Author : kisan Group | Published On : 14 Oct 2026

Fabricated Fittings are pipe components manufactured to connect, redirect, or repair pipelines in water supply, irrigation, and infrastructure systems. Choosing the correct fitting requires checking pipe diameter, pressure rating, material compatibility, and installation conditions.

For projects using rigid uPVC pipelines, properly specified fittings help create practical connections while maintaining the intended pipeline configuration. Kisan Group offers fabricated elbows, couplers, and RRJ couplers manufactured according to IS 10124 Part 2, using rigid uPVC pipes specified to IS 4985. Its published range covers several diameters and pressure classes, giving contractors and engineers documented specifications to evaluate before procurement.

Key Features & Benefits of Fabricated Fittings

• Practical pipeline connections: Fabricated couplers connect compatible PVC pipe sections, supporting new installations and pipeline extensions.
• Efficient directional changes: Fabricated elbows allow a 90-degree change in pipeline direction without requiring a complex pipe arrangement.
• Pipeline repair support: RRJ couplers are included in Kisan Group's range for repairing damaged pipeline sections.
• Multiple size options: The published product range covers diameters from 20 mm to 400 mm, depending on fitting type and pressure rating.
• Documented manufacturing specifications: Kisan Group states that its fabricated products follow IS 10124 Part 2 and use rigid uPVC pipes manufactured to IS 4985.
• Application flexibility: Different fittings can be selected for compatible water supply, agricultural irrigation, and infrastructure pipelines.
• Pressure-based selection: Published pressure options allow engineers to shortlist fittings against the project's design requirements.

Ideal for These Applications

Water supply contractors: Fabricated pipe fittings are suitable for consideration when planning compatible uPVC water distribution networks that require directional changes, pipe connections, or repairs.

Agricultural irrigation projects: Farmers, irrigation contractors, and system designers can use appropriately rated fittings when extending or modifying rigid PVC water pipelines.

Infrastructure developers: Projects involving larger-diameter pipelines may benefit from a fabricated fitting range with clearly documented size and pressure options.

Maintenance teams: Repair-oriented couplers can help address damaged pipe sections when selected and installed according to the relevant specifications.

Who Should Consider Alternatives?

Fabricated uPVC fittings are not automatically suitable for every piping application.

Projects carrying hot fluids, aggressive chemicals, or operating beyond the selected fitting's pressure or temperature limits require a separate material and engineering assessment.

Similarly, a fabricated fitting should not be substituted for a different joining system without checking dimensional compatibility, joint design, and installation requirements.

For specialized applications, engineers should select components based on actual service conditions rather than product category alone.

Detailed Specifications: How Fabricated Fittings Work

The function of a fabricated fitting depends on its design. Elbows redirect water flow, couplers connect pipe sections, and RRJ couplers provide a repair-oriented connection option.

1. Fabricated Elbow Fittings

A fabricated elbow changes the direction of a pipeline, commonly by 90 degrees. It is useful where water supply or irrigation pipelines need to turn around structural or geographical obstacles.

Before selecting an elbow, verify the diameter, pressure class, joint requirements, and installation space.

2. Fabricated PVC Couplers

PVC couplers connect two compatible pipe sections. They are used during pipeline extensions, new installations, and certain maintenance operations.

Correct pipe alignment and the specified joining method are essential for a reliable connection.

3. RRJ Coupler Fittings

RRJ couplers are included in Kisan Group's fabricated fitting range for pipeline repair applications.

Selection should account for the pipe's outside diameter, joint configuration, sealing components, and pressure requirements.
