Oil & Gas HOSE ASSEMBLY & CRIMPING SOLUTIONS

Composite Hoses, Industrial Rubber Hoses, and High-Performance Swaging Systems

One: Introduction of Composite Hoses in Oil & Gas

Composite hoses can be used for the transportation of petroleum and petrochemical products, such as crude oil, fuel oil, lubricants, natural gas, liquefied petroleum gas, and more.

The relationship between Composite Hose and the Oil & Gas industry is one of "tailor-made" solutions provider and demanding application areas. It is not merely a simple connection tool, but a core safety component ensuring the safe, efficient, and environmentally friendly transmission of energy. Its multi-layered composite technology directly addresses the industry's four core demands for safety, flexibility, durability, and environmental friendliness, securing its irreplaceable position in modern oil and gas storage and transportation systems.

Two: Specific Application Scenarios in the Oil & Gas Supply Chain

❶ Marine Loading/Discharge: Loading and unloading of crude oil, refined oil products, and LNG/LPG (liquefied natural gas/petroleum gas). This is the most classic application of composite hoses.

❷ Terminal & Storage: Used for tank transfers, filling/unloading of road or rail tank cars.

❸ Fuel Dispensing: Used for connecting underground storage tanks to refueling pumps; oil-resistant and anti-static.

❹ Upstream E&P: Used for chemical addition, fuel delivery, and temporary crude oil or produced water treatment pipelines on drilling platforms.

❺ Into-plane Refueling: The hoses connecting aircraft refueling trucks to the wings have extremely high requirements—they must be lightweight, flexible, clean, and safe.

❻ Emergency Response: Used for oil spill recovery, temporary containment, or emergency bypasses due to their rapid deployment and adaptability.

①Composite hoses are flexible pipelines manufactured using multi-layer composite technology. Their unique structure enables the safe and efficient transport of oil, natural gas, and their derivatives, solving many pain points of traditional pipelines in terms of safety, corrosion resistance, flexibility, and weight. They are indispensable critical fluid transport pipelines in the oil and gas industry.

②Industrial Rubber Hoses

Standard industrial hoses used in oilfield services (e.g., fuel suction and discharge, mud hoses) are typically reinforced with high-tensile textile or steel wire. The connection between the hose and the coupling (Camlock, Flange, or Hammer Union) determines the safety of the entire transfer line.

Three: The Role of Hydraulic Crimping Machines

Precision Crimping / Swaging Systems

In the Oil & Gas sector, a generic crimper is insufficient. Specialized Industrial Hose Crimping Machines (often with 100 to 600 tons of force) are required to:

❶Maintain Concentricity: Ensuring the fitting is perfectly centered to prevent uneven pressure distribution.

❷Manage Radial Force: Applying consistent pressure across large diameters (up to 10" or 12" for dock hoses).

❸Execute Programmable Logic: Modern machines use PLC controls to stop at an exact "Final Crimp Diameter" to avoid over-compression.

Four: Technical Validation: The Crimp Diameter

In Oil & Gas applications, a wall compression of 15% to 25% is common for rubber hoses, whereas composite hoses require specific technical charts provided by the manufacturer to ensure the "seal-side" and "wire-side" are both secure.

Five: Comparison: Composite vs. Industrial Crimping

Six: Safety and Certification

All assemblies for Oil & Gas must undergo Electrical Continuity Testing (especially for composite hoses to discharge static) and Hydrostatic Pressure Testing. The crimping machine’s calibration is critical to meeting API (American Petroleum Institute) and ISO safety standards.
