(1) The site or warehouse for storing Q345B cold drawn square pipes should be located in a clean place with unobstructed drainage, far away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed on the field, and the Q345B cold drawn square tube should be kept clean;
(2) Do not stack with acid, alkali, Q345B square tube salt, Q345B square steel tube forming process knowledge, cement and other materials that are corrosive to Q345B cold drawn square tube in the warehouse. Different types of Q345B cold drawn square tubes should be stacked separately to prevent confusion and prevent contact corrosion;
(3) Large section steel, rails, steel plates, large diameter Q345B cold drawn square pipes, forgings, etc. can be stacked in the open;
(4) Small and medium-sized steel, wire rod, steel bar, Q345B square tube, Q345B cold-drawn square tube, steel wire and wire rope, etc., can be stored in a well-ventilated material shed, but must be top and bottom pads;
(5) Some small Q345B cold-drawn square tubes, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled Q345B cold-drawn square tubes, various cold-rolled, cold-drawn Q345B cold-drawn square tubes and high prices, Q345B square tubes Easily corrosive metal products can be stored in storage;
(6) The warehouse should be selected according to geographical conditions. The knowledge of the two forming processes of Q345B square steel pipes generally adopts ordinary closed warehouses, that is, warehouses with roofs and walls, tight doors and windows, and ventilation devices;
(7) The warehouse is required to be ventilated on sunny days, shut down to prevent moisture on rainy days, and always maintain a suitable storage environment
2. Reasonable stacking, put first
(1) The principle of stacking is to ensure that the stacking is stable and safe, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Material Co., Ltd. Varieties and specifications are palletized, and different types of materials must be palletized separately to prevent confusion and mutual corrosion;
(2) It is forbidden to store items that are corrosive to the Q345B cold drawn square tube near the stacking location;
(3) The bottom of the stack should be high, firm and flat to prevent the material from being damp or deformed;
(4) The same materials are stacked separately according to the order of storage, which is convenient for the implementation of the first-in-first-mover principle;
(5) For section steel stacked in the open air, there must be wooden mats or slabs underneath, the stacking surface is slightly inclined to facilitate drainage, and the materials should be placed straight to prevent bending and deformation;
(6) The stacking height is not more than 1.2m for manual operations, not more than 1.5m for mechanical operations, and the stack width is not more than 2.5m;
(7) There should be a certain passage between the stack and the stack, the inspection channel is generally 0.5m, and the access channel depends on the size of the material and the transportation machinery, generally 1.5～2.Om;
(8) The bottom of the stack is raised. If the warehouse is a sunny cement floor, the height of 0.1m is enough; if it is muddy, it must be raised by 0.2~0.5m. If it is an open field, the height of cement floor should be O·3～O·5m, and the height of sand and mud surface should be 0.5～O.7m. , The I groove surface of the Q345B cold drawn square tube should not face up to avoid rusting due to accumulation of water.
