A honed tube is a steel tube with a precision-processed inner surface, which has a high-precision inner diameter and good surface finish. Its main feature is that the inner surface is processed by a honing process, and is usually used in situations where a high-precision,

Q235 is a common carbon structural steel widely used in China. In the 88 version, Q235 is divided into four grades: A, B, C, and D according to quality grade. In addition to the composition (mainly the element content changes, with the increase of the

Steel wire is one of the four major types of steel: plate, tube, profile, and wire. It is a reprocessed product made from hot-rolled wire rods by cold drawing. The main processes of steel wire production include raw material selection, iron oxide removal, drying, coating

To answer this question, we need to understand the difference between low carbon steel and high carbon steel According to the chemical composition of steel, it can be divided into two categories: carbon steel and alloy steel. Carbon steel is further divided into: ① Low

Petroleum Oil cracking tubes are seamless tubes for furnace tubes, heat exchanger tubes and pipelines in oil refineries. In the process of oil refining, they are mainly used in cracking units. Cracking is a chemical process that breaks down long-chain hydrocarbon molecules into shorter molecules

 Flange is a pipe fitting part that connects shafts to each other and is used to connect pipe ends; there are also flanges used on equipment inlets and outlets, which are used to connect two devices, such as reducer flanges. Flange connection or flange joint

High-pressure boiler tubes are mainly used to manufacture superheaters, reheaters, water-cooled walls, economizers, etc. of supercritical or ultra-supercritical boilers. The steel tubes are required to have high endurance strength, high oxidation and corrosion resistance, and good structural stability. Main grades or steel grades: SA-179M, SA-192M,

Precision seamless steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish,

20# steel is a high-quality low-carbon steel, cold extruded carburized hardened steel with low strength, good toughness, plasticity and weldability, tensile strength of 355~500Mpa, and elongation of 24%. 20# is used for metal structures and components working at -40℃ to +450℃. Hot-rolled and forged long

A straight seam steel pipe is a steel pipe with a weld parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe, etc. The production process of straight
