Thick-walled piling pipe custody and maintenance

Thick-walled  piling pipe custody and maintenance of the quality of key thick steel wall thickness uniformity to the number of thick-walled steel pipe wall thickness is not controlled will directly affect the quality and usefulness of steel pipe, thick wall steel pipe, large diameter seamless steel pipe generally used in a variety of machining, thick-walled parts processing, uniform wall thick-walled steel pipe will directly affect the quality of post-processed parts, thick-walled steel pipe wall is not controlled, the overall quality of steel is not strictly . Appropriate choice of venue and warehouse storage space or warehouse thick steel, should be selected in clean, smooth drainage area, away from harmful gases or dust factories. Presence on the ground to clear the weeds and all debris, keep the thick-walled steel pipe clean. Not in a warehouse with acid, alkali, salt, cement and other thick-walled steel pipe with corrosive materials stacked together. Different varieties of thick-walled steel pipe should be stacked separately, to prevent confusion, to prevent contact corrosion. Large steel, rails, shame steel, large diameter seamless steel pipe, forgings, etc., may open air.

Small steel, wire rod, rebar, the diameter thick wall steel pipe, steel wire and wire rope, etc., can be expected in a well-ventilated storage shed, but must be on the thatch underlay. Some small thick-walled steel pipe, sheet, strip, silicon, or thin-walled small-diameter thick-walled steel pipe, a variety of cold-rolled, cold drawn thick wall steel pipe, and the price is high, corrosive metal products, can be stored in storage. Treasury should be selected according to geographical conditions, the general ordinary enclosed warehouse, ie roof with walls, doors and windows tightly with ventilation warehouse. Treasury requires attention to ventilation sunny, rainy close attention to moisture, and keep a suitable storage environment. Reasonable stacking, stacking principle advanced first put palletizing firm requirement is to ensure safe conditions, so that according to species, size stacking, different kinds of materials to be, respectively, palletizing, prevent confusion and mutual corrosion, prohibit pile position near the store have a corrosive effect on the thick-walled steel items principles open dumps steel, the following must be of stone or wood pad, stack face tilted slightly to facilitate drainage, and pay attention to materials placed flat against bending caused deformation stacking height, manual operation does not exceed 1.2m, mechanical operation does not exceed 1.5m, stack width not exceeding 2.5m. stacks and stacks should be left between a certain channel, check the road is generally O. 5m, entrances and exits, as the size of the material and transport machinery, generally 1.5 to 2. Om. Pile padded bottom, if the concrete floor warehouse of Chaoyang, booster O. 1m to; For mud, shall elevate O. 2 ~ 0.5m. For open space, concrete floor padded O · 3 ~ O · 5m, mud face booster 0.5 ~ O. 7m. Angles and channels open dumps should stoop to put that mouth down, I-beam should stand up, thick-walled steel pipe I can not groove face up, in order to avoid stagnant water rust.
