Bridge Support Spiral Pipe, Jieyang Piling Spiral Pipe Manufacturer

Helicoidal steel pipe storage principles require:

1. The principle for stacking spiral steel pipes requires that it be done securely and safely, with sorting by type and specification. Different types of materials should be stacked separately to prevent mixing and mutual corrosion.

2. Prohibit the storage of items that erode steel around the piles of spiral steel pipes.

3. Spiral steel pipe stacks should be elevated, sturdy, and flat to prevent materials from getting damp or deformed.

4. Materials of the same type are stacked separately according to the order of entry.

5. Spiral steel pipes should be stacked outdoors with wooden pads or flagstones underneath. The pile should be slightly inclined for drainage purposes. Pay attention to placing the materials flat to prevent bending and deformation.

6. The stacking height of spiral steel pipes should not exceed 1.2m for manual labor and 1.5m for mechanical handling, with a width not exceeding 2.5m.

7. Adequate aisles between stacks should be provided; the standard aisle width for inspection is typically 0.5m, while entry and exit aisles are determined by the size of the materials and the transport equipment, usually ranging from 1.5 to 2.0m.

8. Angle and channel steel should be placed flat, with the opening facing down, while I-beams should be stood upright. The I-slot surface of the steel should not face upwards to prevent water accumulation and rust.

9. Pile foundation elevation: If the warehouse is a sunny concrete floor, an elevation of 0.1m is sufficient; for earthen ground, it should be elevated 0.2 to 0.5m. For outdoor sites, concrete floor elevation should be 0.3 to 0.5m, and sandy soil 0.5 to 0.7m.

Spiral pipes are primarily used in water supply projects, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction, ranking among the top 20 key products developed in our country. They are used for liquid transportation, including water supply, drainage, sewage treatment, sludge transportation, and seawater conveyance. For gas transportation, they are used for coal gas and steam. As structural materials, they serve as pile pipes, bridge construction, wharf, road, and building structural pipes, as well as offshore pile pipes.

GB Standard Spiral Steel Pipe Material Application:

Standard Spiral Steel Pipe, abbreviated as 9711.1 Spiral Steel Pipe, 9711.2 Spiral Steel Pipe, material types include 16Mn Spiral Steel Pipe, Q345B Spiral Steel Pipe, L245 Spiral Steel Pipe, L360 Spiral Steel Pipe, X40-X80 Spiral Steel Pipe. Main applications: sewage treatment spiral steel pipe, water purification spiral steel pipe, waterworks spiral steel pipe, power plant and chemical industry spiral steel pipe, nuclear power spiral steel pipe, spiral steel pipe for conveying flammable fluids, spiral steel pipe for conveying non-flammable fluids, national standard spiral steel pipe, and Petroleum Department standard SY/T5037 Spiral Steel Pipe. This product is made from hot-rolled steel strips, formed by normal temperature spiral rolling, and welded using automatic submerged arc welding technology. The product conforms to API SPEC 5L, EN10217, GB/T9711.1, and GB/T9711.2 standards. Mainly used for conveying flammable and non-flammable fluids in the oil and natural gas industries, as well as in steel structures.

Helical pipes themselves do not heat up, but the experimental samples will significantly overheat. At temperatures exceeding those of the arc melting machine, the radio frequency inductor provides greater control, allowing scientists to adjust the specific composition of the alloy. Helical steel pipes have strong pressure-bearing capacity, good plasticity, and are easy to weld and shape. Generally, low-pressure fluid transmission helical seam submerged arc welding steel pipes (SY5037-83) are used for water, coal gas, air, and steam, etc., and are manufactured using double-sided automatic submerged arc welding or single-sided welding methods.
