Pipe Joint Blue Epoxy Coated Ductile Iron Wide Range Universal Coupling

Pipe Joint Blue Epoxy Coated Ductile Iron Wide Range Universal Coupling

Reliable Universal Coupling for Indian Water, Industrial & Infrastructure Pipelines

In modern Indian pipeline networks, flexibility, durability, and long service life are critical requirements.
The Pipe Joint Blue Epoxy Coated Ductile Iron Wide Range Universal Coupling is designed to meet
these exact needs across water supply, sewage, industrial, and infrastructure projects.
Manufactured using high-strength ductile iron and protected with a corrosion-resistant blue epoxy coating,
this universal coupling provides a dependable solution for joining pipes of different materials and outer diameters.

Krishna Industries, based in Ahmedabad, Gujarat, India, supplies high-quality
wide range universal couplings that comply with Indian site conditions, working pressures, and installation practices.
Our couplings are widely used across municipal water supply schemes, irrigation pipelines, industrial plants,
fire fighting networks, and infrastructure projects throughout India.

Introduction: What is a Wide Range Universal Coupling?

A wide range universal coupling is a mechanical pipe joint designed to connect pipes
with different outside diameters, materials, or tolerances. Unlike rigid couplings that require precise pipe dimensions,
a universal coupling offers flexibility and adaptability, making it ideal for repair works, retrofitting,
and new installations where pipe conditions may vary.

The Pipe Joint Blue Epoxy Coated Ductile Iron Wide Range Universal Coupling is specifically engineered
for Indian pipeline networks, where ductile iron pipes, MS pipes, CI pipes, PVC pipes, and HDPE pipes
often coexist within the same system.

Related products commonly used alongside this coupling include:
ductile iron dismantling joints,
flanged adaptor,
repair clamps,
DI pipe fittings, and
mechanical couplings.
These products together form a complete pipeline jointing and maintenance solution.

With increasing demand for long-life water infrastructure under schemes like
Jal Jeevan Mission, AMRUT, and industrial expansion across India,
the use of universal couplings has grown significantly due to their ease of installation, reduced downtime,
and compatibility with multiple pipe materials.

Product Description

The Pipe Joint Blue Epoxy Coated Ductile Iron Wide Range Universal Coupling supplied by Krishna Industries
is manufactured from high-grade ductile iron conforming to international and Indian quality standards.
The internal rubber gasket ensures a tight, leak-proof seal, while high-tensile fasteners provide
uniform pressure distribution around the pipe circumference.

The external surface is coated with fusion bonded epoxy (FBE) blue coating,
which offers excellent resistance against corrosion, soil chemicals, moisture, and water exposure.
This makes the coupling suitable for both underground and above-ground installations in Indian climatic conditions.

The wide range design allows a single coupling size to accommodate a large variation in pipe outer diameters,
reducing inventory requirements and simplifying procurement for contractors and project engineers.
