Analysis of performance index of stainless steel strip

Analysis of performance index of stainless steel strip

304 stainless steel belt is a universal stainless steel material, and its rust resistance is stronger than that of 200 series stainless steel materials. Stainless steel strip is mainly a narrow and long steel plate produced to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. In fact, many mechanical parts are under the action of working cycle loads, and the parts will fatigue under this premise. Stainless steel strip is mainly a narrow and long steel plate produced to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Other profiles of special-shaped steel pipes and stainless steel strips are also required.

1. In the process of welding low-pressure working fluids for transportation, steel pipes are also called general welded pipes, commonly known as black pipes. It is a welded steel pipe used for general low-cost pressure calculation fluids and other main purposes for enterprises to transport water, gas, air, oil and heating steam. The wall thickness of the steel pipe is divided into a common steel pipe and a thickened steel pipe; the form of the pipe end can be divided into an internal non-threaded steel pipe and a threaded steel pipe. The specification of the steel pipe is implied by the nominal diameter, which is an approximation of the inner diameter. It is customary for us to use inch hints, such as 11/2 and so on. In addition to direct investment for social transportation of fluids through welded steel pipes for low-pressure control fluids, they are also largely used as low-pressure system fluids as the original pipes of welded steel pipes for transportation.

2. The steel pipe is also called electric welded steel pipe during the welding process of low-pressure working fluid for transportation, commonly known as white pipe. It is a hot-dip welded steel pipe used for general low-cost pressure calculation fluids such as water, gas, air oil, heating, steam, and warm water in enterprises or other main purposes. The wall thickness of the steel pipe is divided into a common steel pipe and a thickened steel pipe; the form of the pipe end can be divided into an internal non-threaded steel pipe and a threaded steel pipe. The specification of the steel pipe is indicated by the nominal maximum diameter, which is an approximation of the inner diameter. It is customary for us to use inch hints, such as 11/2 and so on.

3. Ordinary carbon steel wire casing is a steel pipe used to protect wires in electrical installation projects such as industrial and civilian buildings, installation machinery and equipment.

4. The straight seam electric welded steel pipe is a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. It is generally divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on.

5. The pressure fluid conveying sawtooth pipe is a sawtooth pipe formed by hot-rolled steel coil and normal temperature spiral forming and double-sided submerged arc welding. The steel pipe has strong bearing capacity, good welding performance, strict and scientific testing, and safe and reliable use. The steel pipe has a large diameter and high transmission efficiency, which can save investment in laying pipelines. Mainly used for pipelines for transporting oil and natural gas.

1. Classification by production method

Hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, and top-welded pipe are respectively welded according to the process, electric resistance welded pipe, gas welded pipe, furnace welded pipe. According to the welding seam, the straight seam welded pipe and spiral welded pipe

2. According to the shape of the section

Simple steel round pipes, stainless steel strips, oval steel pipes, triangular steel pipes, hexagonal steel pipes, diamond steel pipes, octagonal steel pipes, semi-circular steel pipes, other complex steel pipes, non-equilateral hexagonal steel pipes, five-petal plum-shaped steel pipes, double convex Steel pipe, melon-shaped steel pipe, tapered steel pipe, corrugated steel pipe, box-shaped steel pipe, etc.

3. Wall thickness classification of thin-walled and thick-walled steel pipes

4. According to the classification system, steel pipes for pipelines, steel pipes for thermal equipment, steel pipes for mechanical and electronic industries, steel pipes for petroleum, geological drilling, steel pipes for containers, steel pipes for chemical development industries, especially important uses and steel pipes.
