  There are many seamless pipes on the construction sites around us, and we don’t know what some seamless pipes are. Today we will talk about Super Austenitic Stainless Steel Seamless Pipe and Tube . Austenitic stainless steel refers to stainless steel with an austenitic structure at room temperature. When the steel contains cr about 18%, ni 8%-10%, and c about 0.1%, it has a stable austenite structure. The austenitic chromium-nickel stainless steel includes the famous 18cr-8ni steel and the high-cr-ni series steel developed by increasing the content of cr and ni and adding mo, cu, si, nb, ti, and other elements on this basis. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low, and it is impossible to strengthen it through phase transformation. It can only be strengthened by cold working, such as adding s, ca, se, te, and other elements, it has good Machinability. The same goes for Austenitic Stainless Steel Seamless Pipe . yintuosteel.com

  The definition of Austenitic Stainless Steel Seamless Tube is the smelting and manufacturing of stainless steel in which the ferrite phase and the austenite phase in its solid-quenched structure are each half. The austenitic stainless steel seamless tube material has excellent mechanical properties, corrosion resistance, and good weldability, and has a wide range of uses in the oil and gas industry, marine engineering, chemical industry, and other industries. The length of the oil and gas pipelines laid by duplex stainless steel in the oil and natural gas industry has exceeded 850Km, most of which are austenitic stainless steel seamless tubes; the West-East Gas Pipeline is highly corrosive due to the corrosive nature of the natural gas medium, so the high-pressure pipelines are all austenitic stainless steel seamless tubes. tube material. The austenitic stainless steel seamless tubes combine the most beneficial properties of ferrite and austenite and have good resistance to chloride-ion stress corrosion cracking. The Ferritic Stainless Steel Seamless Pipe and Tube only has the performance of ferrite. yintuosteel.com

  We can see Alloy Steel Seamless Pipe in many places, including various factories. Today, let’s talk about what Alloy Steel Seamless Pipe is. Alloy Steel Seamless Pipe has a long strip of steel with a hollow section and no joints on the periphery. Steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, Alloy Steel Seamless Pipe has a lighter weight when the bending and torsion strength is the same. It is a kind of economical cross-section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as petroleum transportation, stair railing, Bicycle racks, and steel scaffolding used in construction. The use of alloy seamless steel pipes to manufacture annular parts can increase the utilization rate of materials, simplify the manufacturing process, and save materials and processing man-hours. For example, rolling bearing rings, jack sleeves, etc., have been widely used for manufacturing steel pipes. The performance effect of Nickel Alloy Seamless Pipe and Tube is also very extensive. yintuosteel.com

  There are many seamless pipes around us, and Stainless Steel Seamless Pipe is one of them. Today we will talk about the specifications and appearance quality of Stainless Steel Seamless Pipe. According to the provisions of GB14975-2002 "Stainless Steel Seamless Steel Tubes", steel pipes usually have a length (indefinite length) of hot-rolled steel pipes of 1.5-10m, and hot-extruded steel pipes are equal to and greater than 1m. For cold-drawn (rolled) steel pipes with a wall thickness of 0.5-1.0mm, 1.0-7m; for those with a wall thickness greater than 1.0mm, 1.5-8m. There are 45 kinds of hot-rolled (hot-extruded) steel pipes with a diameter of 54-480mm; a total of 36 kids with a wall thickness of 4.5-45mm. There are 65 kinds of cold-drawn (rolled) steel pipes with a diameter of 6～200mm, and 39 kids with a wall thickness of 0.5～21mm. The inner and outer surfaces of the steel pipe shall not have cracks, folds, cracks, cracks, rolling, delamination and scarring defects. These defects shall be completely removed (except for pipes for mechanical processing). After removal, the wall thickness and outer diameter shall not exceed Negative deviation. Other minor surface defects that do not exceed the allowable negative deviation may not be removed. Straights allow depth. Hot-rolled and hot-extruded steel pipes with a diameter less than or equal to 140mm are not greater than 5% of the nominal wall thickness, and the maximum depth is not greater than 0.5mm; cold drawn (rolled) steel pipes are not greater than 4% of the nominal wall thickness, and the maximum depth is not greater than 0.3 mm. Both ends of the steel pipe should be cut at right angles and burrs should be removed. yintuosteel.com
