Stage ( & mdash; )It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter,The surface hardening treatment of qqb square tube is generally isothermal quenching, that is, heat treatment technology. After isothermal quenching, qqb square tube will obtain more and better properties, and make qqb square tube be applied in more fields.So flat,Hardness QB square hardness is a pointer to measure the hardness and softness of metal materials. At present, the hardness method is commonly used to measure the hardness in production. It uses the indenter with fixed geometry to measure the hardness value of the metal material surface tested under fixed load according to the degree of hardness.Cold drawn or cold rolled precision square tube (gb-) is a cold drawn or cold rolled precision square tube with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision square mechanical structure or hydraulic equipment can greatly save machining hours improve material rate and improve product quality.Square tubes for petroleum cracking (gb-) are furnace tubes, heat exchangers and pipeline square tubes suitable for petroleum refineries.

. fake and inferior square tubes are easy to fold. Folding is a variety of broken lines formed on the surface of square tubes, and this defect often runs through the longitudinal direction of the whole product. The reason for the folding is that the fake and shoddy manufacturers pursue the rate the reduction is too large, resulting in ears, folding occurs during the next rolling, the folded products will crack after bending, and the strength of the square tube will be greatly reduced.Large diameter welded square pipe for low pressure fluid transmission, Standard No.: gbt-. Representative material: grade qab. It is mainly used to transport low-pressure fluids such as water, sewage, gas, air and heating steam.It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter,RasglerGalvanized wire pipe and galvanized steel pipe, and R and R can be equal or different.retailer,Hot dip galvanized square tube is a kind of square tube which is welded after using steel plate or steel strip to curl and form, and on the basis of this square tube, the square tube is placed in the hot dip galvanized pool and formed through a series of chemical reactions; The production process of hot-dip galvanized square pipe is relatively simple, but the production efficiency is very high and there are many specifications and varieties, but this kind of square pipe needs little equipment and capital, which is more suitable for the production of small galvanized square pipe manufacturers.A. square tube structural steel: (a) high quality carbon structural steel; (b) Alloy structural steel; (c) Spring steel; (d) Easy cutting steel; (e) Bearing steel; (f) High quality structural steel for specific purposes.Precision inner diameter square tubes for hydraulic and pneumatic cylinders (gb-) are cold drawn or cold-rolled precision square tubes with precision inner diameter for hydraulic and pneumatic cylinders.

Stage ( & mdash; )Sales Department,Steel for construction and engineering according to the classification of use without phase transformation or partial phase transformation of square tube: A. ordinary carbon structural steel; b. Low alloy structural steel; c. Steel reinforcement.Solid bending, as the name suggests, is to compact the bending. During real bending, the inner and outer rollers and the inner and outer walls of the pipe blank are compacted in both directions.The reason why the surface of fake and shoddy materials is easy to crack is that its blank is adobe with many air holes. During the cooling process, the adobe has cracks due to the action of thermal stress, and there are cracks after rolling.Rasgler,Square tubes are classified by forming: forged steel; Cast steel; Hot rolled steel; Cold drawn steel.According to smelting classification and furnace type,Rasgler50 galvanized square pipe,Rasgler25mm galvanized water pipe, A. open hearth steel: (a) acid open hearth steel; (b) Alkaline open hearth steel.The load of impact toughness acting on the parts at a great speed is called impact load. It is specialized in products and renewable resources. Its business includes: square tube, square tube, seamless square tube, galvanized square tube and galvanized tube. The ability of metal under impact load is called impact toughness.
