Non-metallic composite shut-off valves

Pipeline valves made of various polymers as well as composite materials are becoming more and more popular in modern industry. It is caused by obvious advantages of plastics in relation to traditionally used materials in a number of properties. The main properties are:

• high resistance to chemically aggressive media;
• absence of corrosion and wall deposits affecting the purity of transported liquids;
• long service life;
• low weight and easy installation;
• no maintenance costs;
• relatively low price.

Composite polymer pipe fittings

Along with plastic pipelines, polymer composite valves are widely used in various fields of energy, chemical, food and other industries, where acid and alkaline solutions, concentrated acids and alkalis are the main media transported through pipelines. Metal pipes and shut-off valves traditionally used for these purposes caused a lot of complaints regarding their corrosive properties and contamination of the environment, as well as short service life. Economically, the use of metal pipelines requires expensive corrosion protection, while quality metal shut-off and control valves are available on the market at prices 2.5-3 times higher than the cost of plastic valves of similar quality. The use of plastic pipelines and valves makes it possible to avoid these significant disadvantages.

As a result interest in polymer pipes and fittings is growing. During the construction of new facilities and modernisation of existing technological pipelines, companies take into account the existing experience and try to find new ways for minimising future costs and avoiding a number of old problems through the widespread introduction of plastic pipelines and fittings.

Constanta-2 LLC as a company specialising in the production of polymer products, offers shut-off valves made of polymer and composite materials of a significantly different quality level compared to plastic valves, widely spread in the local market.
