PVC-C water supply fittings

PVC-C water supply pipe fittings (PVC PVC water supply fittings) is a new generation of water supply system core components developed based on PVC-C resin chlorination modification technology, as a supporting connection unit of PVC-C water supply pipes, widely used in water supply transportation scenarios inside and outside buildings, industry and special fields, with excellent high temperature resistance, corrosion resistance, high strength and other characteristics, gradually replace traditional metal pipe fittings and ordinary plastic pipe fittings, and become the preferred solution for high-end water supply systems.

1. Product basic definition and core structure

1. Material properties and composition

PVC-C water supply fittings are made of chlorinated polyvinyl chloride (PVC-C) resin as the base material, and environmental protection additives (lead-free, heavy metal-free) such as stabilizers, antioxidants, and lubricants are added, and are integrated into the molding process through extrusion or injection molding process. Compared with ordinary PVC pipe fittings, the material density is increased to 1.45-1.55g/cm³, and the molecular stability is significantly enhanced, ensuring the high temperature resistance, corrosion resistance and mechanical properties of pipe fittings from the source.

2. Core structure design

Standardized connection structure: covering a full range of specifications such as straight through, elbow (45°/90°), tee (normal tee, reducing tee), cross, reducing joint, pipe cap, bow joint, etc., adapting to common pipe diameters such as DN15-DN200 to meet the connection needs of turning, diversion, reducer, plugging and other connections of the water supply system. The joint part adopts a socket design, and the inner wall is reserved for sealing grooves, which can be double sealed with special rubber sealing rings or PVC-C special glue to avoid the risk of water leakage.

2. Core performance: break through the technical advantages of traditional pipe fittings

1. High temperature resistance: Suitable for hot water and high-temperature environments

As a core highlight of PVC-C pipe fittings, it is resistant to temperature for a long timeIt has a capacity of up to 93°C and can withstand a short-term peak temperature of 110°C (for 1 hour), which is far better than ordinary PPR pipe fittings and PE pipe fittings. Even in the hot water circulation system or buried cement cushion, the pipe fittings can maintain structural stability without softening, cracking, etc., solving the pain point of traditional plastic pipe fittings "afraid of high temperatures".

3. Applicable scenarios: covering the needs of water supply in multiple fields

1. Civil construction sector

Residential water supply system: Adapt to the secondary water supply (from the water tank to the user) and the solar/air energy hot water circulation pipeline of high-rise residences to solve the problems of high water pressure and hot water temperature fluctuations, and match the service life of pipe fittings with the life of the main building (50 years), reducing the cost of later replacement and maintenance.

Public building water supply: used for purified water delivery in hospital operating rooms, drinking water pipelines in school canteens, and hot water supply systems in hotels, with hygiene and flame retardant properties that meet the strict requirements of public places, such as in hospitals, which can withstand regular high-temperature disinfection (80°C hot water rinsing) and do not release harmful substances.

2. Special scene adaptation

High-temperature water supply scenarios: such as hot water transmission pipelines in hot spring resorts and water supply pipelines for industrial waste heat recovery systems, high-temperature resistance avoids water leakage caused by high-temperature softening of pipe fittings.

High-pressure water supply scenarios: For example, the centralized water supply system of a large complex or the water supply pipeline of high-pressure cleaning equipment in a factory ensures that the pipe fittings do not rupture under high pressure.

PVC-C water supply pipe fittings achieve the four core advantages of "high temperature resistance, corrosion resistance, high strength, hygiene and environmental protection" through "material modification, structural optimization, and process upgrading", which not only solves the problems of easy corrosion, large weight, and complex installation of traditional metal pipe fittings, but also makes up for the shortcomings of poor temperature resistance and low pressure bearing of ordinary plastic pipe fittings. In practical applications, it can not only ensure the long-term stable operation of the water supply system, but also reduce the whole life cycle cost through the characteristics of "long life and low maintenance", which is an ideal choice for water supply system upgrades in civil buildings, industrial production, municipal engineering and other fields.
