Frequently Asked Questions (FAQ)
Q: How do 1400 Bar thermoplastic water jetting hoses maintain pressure stability during continuous operation?
A: Thermoplastic hoses utilize a rigid Nylon (PA) inner tube reinforced with four spiraled steel wire layers. This exact configuration minimizes internal volumetric expansion under dynamic 760 to 1400 Bar loads, ensuring consistent water jetting velocity and precise pressure transmission.
Q: What are the strict operating limits for high-pressure thermoplastic hoses in hull cleaning?
A: The documented thermal range is strictly -30°C to +80°C. The outer layer consists of extruded polyurethane, providing calibrated physical resistance against friction and environmental degradation commonly encountered during industrial vessel maintenance and continuous surface deposit blasting environments.
Q: What coupling assembly is specified for 4-spiral thermoplastic hoses exceeding 10,000 PSI?
A: For operational pressures ranging from 10,000 to 20,300 PSI (760-1400 Bar), engineered one-piece crimped fittings are mandatory. This integrated assembly eliminates point-of-failure vulnerabilities associated with multi-part couplings, maintaining structural sealing and mechanical integrity during extreme fluid applications.
