Thick-walled steel pipe maintenance

The key quality of thick-walled steel pipe plant to the number of wall thickness uniformity, thickness of the thick steel pipe unchecked will directly affect the quality and use of steel, thick-walled steel pipe, large diameter seamless steel pipe is generally used in the kinds of machining, thick-walled parts processing, even thick-walled steel pipe wall will directly affect the quality of post-processing components, thick-walled steel pipe wall is not controlled, the overall quality is not strictly a steel pipe. Select the appropriate venues and thick-walled steel warehouse storage site or warehouse, should be selected in the clean, smooth drainage area, away from harmful gases or dust factories and mines. Presence on the ground to clear all the weeds and debris, keeping thick-walled steel pipe clean. In a warehouse not with acid, alkali, salt, cement and other thick tube aggressive materials stacked together. Different varieties of thick-walled steel should be stacked separately, to prevent confusion and to prevent contact corrosion. Heavy sections, rails, shame steel, large diameter thick wall steel pipe, forgings, etc., may open dumps.

Sized steel, wire rod, rebar, in diameter thick wall steel pipe, steel wire and wire rope, etc., can be expected in a well-ventilated storage shed, but it must be on the thatch underlay. Some small thick-walled steel pipe, sheet, strip, silicon, or thin-walled small-caliber thick-walled steel pipe, a variety of cold-rolled, cold-drawn thick-walled steel pipe and high prices, corrosive metal products, can be stored for storage. Treasury should be based on selected geographical conditions, the general ordinary enclosed warehouse, that is the roof with walls, doors and windows tight, with the Treasury ventilation device. Treasury requirements sunny attention to ventilation, rain close attention to moisture, and keep proper storage environment. Reasonable stacking, advanced first put principle requires stacking under palletizing firm to ensure safe conditions, so that according to species, palletizing specifications, different varieties of materials to palletizing respectively, to prevent confusion and mutual corrosion prohibited store near the pile of thick-walled steel bits have a corrosive effect items, principles of open dumps steel, the following must be wood or stone pad, pile surface is slightly inclined to facilitate drainage, and pay attention to the material placed flat against bending caused deformation stack height does not exceed the manual work of 1.2m, no more than 1.5m mechanical work, stack no larger than 2.5m. should leave some passages between the stacks and stacks, check road usually O.5m, of access depending on the size and material transport machinery, generally is 1.5 ~ 2.Om pile bottom booster, if the warehouse Chaoyang cement floor, to elevate O.1m; if the mud, shall elevate O. 2 ~ 0.5m. If it is open space, concrete floor booster O.3 ~ O.5m, mud surface booster 0.5 ~ O.7m. Open dumps angles and channels should stoop to put that mouth down, beam shall stand up, I can not be thick-walled steel tank surface facing up, in order to avoid water rust.
