Product Categories & Features

1. Composite Oil Hose: Designed for suction and discharge of petrol, diesel, fuel oils, and hydrocarbons with up to 100% aromatic content (Types GGP, GSP, SSP)[cite: 31].

2. Composite Chemical Hose: Antistatic special hose for transferring aggressive, volatile chemicals and corrosive liquids in railcar/road tankers and storage tanks (Types SGP, PGP, SSP, SGT, SST, TST)[cite: 32].

3. Heavy Duty Loading Hose: Professional marine loading hose engineered for bulk chemical and petroleum transfers at dockside, ship-to-shore, and ship-to-ship facilities[cite: 32].

4. Low Temperature / Cryogenic Hose: Stainless steel wire reinforced composite hoses designed for cryogenic liquid gases including propane, butane, refrigerant gases, and ammonia[cite: 34].

Construction & Material Options

Inner & Outer Wires: Galvanized carbon steel (G), Stainless steel 304/316 (S), PP coated steel (P), or Teflon coated steel[cite: 31, 32].
Inner Layer Films: Polypropylene (PP), PTFE/Teflon, PE, NYLON, or FEP multi-layer films providing optimal chemical resistance and zero permeation[cite: 31, 32].
Safety Factor: 4:1 safety factor across oil, chemical, and loading hose series[cite: 31, 32].

Installation & Maintenance Guidelines

Proper Bending: Always respect the minimum bend radius; never over-flex or twist the hose assembly during installation[cite: 34].
Electrical Continuity: Regularly test end-to-end electrical continuity to safely dissipate static electricity during flammable liquid transfers[cite: 35].
Cleaning & Pressure Testing: Flush with clean water and perform hydrostatic pressure testing (1.5x working pressure) annually to ensure leak-free operation[cite: 35].
