Natural gas hoses

What are the requirements for natural gas pipes?

Pipes intended for natural gas are subject to extremely strict requirements in terms of tightness, pressure resistance, temperature resistance, and chemical resistance. They must be certified in accordance with European Union or national standards, clearly marked, and comply with technical regulations for gas appliances. Gas hoses must not allow gas to pass through the wall, must be resistant to ageing, UV rays and fire, and their connection points must ensure complete tightness.

How to choose the right hose for the pressure and temperature?

When choosing a natural gas hose, it is necessary to take into account the pressure and operating temperature of the gas supply system. Most domestic hoses are suitable for operating pressures up to 0.5 bar and temperatures between 70 and 90 °C, but industrial models may be designed for higher parameters. Hoses are made of special nitrile (NBR) or EPDM rubber, which is resistant to gas and heat. It is important to choose only hoses that meet the manufacturer’s technical requirements and equipment specifications.

Resistance to chemical agents and mechanical damage

Since gas hoses are often used in various environments, both indoors and outdoors, it is necessary to ensure resistance to aggressive agents. Special surface layers protect the hose from petroleum products, grease, UV rays, temperature fluctuations, and mechanical wear. Reinforced outer jackets (textile or metal) increase resistance to bending, pressure, and abrasion, allowing the hose to retain its shape and tightness for longer.

Installation and maintenance of natural gas hoses

Proper installation and regular maintenance are key factors in ensuring the safety and longevity of gas hoses. Even the highest quality hose cannot guarantee risk-free operation if it is installed incorrectly or used for too long without inspection.

How to ensure a tight connection and prevent gas leaks?

Certified connecting elements must be used at connection points and the installation instructions must be followed. Fastening must be carried out without bending or stretching – the hose must not be overstretched or twisted. When using sealing elements (e.g., nuts with washers), make sure that the connections are tightened according to the manufacturer’s instructions. After installation, it is recommended to test the gas tightness with soap foam or a special leak detector.

When should an old hose be replaced with a new one?

Although most household hoses can last for 5–10 years, it is recommended to replace them every 3–5 years, especially if they are used intensively or outdoors. Visible cracks, hardened rubber, deformation, or discoloration are signs that the hose needs to be replaced immediately. Regular inspection of the hose condition can prevent potential accidents and ensure system safety.

How to perform a regular hose inspection for possible damage?

A visual inspection should be performed at least once every few months. Check for cracks on the surface, damage to the joints, and clarity of markings. You can also use testing tools that measure pressure and detect microcracks. Any suspicion of damage is a signal to stop using the hose immediately and replace it.
