Fabricated PVC fittings are custom-shaped fittings, often for larger diameters, made by cutting, bonding, and thermoforming segments of existing PVC pipes, resulting in a homogeneous, high-strength structure suitable for various pressures. Key specifications include the dimensional ratio (DR) for pressure, the material standard (e.g., AWWA C900 or C905), and the joint type (e.g., push-on or solvent-weld). Common examples include tees, bends, and crosses, with custom shapes available. Description Manufacturing Process: Fabricated fittings are not molded but are instead assembled from pieces of standard PVC pipe that have already undergone factory testing. Segments are cut, shaped (often by thermoforming), and then joined together under controlled conditions. Structure: The resulting structure is designed to be essentially a single, homogeneous piece of PVC, sometimes with added reinforcement bonded to its outer surface. Application: Fabricated fittings are frequently used for larger pipe diameters (typically above 12 inches) where molding is less practical. They are engineered for specific applications, such as higher-pressure water systems or sewer force mains. Key Specifications Material Standard: Fittings must conform to or exceed the requirements of relevant standards, such as AWWA C900 or C905 for water systems. Dimensional Ratio (DR): This indicates the fitting's pressure rating, with higher numbers signifying lower pressure capabilities. Joint Types: Push-On (Gasketed): Features a gasket for a tight, leak-proof connection, often used in water distribution. Solvent-Weld (Socketed): Requires primer and solvent cement for a chemically bonded joint, common in many plumbing applications. Restrained Joint: A specialized joint designed to prevent joint separation under pressure. Pipe Material: The fittings are made from PVC pipe that has already met the applicable pipeline standards. Customization: Manufacturers can produce custom-shaped fabricated fittings, such as specific bends or complex configurations, to meet project requirements.
