FAQ
What certifications do your drilling equipment hoses hold?
Our products are certified to API Spec Q1 quality management system standards and API Spec 7K for drilling and well servicing equipment. We also maintain ISO 9001:2015 certification and comply with DNV, ABS, and other international marine standards for offshore applications.
How do you ensure product quality consistency?
Quality control begins with raw material inspection using our advanced rubber analysis lab. Every hose undergoes 100% pressure testing at 1.5x working pressure, with random samples subjected to burst testing at 3x working pressure. Our computer-controlled testing systems generate detailed reports for each production batch.
What is the typical lead time for custom hose assemblies?
Standard orders ship within 10-15 working days, while custom assemblies require 3-4 weeks depending on complexity. We maintain strategic inventory levels of common components to expedite custom orders, and our production scheduling system provides real-time updates on order progress.
How should drilling hoses be stored when not in use?
Hoses should be stored in a cool, dry environment away from direct sunlight and chemicals. They should be coiled loosely (never folded) and supported on both ends to prevent deformation. Maximum storage temperature should not exceed 50°C, and hoses should be rotated periodically to prevent permanent set.
What maintenance procedures extend hose lifespan?
Daily inspections should check for external damage, kinks, or abrasions. Monthly hydrostatic testing is recommended for critical applications. After each use, hoses should be flushed with clean water and dried thoroughly. Store with ends capped to prevent contamination. Our maintenance guide provides detailed procedures for different operating environments.
