Industrial hoses play a major role in modern building services, enabling the safe and efficient transfer of air, water, chemicals, and waste across a range of applications. From heating and ventilation to plumbing and maintenance, the right hose specification ensures performance, safety, and compliance with building standards.
Key Types of Industrial Hose Used in Building Services
Building services rely on a variety of hose types, each selected for specific roles within mechanical, plumbing, and maintenance systems. These hoses are designed to withstand demanding conditions, including fluctuating pressures, exposure to chemicals, and constant handling.
Understanding which hose is appropriate depends on the medium being conveyed, the environment in which it operates, and the service life expected.
HVAC & Ventilation Hoses
In heating, ventilation, and air conditioning systems, hoses are used to manage airflow, connect ducting, and support equipment such as air handling units and fan coils. The priority in these applications is flexibility and resistance to temperature variations. Most HVAC hoses are lightweight, with smooth internal surfaces to minimise pressure drop and ensure efficient air movement.
We supply flexible ducting made from PVC or thermoplastic materials with reinforced wire helix for strength and shape retention. These hoses are typically rated for moderate pressure and temperature ranges, suitable for both supply and exhaust systems. Fire resistance, insulation, and anti-static properties may also be required depending on the installation environment.
Flexible Drain and Waste Hoses
Drain and waste hoses are essential for managing grey water, condensate, and discharge from equipment and plumbing systems. These hoses must be resistant to low-pressure fluid flow, abrasion, and, in some cases, mild chemicals or biological contaminants. In building services, they are typically installed in confined or hard-to-reach areas, so flexibility is very important.
PVC and rubber drain hoses are designed for durability and reliability in fixed and mobile setups. Reinforced options are available for installations where the hose may be subject to kinking or mechanical strain. Smooth-bore designs are often preferred to prevent sediment build up and allow consistent flow.
Chemical‑Resistant Hoses for Plumbing & Utility Systems
Chemical-resistant hoses are used where building services involve the transfer of aggressive cleaning agents, treatment chemicals, or other corrosive substances. These hoses must be compatible with the specific media in use and capable of maintaining integrity under pressure and varying temperatures.
We typically recommend hoses made from EPDM, nitrile, or specially formulated thermoplastics, depending on the chemical composition. Internal linings are selected for their resistance to permeation and breakdown, while the external layer must withstand contact with oils, UV exposure, and abrasion if used in plant rooms or exposed utility areas.
High‑Pressure Washdown and Maintenance Hoses
High-pressure washdown hoses are commonly used in building maintenance for cleaning plant areas, mechanical rooms, and external surfaces. These hoses are built to handle elevated pressure from pumps or mains supply and are often used with lances, nozzles, or trigger guns to direct flow.
Durability is a key requirement, as these hoses are frequently dragged across rough surfaces or exposed to sharp edges. We supply rubber and reinforced PVC options rated for pressure and temperature performance, with covers designed to resist abrasion, water ingress, and oil contact. Depending on the cleaning agents used, chemical compatibility may also need to be considered.
How to Choose the Right Industrial Hose for Building Services
Selecting the correct industrial hose for a building services application involves more than matching size and pressure ratings. Each hose must be chosen with its specific function, environment, and medium in mind. Misapplication can lead to premature wear, system inefficiency, or safety risks.
A thorough understanding of hose construction and selection criteria ensures the product performs reliably over its service life.
Understanding Hose Construction: Tube, Reinforcement, Cover
Every industrial hose used in building services is made up of three core elements: the inner tube, the reinforcement layer, and the outer cover. Each part plays a specific role in how the hose performs and how long it will last under operational stress.
The inner tube carries the medium and must be chemically compatible with it. Reinforcement gives the hose its pressure strength and flexibility, while the outer cover protects against wear, environmental exposure, and mechanical damage. The choice of materials and construction method directly influences suitability for different applications.
Core tube materials (rubber, PVC, thermoplastic)
The material used for the core tube determines the hose’s compatibility with the medium it carries. The choice often depends on whether the application involves air, water, chemicals, or waste.
Rubber is widely used for its flexibility and resistance to temperature extremes. It performs well in HVAC and washdown systems where durability and resilience are needed.
PVC is a lightweight, cost-effective option suited to lower pressure or drainage tasks, offering ease of handling and good chemical resistance.
Thermoplastics provide a balance of strength and chemical compatibility, particularly useful in systems handling treated water or cleaning solutions.
Reinforcement types (braided wire, spiral, textile)
The reinforcement layer provides the hose with its pressure handling capability and structural strength. Selecting the right reinforcement is essential to ensure the hose performs safely under working conditions.
Braided wire reinforcement is commonly used where high pressure and flexibility are both required, such as in washdown or maintenance hoses.
Spiral reinforcement, often made from high-tensile steel, offers even greater pressure resistance and is suited to heavy-duty applications with minimal flexing.
Textile reinforcement, using synthetic fibres, is typically found in medium-pressure hoses where weight reduction and ease of movement are priorities.
External covers (abrasion, ozone, UV resistant)
The outer cover is designed to shield the hose from environmental and mechanical damage, which can significantly impact its service life in its application. The operating environment often dictates the type of protection required.
In plant rooms or external installations, hoses may be exposed to sunlight, sharp edges, or oil residue. For these conditions, covers made from abrasion-resistant rubber or thermoplastic are preferred.
UV-resistant compounds prevent degradation from prolonged sun exposure, while ozone resistance is essential in areas with fluctuating temperatures or electrical equipment.
A well-specified cover helps maintain hose integrity without compromising flexibility.
STAMPED Selection Framework (Size, Temperature, Application, Medium, Pressure, Ends, Delivery)
The STAMPED method is a proven framework used across industry to correctly specify industrial hoses. It ensures all operational and environmental factors are considered before a hose is selected, reducing the risk of failure and improving system performance.
Size refers to the internal diameter and length required for the hose to perform without restricting flow or causing pressure loss.
Temperature accounts for both the internal medium and the external environment.
Application considers how the hose will be used, including any movement, routing, or installation constraints.
Medium focuses on chemical compatibility with the substance being transferred.
Pressure covers both working and burst ratings to ensure safety.
Ends refers to the fittings needed for connection, which must be suitable for the hose type and system.
Delivery relates to logistical considerations such as lead times or custom assemblies.
At Hoses Direct we use this framework to ensure that all hoses we supply, whether off the shelf or custom, are always fit for purpose to ensure you have the correct hose for the job no matter the application.
Industry Standards, Regulations & Performance Requirements
Industrial hoses must comply with a range of standards that govern safety, quality, and suitability for the intended medium. ISO 8330 provides the fundamental terminology and classification, while sector-specific documents such as ISO 6134 for steam hose or BS EN 694 for fire-resistant hose define performance criteria.
British Standards and the Health and Safety Executive require pressure safety factors, typically a minimum four-to-one ratio between working and burst pressure, so each hose must be factory-tested and certified before it reaches site.
For potable water systems, hoses should carry WRAS or equivalent approval to confirm material compatibility, whereas chemical service hoses must demonstrate resistance through material data and laboratory testing.
