9. Spiral steel pipe pile principles and requirement

1). The spiral pipe stacking principle requires that at palletizing firm to ensure the safety of the premise, to do according to species, size palletizing, different varieties of materials to be separately palletizing to prevent muddy and mutual erosion;

2). Do not store the erosion of steel have items in place around the spiral steel pipe pile;

3). Spiral Pipe pile bottom should elevate, firm, smooth, damp or prevent material deformation;

4) The same material has separately by stacking storage;

5). The open dumps spiral pipe steel, the following must have wood or stone pad, pile surface is slightly inclined to facilitate drainage, and pay attention to the material placed flat to prevent the causing bending deformation;

6). spiral steel stacking height, artificial homework does not exceed 1.2m, mechanical homework does not exceed 1.5m, pile width not exceeding 2.5m;

7) It should leave some passages between the stacks and stacks 7. Check road is generally 0.5m, of access depending on the size of the material and transport machinery, generally of 1.5 ~ 2.0m;

8). open dumps angles and channels should stoop to put that mouth down, I-beam shall stand up, I can not groove surface of steel up to avoid stagnant water rust;

9). pile bottom booster, if the warehouse is sunny concrete floor, can elevate 0.1m; if the mud, to be boosted 0.2 ~ 0.5m. If it is open space, concrete floor booster 0.3 ~ 0.5m, mud face booster 0.5 ~ 0.7m.

10. 2PE/ 3PE anti-corrosion and single-layer PE anticorrosive

4) 3PE anticorrosive and external single PE anticorrosive performance comparison

11. Coal tar epoxy

1) Composition:
The product is formulated with an epoxy resin, coal tar pitch, anti-rust pigments, additives, modified amine from. Products with rapid drying, good adhesion, flexibility, and easy two-component packaging and construction. With acid, alkali, salt, water, oil etc.

①The paint combination of high mechanical strength epoxy resin adhesive force, erosion and chemical resistance characteristics of asphalt water-resistant, anti-microbial, anti-plant roots, is a high performance anti-corrosion insulation coating, the products are Good chemical resistance, water resistance.

4) The process has been the duty epoxy powder coating using electrostatic spraying. Since epoxy powder Jin Su troubled by adhesion, epoxy powder dip has not been able to promote. Current come with three coconut epoxy powder dip developed special phosphate solution, for the first time to overcome the adherence problem epoxy powder dip process, began to dip epoxy powder of this emerging technology.
