Five Things to Keep in Mind When Using High-Pressure Steel-Wire-Braided Rubber Hoses

Five key considerations when using high-pressure steel-wire‑reinforced rubber hoses Failure to observe these precautions can severely compromise the hose’s performance and service life, potentially leading to serious accidents and financial losses. Below, we’ll outline the important safety tips for using high-pressure rubber hoses.

What are the structural characteristics of large-diameter high-pressure hoses?

Large-diameter high-pressure hoses are a type of hose, distinguished primarily by their relatively large nominal diameter. They are suitable for conveying hydraulic fluids such as alcohol, hydraulic oil, fuel oil, lubricating oil, water, emulsions, and hydrocarbons, enabling high-pressure fluid transport or hydraulic power transmission.

Structure of Large-Diameter High-Pressure Rubber Hoses and Points to Note During Use

Large‑diameter high‑pressure hoses shall not be used under torsional stress; they must be handled with care, and must not be dragged across sharp or rough surfaces, nor bent or crushed. Keep them clean and flush the interior thoroughly—especially for acid‑resistant hoses, spray lines, and mortar‑delivery pipes. Prevent foreign objects from entering the hose lumen, as such obstructions can impede fluid flow and damage the equipment. Hoses that have exceeded their service life or storage period may only be reused after passing a prescribed test and certification.

What are the common causes of damage to high-pressure steel-wire-reinforced hoses?

What are the common causes of damage to high-pressure steel-wire‑reinforced hoses? If the crimping depth and crimping speed selected during installation of rubber hoses and fittings are inappropriate, or if the fitting’s design, materials, and specifications are not properly chosen, the hose and fitting may be crimped either too tightly or too loosely, leading to premature failure at the joint.

What are the applications of high-pressure hoses?

High-pressure hoses are primarily composed of a liquid‑resistant styrene–butadiene rubber inner liner, an intermediate rubber layer, one to three layers of manually braided stainless‑steel wire, and a weather‑resistant styrene–butadiene rubber outer cover. The inner liner ensures the conveyed medium is contained and protects the stainless‑steel wires from corrosion, while the outer cover safeguards the wires from mechanical damage. The stainless‑steel wire layers serve as the structural reinforcement. These hoses are manufactured using a specialized formulation of styrene–butadiene rubber, offering excellent resistance to acids and alkalis, high temperatures, and aging.

What is the production process for high-pressure hoses?

There are numerous types of equipment for manufacturing high-pressure hoses, a wide variety of raw materials, and complex production processes. However, in recent years, the production process for high-pressure flexible hoses made primarily from plastics or thermoplastic elastomers has been somewhat simplified; yet, due to the relatively high cost of these alternative materials, rubber-based formulations still dominate. So, what is the primary production process for high-pressure hoses?

Key Considerations for the Working Pressure of High-Pressure Hoses

Each high-pressure hose has a specified working pressure, and its burst pressure is typically 3 to 4 times the working pressure. The higher the pressure, the more layers of reinforcement are required, and the stricter the manufacturing standards become. Therefore, based on the system’s actual operating pressure, selecting a high-pressure hose with a higher rated working pressure ensures normal system operation, allowing for appropriate use of the hose.

Applications, Maintenance, and Use of High-Pressure Rubber Hoses in Automobiles

Hoses are pipelines used for conveying gases and are commonly employed in gas cutting, gas welding, plasma arc welding, as well as various gas‑shielded welding and cutting processes. There are two types of high‑pressure hoses for welding: the red hose is for oxygen, with a maximum pressure rating of 1.5 MPa; the green or black hose is for acetylene and can operate at pressures ranging from 0.5 to 1.0 MPa. High‑pressure hoses are characterized by their physiological inertness, resistance to ultraviolet radiation, ozone, high and low temperatures, transparency, elasticity, compressibility, resistance to permanent deformation, oil resistance, impact resistance, acid resistance, wear resistance, flame retardancy, pressure resistance, and electrical conductivity.
