Carbon Steel Square Tube, Features And Uses

1.carbon steel square tube The product description
Carbon steel square tube is a kind of hollow square cross section light thin wall steel tube, also known as steel refrigeration bend section. It is made of Q235 hot rolled or cold rolled strip steel or coil plate as base material by cold bending forming and then by high frequency welding made of square section shape and size of steel. In addition to the thickening of the wall, the corner size and edge flatness of hot rolled extra-thick wall square tube reach or even exceed the level of resistance welding cold forming square tube.

2.carbon steel square tube use
Carbon steel square tube is used in construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, car chassis, airport, boiler construction, highway railings, housing construction, etc.

Carbon Steel Square Tube, Classification

1. Classification of square tube production process
Square tube according to the production process: hot rolled seamless square tube, cold drawn seamless square tube, squeeze seamless square tube, welded square tube.

The welded square pipe is divided into:

(a) Divided by process — arc welding square pipe, resistance welding square pipe (high frequency, low frequency), gas welding square pipe, furnace welding square pipe

(b) Divided by weld — straight seam welded square pipe, spiral welded square pipe

2. Material classification of square tube
Square tube according to the material: plain carbon steel square tube, low alloy square tube. General carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel; Low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.

3. Standard classification of square tube production
Square tube according to production standards: gb square tube, Japanese standard square tube, British system square tube, American standard square tube, European standard square tube, non-standard square tube.

4. Shape classification of square tube section
Square pipes are classified according to section shape:

(1) simple section square pipe — square pipe, rectangular square pipe

(2) complex section square tube – flower shaped square tube, open square tube, corrugated square tube, shaped square tube

5. Classification of square tube surface treatment
Square tube according to the surface treatment: hot dip galvanized square tube, electric galvanized square tube, oil coated square tube, pickling square tube

6. Classification of square pipe use
Square tubes are classified according to their uses — square tubes for decoration, square tubes for machine tools, square tubes for mechanical industry, square tubes for chemical industry, square tubes for steel structures, square tubes for shipbuilding, square tubes for automobiles, square tubes for steel beams and columns, square tubes for special purposes

7. Classification of square tube wall thickness
Square tubes are classified according to wall thickness – ultra thick wall square tubes, thick wall square tubes and thin wall square tubes

Square Tube Performance

The plastic
Plasticity refers to the ability of a metal material to produce plastic deformation (permanent deformation) without damage under load.

Hardness
Hardness is a gauge of how hard or soft a metal material is. At present, the most commonly used method to determine hardness in production is the indenter hardness method, which is to use a certain geometric shape of the indenter head under a certain load into the surface of the tested metal materials, according to the degree of the indenter to determine its hardness value.

Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods.

Fatigue
The strength, plasticity, and hardness discussed above are indicators of the mechanical properties of metals under static loading. In fact, many machine parts are operated under cyclic loads, and fatigue can occur under these conditions.

Impact toughness
The load acting on the parts at a high speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.

The Intensity Of Square Tube

Strength is the ability of a metal material to resist failure (excessive plastic deformation or fracture) under static loading. Due to the mode of loading in the form of stretching, compression, bending, shearing, so the strength is also divided into tensile strength, compressive strength, bending strength, shear strength and so on. There is often a certain connection between various strengths, and tensile strength is generally used as the most basic strength pointer.

Square Tube Specifications And Implementation Standards

1. It can comply with gb6728-2002 cold-formed hollow section steel standard for structure.

2. Can comply with JISG3466-88 Japanese standard of general construction square rectangular tube fit range.

Square Management Market Circulation Calculation Formula

Square tube weight calculation formula: side length *4* wall thickness *0.00785

Formula for calculating the weight of rectangular tube per meter :( side length + side length) *2* wall thickness *0.00785
