FAQ
What makes your drilling hoses different from other manufacturers?
Our GNG series hoses feature proprietary fire-resistant compounds developed through 8 years of R&D. The unique material formulation provides 30 minutes of fire resistance at 700°C while maintaining flexibility at -40°C, outperforming standard API requirements.
How do you ensure consistent quality across large production batches?
We implement statistical process control (SPC) throughout manufacturing. Key parameters like braiding tension, curing temperature, and crimping force are continuously monitored and adjusted using our centralized production management system.
What is your minimum order quantity for custom hoses?
For standard sizes, we accept orders starting from 50 meters. For custom specifications (special lengths, fittings, or pressure ratings), the MOQ is 200 meters to ensure cost-effective production.
How long does API certification remain valid?
Our API Spec 7K and Q1 certifications require annual surveillance audits and full recertification every three years. This ensures our manufacturing processes always comply with the latest API standards.
Do you provide after-sales support for installed hoses?
Yes, we offer comprehensive after-sales services including:
- On-site inspection and failure analysis
- Training for proper hose installation and maintenance
- Spare parts supply within 72 hours
- Product upgrade recommendations based on operational data
