The spot price of the outer diameter (outer edge diameter) of 168mm seamless steel pipe is 4450 yuan / ton, and the price is inclusive of tax. GB9948 seamless steel pipe seamless steel pipe is expressed as outer diameter, wall thickness, thick wall seamless steel pipe is mainly used for machining, coal mine, hydraulic steel, and other purposes. Large quantities can be discounted, quantities greater than 40 tons are 4,400 yuan / ton, quantities greater than 100 tons are priced at 4,350 yuan / ton. The acceptance price is increased by 150-180 yuan / ton. Note: This price is excluding shipping price, and the shipping cost shall be borne by the buyer.
Seamless steel tubes are used extensively. B3087 seamless steel tube is divided into structural seamless steel tube according to use; seamless steel tube for transportation; seamless steel tube for boiler; high-pressure seamless steel tube for boiler. The seamless steel tube for general use consists of ordinary carbon (C) structure (Structure ) Steel, low-alloy structural steel or alloy structural steel is rolled with the largest output. It is mainly used as a conduit or structural part for conveying fluids. 2. It is divided into three categories according to different uses:
A. Supply according to chemical composition and mechanical performance (xìng néng);
B. Supply according to mechanical properties;
C. Supply according to water pressure (specifically: pressure) test. For steel pipes supplied according to categories A and b, if they are used to withstand liquid pressure (pressure), water pressure (specifically: pressure) test is also required. GB9948 seamless steel pipe is divided into high pressure seamless steel pipe for fertilizer equipment according to the purpose; seamless steel pipe for geological brick exploration; seamless steel pipe for petroleum brick exploration; seamless steel pipe for petroleum cracking; seamless steel pipe for ships; cold drawn cold rolled precision Seamless steel pipes; various alloy pipes. 3. Special-purpose seamless pipes include seamless pipes for boilers, chemical and electric power, seamless steel pipes for geology, and seamless pipes for petroleum. Seamless steel pipes have a hollow cross-section and are widely used as pipelines for conveying fluids, such as pipelines for transporting petroleum, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipe is an economical section steel with lighter weight when the bending strength and torsional strength are the same. Widely used in the manufacture of structure parts and machinery parts, such as oil drill pipe, auto drive shaft (composed of drive shaft: shaft tube, telescopic sleeve and universal joint), bicycle frame and architecture Steel pipes used in construction, such as steel scaffolding, are used to manufacture ring parts, which can improve the availability of materials, simplify the manufacturing process, and save material and processing hours. Steel pipes have been widely used for manufacturing.
