Product Description

Our grooved coupling pipe fittings are crafted from high - quality ductile iron, conforming to ASTM A536 standards. Ductile iron is renowned for its exceptional mechanical properties. It combines the strength of cast iron with the malleability of steel, making it an ideal material for applications that require durability and resistance to harsh conditions. The unique graphite microstructure in ductile iron provides excellent shock absorption capabilities. This means that in the event of sudden pressure surges or vibrations, which can occur during a fire emergency when water is being rapidly pumped through the system, the fittings can withstand these forces without cracking or failing. Additionally, ductile iron has a high resistance to corrosion. In fire fighting systems, where the pipes are often exposed to moisture and sometimes even corrosive substances in the water, the corrosion - resistant nature of ductile iron ensures a long - lasting service life. This reduces the need for frequent replacements and maintenance, ultimately saving costs in the long run.

We use EPDM (Ethylene - Propylene - Diene Monomer) gaskets in our grooved coupling pipe fittings. EPDM is a synthetic rubber that has excellent resistance to a wide range of environmental factors. It is highly resistant to water, which is obviously a key requirement in fire fighting systems where the fittings will be constantly in contact with water. EPDM also has good resistance to ozone, sunlight, and temperature variations. This means that the gaskets can maintain their elasticity and sealing properties over a long period, even when exposed to harsh outdoor conditions or fluctuating temperatures within a building. The chemical resistance of EPDM is another important factor. In some cases, fire - suppressing agents may contain chemicals that could potentially degrade the gasket material. However, EPDM's resistance to a variety of chemicals ensures that the gaskets remain effective and do not compromise the integrity of the connection.
