FAQ
What makes your drilling hoses different from generic products?
Our hoses undergo 300% more impulse testing cycles than industry requirements. Each batch is tested to 1.5x working pressure before shipment, ensuring zero failure rates in field operations.
How do you ensure compliance with international standards?
In addition to API certifications, we maintain ISO 9001, ISO 14001, and OHSAS 18001 management systems. Our QC team includes API-authorized auditors who conduct monthly internal reviews.
Can you provide custom hose assemblies?
Yes, we offer complete customization including:
- Non-standard lengths up to 100 meters
- Special end fittings for unique equipment
- Color-coding for easy identification
- RFID tracking tags for inventory management
What is your typical lead time for bulk orders?
For standard products, we maintain 30 days’ inventory in our 5,000㎡ warehouse. Custom orders require 45-60 days production time depending on specifications.
How do you handle quality complaints?
We follow a 24-hour response protocol for any field failures. Our engineering team will analyze root causes and provide replacement products within 72 hours for critical components.
