost and h...

The Main Application of Alloy Pipes(EN10216-2, ASTM A213, ASTM A179, ASTM A335)

图片
  The Main Application of Alloy Pipes Alloy pipes are mainly used to transport water, gas, natural gas, petroleum, and certain solid materials etc. Because the alloy pipe has a hollow section, it is widely used as a pipeline for conveying fluids and manufacture structural parts and mechanical parts, such as oil drill pipes, boiler pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. The alloy steel pipes can be used to manufacture ring-shaped parts and increase the utilization rate of materials, simplify the manufacturing process, save materials and reduce processing time, such as rolling bearing rings, jack sleeves, etc. Compared with solid steel such as round steel, the weight of alloy steel pipe is lighter when the bending and torsion strength is the same, so alloy steel pipe is a kind of economical cross-section steel. Shanghai ShengQiu can supply alloy pipes which are used for boiler and heat exchanger. Standard and Grade:  #E...

API5L Line Pipe

  API 5L Seamless Line Pipe Specifications The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe.  This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries.  API 5L is suitable for conveying gas, water, and oil.  Size range is limited only by manufacturer’s capabilities.   Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries.  The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2.  PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.   Grad...

ASTM A106 SEAMLESS PIPE

图片
  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...

How To Produce Thick Wall Seamless Steel Pipe

图片
  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 Necessity Of Pickling Seamless Steel Pipes

图片
  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...
