Steel pipes are one of the most frequently and actively used types of rolled metal. It has found applications both in construction and the industrial sphere. Steel pipes are presented in a wide range of sizes, so choosing the optimal rental option is not difficult. But asme b16.11 forged fittings differs not only in the length and size of the section.
Steel pipe production: methods and features of products
For the manufacture of rolled steel, one of the three main methods is used:
- Welded
- Cast
- seamless
Seamless pipes are the most reliable and durable products that are widely used in various fields of industrial production. To obtain them, a steel blank is heated to a temperature determined by the technological process, after which a hole is created inside the workpiece.
Cold-deformed Stainless Steel 316 Pipe Fittings are produced by periodic rolling and drawing. This method of production of rolled products does not imply pre-heating the billet. It allows achieving the preservation of all the properties of steel raw materials in the finished product.
The method of cold rolling Flanges Manufacturer In India pipes can be carried out on mills of various types. One of the options is the impact on the workpiece with high pressure. As a result, the manufacturer receives the rental, which is particularly resistant to corrosion, with thin walls and a small diameter.
Welded pipes are also available in a wide variety of options. The most common are several types of pipe welding:
- high-frequency welding;
- submerged arc welding;
- DC welding;
- gas-electric welding.
The use of different methods for joining sheet blanks into a Forged Flange Manufacturers pipe allows one to obtain results characterized by a wide variety of properties. Thus, the method of gas-electric welding makes it possible to obtain pipes of the small and medium cross-section from high steel alloys.
Another popular modern method of joining Carbon Steel Flange is laser welding. Through the use of the method, it is possible to obtain pipes from high alloy steels of high strength.
According to Carbon Steel Flanges manufacturers in India welded pipes can be divided into two large classes - straight-seam and spiral-seam. The former is mainly used in the construction of trunk pipelines. They are presented in versions of measured and unmeasured lengths. Spiral seam rolling is most often used to create heating mains, main water and oil and gas pipelines.
Scope of steel pipes
Steel round and shaped pipes are widely used in a wide variety of industries.
Six main classes of products are distinguished:
1st class of steel pipes - standard type products used to create fences, supports, and conduct liquid and gaseous substances;
2nd class of rolled steel pipe - products used for transporting gas, oil and liquids are characterized by a high level of resistance to pressure;
pipes of the 3rd class can withstand the constant effects of high temperatures and pressure.
4th class of rolled pipe - products mainly used in the oil industry as casing, drilling and auxiliary elements;
5th-grade structural pipes are widely used in furniture manufacturing, in the construction industry, and mechanical engineering;
6th-grade steel is most often used in the engineering industry to produce parts exposed to high pressure.
