Description
Drilling Rotary Hose - Abrasion Resistance, High Pressure Stability, Easy Installation
Product Overview

Rotary Drilling Hose is a flexible high-pressure hose developed for drilling fluid transfer systems where the connection must accommodate equipment movement, vibration, pressure fluctuation, and demanding environmental conditions. It is commonly incorporated into drilling rigs, offshore drilling units, well-servicing equipment, and associated fluid circulation systems where a flexible pressure connection is required between equipment components.

The hose consists of an inner rubber tube, multiple reinforcement layers, and an external protective cover. The inner tube provides the fluid-transfer passage and is selected according to the characteristics of the conveyed medium. Reinforcement layers provide the required mechanical and pressure resistance, while the outer cover protects the hose structure against abrasion, weather exposure, oil contamination, moisture, and general mechanical contact.

Case Study: Dynamic Hose Application on a Semi-Submersible Offshore Drilling Unit

An offshore drilling contractor operating a semi-submersible drilling unit required replacement high-pressure flexible hose assemblies for a drilling fluid circulation system. The drilling unit had an approximate displacement of 42,000 tonnes and was operating in a deep-water field where continuous drilling operations were being conducted.

Hongruntong Marine reviewed the customer's technical parameters and manufactured replacement assemblies with reinforced construction and a durable external cover suitable for the specified environment. The assemblies were pressure-tested and delivered with protective packaging to ensure safe transportation and offshore handling.

Key Features
Dynamic Movement Accommodation

Rotary Drilling Hose accommodates controlled displacement while maintaining continuous fluid transfer, making it ideal for systems experiencing vibration and equipment movement. The flexible hose body acts as a controlled movement section, reducing stress on pipe supports, flanges, valves, and equipment connections.

Marine Environmental Resistance

Designed for offshore conditions with durable rubber compounds and protective fittings that resist moisture, salt-containing air, sunlight, temperature variation, mud, oil, and continuous outdoor exposure. Proper material selection and installation practices ensure durable performance in demanding marine environments.

Fatigue Resistant Reinforcement System

Multiple reinforcement layers distribute internal pressure and mechanical forces throughout the hose wall, providing structural strength to manage pressure pulsation, bending, vibration, and tensile loading changes. Suitable reinforcement configuration ensures reliable long-term service performance.

Fluid Compatibility and Abrasion Protection

Inner tube materials selected for compatibility with various drilling fluids including water-based mud, oil-based mud, and synthetic drilling fluids. External cover provides abrasion protection against equipment contact and environmental exposure, ensuring both internal and external durability.

Applications
  • Semi-Submersible Drilling Units: Flexible high-pressure connections accommodating equipment vibration and relative movement in drilling fluid circulation systems
  • Offshore Jack-Up Drilling Rigs: Controlled flexibility connections between pumps, manifolds, pipework, and other components where rigid piping is unsuitable
  • Well Service and Offshore Support Equipment: Flexible high-pressure fluid connections for temporary or semi-permanent equipment arrangements requiring mobilization and relocation

Frequently Asked Questions
Is Rotary Drilling Hose suitable for offshore drilling applications?

Yes. Rotary Drilling Hose can be configured for offshore drilling applications where high-pressure flexible fluid transfer is required. The hose construction, rubber materials, reinforcement, outer cover, and metal fittings are selected according to the offshore operating environment, fluid medium, pressure, temperature, movement, and installation requirements.

How does equipment vibration affect the hose?

Continuous vibration creates repeated mechanical loading in the hose body and connection areas. A correctly specified flexible hose can accommodate controlled movement and vibration, but proper installation is crucial. The hose should have sufficient length, avoid torsion, maintain its specified bend radius, and be supported appropriately to prevent uncontrolled movement.

What information is needed to manufacture a customized Rotary Drilling Hose?

The most useful information includes hose nominal bore, overall length, working pressure, maximum temperature, conveyed fluid, end-fitting type, connection dimensions, fitting orientation, and installation environment. Existing hose drawings or equipment interface drawings can also be provided to help confirm the required assembly specifications.

How should offshore Rotary Drilling Hose be inspected?

Inspection should include the outer cover, hose body, connection areas, and visible fitting surfaces. Operators should look for deep abrasion, cuts, cracking, exposed reinforcement, abnormal deformation, leakage, fitting movement, or other unusual conditions. Inspection frequency should be determined according to operating severity and the customer's maintenance procedures.

Can the same Rotary Drilling Hose specification be repeatedly supplied for multiple drilling units?

Yes. Once the required technical parameters have been established and approved, the same specification can be used as a reference for repeat production. This includes hose bore, pressure rating, length, reinforcement construction, rubber material, fitting configuration, and testing requirements. Repeatable specifications simplify spare-parts management and planned maintenance for drilling contractors operating similar equipment.
