Product Overview

TheHigh Toughness Cast Iron Rigid Coupling is a high-quality grooved pipe fitting designed for fast, boleh dipercayai, and leak-proof connections in low-pressure piping systems. Manufactured from high-strength ductile/cast iron with a zinc-plated surface treatment, this coupling provides excellent corrosion resistance, ketahanan, and long service life in demanding applications. The grooved connection design enables quick installation without threading or welding — simply align the coupling over the grooved pipe ends and tighten the bolts. Available in sizes ranging from 76mm to 165mm (3″ to 6″) with custom options, this rigid coupling is widely used in water supply, pipeline systems, minyak & gas, dan aplikasi perindustrian. With UL and CE certifications, it meets international safety and quality standards. Backed by a 3-year warranty and OEM/ODM/OBM customization support, it is a reliable and cost-effective solution for pipeline connections.

FAQ

S1: What is the difference between rigid couplings and flexible couplings?

A: Rigid couplings provide a fixed, stiff connection that does not allow for angular deflection or axial movement; they are suitable for piping systems requiring precise alignment. Flexible couplings allow for limited angular deflection (typically 3–5 degrees) and axial movement, making them suitable for piping systems subject to settlement or vibration.

S2: What is the maximum working pressure for this coupling?

A: This rigid coupling is designed for low-pressure applications. The specific working pressure depends on pipe size and installation conditions. Please refer to the product data sheet for detailed pressure rating information.

S3: What are the advantages of a galvanized finish?

A: A galvanized finish provides excellent rust and corrosion protection, making it particularly suitable for outdoor installations, humid environments, and water supply systems. It significantly extends the product’s service life and reduces maintenance costs.

S4: How do I install grooved rigid couplings?

A: Installation steps: 1) Clean the pipe ends and grooves; 2) Fit the gasket onto the pipe ends; 3) Position the coupling housings over the gasket; 4) Insert the bolts and tighten them alternately to the specified torque. No welding or threading is required, making installation quick and easy.
