using hot rolled steel pipe billet to make heating and piercing, elongating, sizing and stranghtening, cooling, finally hollow bars finished, this is the type most commonly used. Because it is hot rolled, so cost is lowest, but it is suit for large quantity, for small quantity, have to make cold drawn or round bar piercing. size:outer diameter 32mm- 499mm , wall thickness 4mm- 80mm

Differences between Hot Rolled and Cold Rolled Seamless Aug 19, 2020 · Cold-rolled seamless tubes are rolled below the recrystallization temperature, while hot-rolled seamless tubes are rolled above the recrystallization temperature. Advantages:It can destroy the casting structure of the steel ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved.
Hot rolled steel tubes are delivered in hot rolled or heat treated state; cold rolled steel tubes are delivered in heat treated state. Allowable deviation of standardized outer diameter:D1 ± 1.5%, minimum ± 0.75 mm D2 ± 1.0%. ± 0.50 mm D3 ± 0.75%, minimum ± 0.30 mm D4 ± 0.50%. ± 0.10 mm Steel pipe weight calculation formula
Hot-rolled and cold-rolled seamless steel pipe features Apr 02, 2021 · Hot rolled seamless steel tubes are divided into general steel pipes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. The main differences between hot rolled and cold rolled seamless steel tubes are:1.
How to distinguish hot rolling and cold rolling seamless tube?Cold rolled seamless pipe in addition to include the general steel, low and medium pressure boiler tube, high-pressure boiler tubes, alloy steel pipe, stainless steel pipe and oil cracking tube, also includes carbon thin wall steel pipe, alloy thin wall steel tube, thin-walled stainless steel pipe and special-shaped steel tube. The diameter of cold rolled seamless steel pipe is 6mm, wall thickness is 0.25mm, while the diameter of thin-walled tube
To be exact, the NOM B-203 Grade 1026 mechanical pipes contains about 0.4% silicon and 1.2% manganese. There are several specifications covered by carbon steel grade SAE 1026 Tubing including ASTM A29, ASTM A510, ASTM A512 as well as ASTM A513. The ASTM A29 Grade 1026 Boiler Pipes envelop both cold-finished and hot-rolled components.
Steel Tubing Hot Rolled Steel Tubing Cold Rolled Steel Cold Rolled Steel Tubing This steel tubing begins as hot rolled steel but is processed even further to create a more finished surface and provide additional strength. This process is more suited for applications that have strict tolerance, straightness, and surface condition requirements because cold rolling is a more precise finishing method.
