This document outlines guidelines for the installation and maintenance of thermoplastic hoses, emphasizing the importance of proper selection, installation, and maintenance to ensure safety and longevity.
Users are responsible for determining the suitability of Transfer Oil products for their specific applications. It is essential to consult technical literature and seek clarification from the Transfer Oil sales department if needed.
Regular maintenance and inspection of hose assemblies are crucial to prevent dangerous failures. Users should establish a program for regular inspection, testing, and replacement of hoses, considering factors like application severity and equipment usage frequency.
Users must adhere to safety precautions, such as using shields near pressurized lines, wearing safety glasses, and avoiding direct contact with pressurized hoses. Immediate medical attention is necessary if fluid punctures the skin.
Hoses should be selected based on system pressure, temperature, and fluid compatibility. Avoid exceeding maximum operating pressures and temperatures to prevent deterioration and reduced service life.
Hoses must withstand system pressures and temperatures without exceeding recommended limits. Continuous use at maximum ratings should be avoided to prevent deterioration.
Hose materials must be compatible with the fluids used. Permeation of gases and liquids can occur, potentially leading to hazardous conditions.
Proper routing and protection of hoses are necessary to prevent damage from excessive flexing, abrasion, or contact with corrosive materials. Use clamps and guides as needed.
Failure to adhere to proper procedures can result in premature failures and safety hazards. Users must ensure compliance with all guidelines to maintain safe and effective hose installations.
Ensure the service temperature of the fluid and the ambient temperature do not exceed the hose limits. Special attention is needed if the hose passes near hot collectors or molten metals.
The hose selection must consider the compatibility of the substrate, coating, reinforcement, and fittings with the fluid. Special care is needed for gas transport, and some fire-resistant fluids may require the same hose used for mineral oil.
Gas or fluid leakage from inside to outside can occur, especially with gases, fuels, solvents, and refrigerants. This can lead to potentially flammable, explosive, or toxic vapor concentrations and fluid loss.
Choose the path carefully to minimize issues. Secure, protect, or guide the hose using clamps if necessary to reduce damage risks from excessive bending, whiplash, or contact with moving parts.
Ensure hose and fittings are compatible with or protected from environmental conditions like UV light, heat, ozone, moisture, water, salt water, chemicals, and pollutants, which can cause degradation.
Sudden escape of refrigerant gases can cause blindness or severe injuries. Special care is needed in refrigeration systems.
Avoid exposing hose assemblies to atomic radiation due to unknown long-term effects.
External forces like excessive flexing, twisting, kinking, tensile or side loads, bend radius, and vibration can reduce hose life. Swivel fittings or adaptors may be required.
In applications like autoclaves or underwater, external pressures may exceed internal fluid pressure. Consider these pressures and consult manufacturers if necessary.
Protect the hose from excessive abrasion to prevent erosion, snagging, and cutting of the hose cover.
Ensure compatibility between hose and coupling based on manufacturer recommendations.
Proper training and adherence to manufacturer instructions are vital for hose assembly integrity.
Consider motion absorption, pressure-induced length changes, and machine tolerances when determining hose length.
Review applicable government, industry, and manufacturer specifications and recommendations when selecting hose and fittings.
Some applications require non-conductive hoses to prevent electrical current flow, while others require conductive hoses to drain static electricity. Extreme care is needed in selection.
Fluid passing through the hose can generate static electricity, potentially causing sparks. Select hoses with sufficient conductivity to ground the charge.
Avoid installing hoses at less than the minimum bend radius to prevent reduced hose life.
Ensure hose installations do not produce twisting due to machine component motion.
Restrain, protect, or guide hoses to prevent damage from unnecessary flexing or pressure surges.
Ensure correct port connection without transferring twist or torque to the hose.
Correct or eliminate tensile loads, side loads, kinking, flattening, potential abrasion, thread damage, or damage to sealing surfaces.
Do not use hoses for purposes that apply external forces for which they were not designed.
Establish a maintenance program to include visual inspections for damage, leaks, and other issues. Immediate shutdown and replacement are required for damaged, cut, or abraded covers, exposed reinforcement, cracked or corroded fittings, and leaks.
Regular visual inspections are crucial for maintaining hose and fitting integrity. Immediate replacement is necessary if any of the following conditions are observed: damaged, cut, or abraded cover; hard, rigid, cracked, or burnt hose; cracked, damaged, or corroded fittings; leaks at fittings or hose; twisted, split, crushed, or kinked hose; blistered, soft, degraded, or loose cover.
Ensure all components are tightened, repaired, or replaced as needed. This includes addressing leaking port conditions, clamps, guards, shields, system fluid levels, fluid type, and air entrapment. Excess dirt build-up should be removed.
Replacement intervals should be based on previous service life, government or industry recommendations, or when failures could lead to unacceptable downtime, damage, or injury risk.
Correct installation is essential to avoid additional stress or wear points. Ensure hoses are connected properly at all passage points without transmitting torsional forces. Avoid external damage by ensuring no longitudinal or transverse loads, twisting, crushing, potential abrasions, thread damage, or sealing surface damage are present.
Hoses and fittings are designed primarily for internal fluid forces. Avoid using hoses in ways that apply external forces for which they are not designed.
Even with proper selection and installation, hose life can be significantly reduced without a regular maintenance program. The frequency of maintenance should be determined by the application's criticality and potential risk. A maintenance program should include visual inspections and addressing any identified issues promptly.
Allow sufficient slack for expansion and contraction due to high-pressure surges. Hoses should exit couplings in a straight position, and the minimum bend radius must not be exceeded to avoid kinking and flow restriction. Use proper angle adapters to avoid sharp twists or bends. Design installations to produce bending rather than torsion to prevent weakening and fatigue.
Proper hose installation is crucial for satisfactory performance and appearance. Excessive length can increase costs and affect appearance, while insufficient length can lead to poor power transmission and reduced hose life. Diagrams provide suggestions for optimal hose installations to maximize performance and economy.
