In construction steel, according to different construction purposes, the types of steel are also different, including square tubes. So for users who want to buy, what are the performance, process requirements and storage contents of square tube?
Square tube performance
Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without damage under load.
Hardness is a pointer to measure the hardness and softness of metal materials. At present, the common method for measuring hardness in production is the indentation hardness method. It uses an indenter with a certain geometry to press into the surface of the tested metal material under a certain load, and determines its hardness value according to the degree of indentation.
The load acting on the part at a great speed is called impact load, and the ability of metal to resist failure under impact load is called impact toughness.
Strength refers to the resistance of metal materials to failure (excessive plastic deformation or fracture) under static load.
Process requirements for square tube
1. The square pipe must be manufactured on the special import assembly line to ensure the manufacturing accuracy and tightness of the air pipe.
2. The blanking of square pipe fittings shall be completed automatically by using computer software on the imported special machine, and the automatic plasma cutting process shall be completed by the imported special plasma cutting machine for sheet metal.
3. The bite connection of square pipe shall adopt imported automatic bite device for bite process. wait.
Square tube preservation
The site or power station of rectangular tube goods shall choose the center that is being cleaned, pickled and drained smoothly, and be far away from factories and mines where harmless gas or dust occurs. Clean up weeds and all sundries on the site and maintain the steel pickling.
Heavy section steel, rail, steel plate, large-diameter bamboo pipe, standard parts, etc. can be stacked outdoors.
Medium and medium-sized section steel, wire rod, steel bone, medium diameter bamboo pipe, steel wire and steel wire rope can be deposited in the material shed with excellent ventilation, but they must be covered and padded.
Some medium-sized steel products, thin transcribed steel plates, steel strips, silicon wafers, small-diameter or thin-walled bamboo tubes, hot-rolled and cold drawn steel products of all ethnic groups, as well as high-priced and erodible non-metallic products, can be deposited and warehoused.
The warehouse shall be selected according to the astronomical environment, and the general open warehouse shall be adopted normally, that is, the warehouse with roof, enclosure, careful windows and doors and ventilation installation.
The warehouse is required to pay attention to ventilation in sunny days, open to moisture in rainy days, and maintain suitable storage conditions from time to time.
