Stainless steel seamless steel pipe and stainless steel welded steel pipe (welded steel pipe) the basic two categories
Steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, it is convenient to carry out various processing
Galvanized coil, the thin steel plate is dipped into the melted zinc tank, so that its surface adheres to a layer of zinc thin steel plate.
Seamless stainless steel pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid tube blank perforated into a tube, and then made of hot rolled, cold rolled or cold drawn. The specifications of the seamless steel pipe are expressed by the outer diameter * the wall thickness of millimeters.
The forming coils are mainly hot rolled coils and cold rolled coils. Hot rolled coils are processed before the billet is recrystallized. Cold-rolled coil is the follow-up process of hot-rolled coil. The general weight of the steel coil is about 15-30T. China's hot rolling production capacity continues to expand, there are dozens of hot rolling production lines, and some projects are about to be built or invested
The passivation treatment of galvanized layer can reduce the folding rust (white rust) under the condition of moisture temperature storage and transportation. However, the anti-corrosion properties of this chemical treatment are limited, and hinder the adhesion of most coatings. This treatment is generally not used in zinc-iron alloy coating, in addition to finishing the surface, as a routine, the manufacturer of other types of galvanized layer are passivated treatment.

Stainless steel pipes are generally used to measure the hardness of Brinell, Rockwell, Vickers three hardness indicators.
High precision steel pipe material
Stainless steel belt is also called coil, coil material, coil plate, plate roll, the hardness of the belt is also a lot. Stainless steel features: 1. Complete product specifications, diverse materials; 2. High dimensional accuracy, up to ±0.1mm; 3. Good surface quality, good brightness; 4. Strong corrosion resistance, high tensile strength and fatigue strength; 5. Stable chemical composition, pure steel, low inclusion content; 6. Good packaging, favorable price; 7. It can be done without calibration.
For annealed stainless steel pipes with inner diameter above 6.0mm and wall thickness below 13mm, W-B75 Wechsler hardness tester can be used, which is very fast and simple to test and suitable for rapid and non-destructive qualification inspection of stainless steel pipes. For stainless steel pipes with inner diameter greater than 30mm and wall thickness greater than 1.2mm, Rockwell hardness tester is used to test HRB and HRC hardness.
Precision steel pipe high size precision, high surface finish inside and outside the pipe, no oxide film inside and outside the surface of the steel pipe after heat treatment, steel pipe expansion, flattening without cracks, cold bending without deformation, and can withstand high pressure, can make a variety of complex deformation and mechanical deep processing.

Seamless steel pipe is perforated by the whole round steel, and the steel pipe with no weld on the surface is called seamless steel pipe. According to the production method, the seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, pipe jacking and so on
The materials are ordinary and high-quality carbon structural steel (Q215-A ~ Q275-A and 10 ~ 50 steel), low alloy steel (09MnV, 16Mn, etc.), alloy steel, stainless acid-resistant steel and so on.

According to the use is divided into general purpose (for water, gas pipelines and structural parts, mechanical parts) and special (for boilers, geological exploration, bearings, acid resistance, etc.) two categories.

The seamless steel pipe has a hollow cross-section and is widely used as a pipeline for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is light in weight while bending and torsional strength is the same, and it is an economic cross-section steel.
Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction and other steel pipe manufacturing ring parts, can improve material utilization, simplify the manufacturing process, save materials and processing hours, has been widely used to manufacture steel pipe.
Jinan Steel thick plate galvanized plate seamless steel pipe
The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, the wall thickness is 2.5-200mm, the outer diameter of the cold-rolled seamless steel pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, the wall thickness is less than 0.25mm, and the size accuracy is higher than that of the hot-rolled seamless pipe.
