Spiral steel pipe (steel‑jacketed, steel‑insulated pipe) manufacturers shall strengthen moisture testing of raw materials prior to storage, strictly adhere to the requirements of the “Quality Inspection Procedures for Raw Materials Prior to Storage,” and conduct individual inspections of all materials. Moisture content must be verified; any products that fail inspection shall not be stored and must be re‑packaged with waterproof materials and covered with waterproof tarpaulins, while transport management should be further enhanced.
Summer is a rainy season, so what are the moisture‑proofing measures for spiral steel pipes during the summer (rainy season)? Our editor is here to introduce them.
Spiral steel pipe (Steel‑jacketed, steel‑insulated pipes) Manufacturers should strengthen moisture testing of raw materials prior to storage, strictly adhere to the requirements of the “Quality Inspection Procedures for Raw Materials Before Storage,” and conduct individual inspections of all materials. Moisture content must be verified; any products failing inspection are to be withheld from storage and subjected to waterproof packaging, covered with waterproof tarpaulins, and other appropriate measures. Transportation management must also be enhanced. Moisture‑proofing and waterproof protection of incoming raw materials should be reinforced by repairing warehouse roofs, classifying and storing materials according to their properties, and ensuring adequate spacing to promote ventilation and dryness. On overcast or rainy days, materials should be covered with waterproof tarpaulins. Moisture testing of outgoing materials has been intensified, requiring batch‑wise moisture checks upon dispatch; the supply of non‑conforming products is to be firmly halted. Furthermore, vehicles leaving the warehouse must always be fitted with rain‑proof covers, and daily inspections for damage must be conducted. Moisture testing of bulk materials supplied directly—such as lime and lightly calcined materials—should be strengthened, with close attention paid to rapidly changing weather conditions. On overcast or rainy days, dedicated personnel should be assigned to monitor and supervise these materials, preventing wet materials from entering the furnace.
Spiral steel pipes are widely used in high-rise building water supply and drainage, fire sprinkler systems, HVAC systems, coal mine gas venting, corrosion‑resistant applications for both internal and external cable installations, natural gas pipelines, chilled and hot water circulation systems, as well as in systems requiring heat resistance and corrosion protection; they also serve seawater circulation systems, industrial systems, circulating water systems, deionized pure water systems, wear‑resistant and corrosion‑protective systems, anti‑scale, antibacterial, and corrosion‑preventive systems, internal and external anti‑corrosion systems, cable sheathing, fire‑sprinkler systems, insulating and anti‑corrosion systems, and heavy‑duty chemical anti‑corrosion systems, among others.
