Engineering notes when using Longitudinal custody <br>1. Select an appropriate location and warehouse <br>(1) steel pipe storage locations or warehouses, factories and mines should be chosen in a clean clean, smooth drainage areas, away from harmful gases or dust occur. In place to eradicate all weeds and debris, adhere to pipe clean <br>(2) in a warehouse not with acid, alkali, salt, cement and other aggressive for steel materials stacked together. Different varieties of steel are to be grown, preventing thick cloud, preventing corrosion touch <br>(3) heavy sections, rails, shame steel, large-diameter steel pipes, forgings, etc. may be stacked open <br>(4) sized steel wire rod, rebar, in diameter pipe , wire rope and the like, can be well ventilated storage shed material, there is a need in the sheets underlying

Precautions for the safekeeping of straight welding tubes for engineering<br> 1. Choose the right place and warehouse<br> (1) The place or warehouse where the steel pipe is kept shall be chosen to stay away from the plant or mine where harmful gases or dust occur. In the place to eradicate weeds and all debris, adhere to the clean pipe<br> (2) In the warehouse shall not be with acid, alkali, salt, cement and other corrosive materials to the steel pipe stacked together. Different varieties of steel pipe should be stacked separately to prevent cloudy, to prevent touch corrosion<br> (3) Large-scale steel, rail, steel plate, large-calibre steel pipe, forgings, etc. can be stacked in the open air<br> (4) Small and medium-sized steel, plates, steel bars, medium-calibre steel pipes, wire and wire ropes, etc., can be stored in a well-ventilated shed, but it is necessary to put up and down the mat

Precautions for storage of Engineering straight welded pipe<br>1. Select appropriate place and warehouse<br>(1) the place or warehouse where the steel pipes are kept shall be clean and free of water and away from the factories or mines where harmful gases or dust occur. Weeds and all sundries shall be eradicated on the site, and steel pipes shall be kept clean<br>(2) it is not allowed to pile up with acid, alkali, salt, cement and other materials that are corrosive to steel pipes in the warehouse. Different types of steel pipes should be piled up separately to prevent turbidity and touch corrosion<br>(3) large section steel, steel rail, dishonored steel plate, large diameter steel pipe, forging, etc. can be stacked in the open air<br>(4) small and medium-sized section steel, wire rod, steel bar, medium diameter steel pipe, steel wire and steel wire rope can be stored in the well ventilated material shed, but it is necessary to cover and pad them<br>
