GROOVED COMPONENTS

GASKETS

Gasket MaterialsCompound Grade Temperature Range General Service Applications

EPDM E -34 to110C Fire, HVAC, non petro applications, Oil-free Air, hot water service within the specified temperature etc

NBR D -29 to 82C Petroleum products applications, air with oil vapors, vegetable and mineral oils etc

SILICONE S -40 to 177C Air without petroleum, high temperature dry air and high temperature chemical products

Main component for a quality coupling is a premium Gasket

HOUSING

The Housing

Central produces ductile iron, ASTM A-536, Grade 65-45-12 for all of its grooved products. Once the base iron is produced, magnesium is added in precise measurements to develop the ductile iron grade. The metal is tested chemically, physically, and microscopically prior to being released for production. Once cast, the ductile iron is once again checked to ensure conformance with these specifications.

NUTS AND BOLTS

The Nuts and Bolts• Bolts and Nuts: Coupling bolts and nuts are heat treated

carbon steel, oval-neck track head bolts and heavy hex nuts, with bolts conforming to ASTM A-183 with a minimum tensile strength of 110,000 psi. Bolts and nuts are Zinc electroplated as per ASTM B633.

• Threads as per ANSI B1.1-1982, class2A & 2B• Must follow Torque Specification outlined in product data

Why use Grooved

3 Key Reasons

Reduces fabrication & installation time 50%Pace of Asia construction is 2X fasterOwners want a faster ROI, via occupancy

easierNo special skills required, anyone can learn & we will reach you - on site

saferNo welding fumes, minimizes fire hazardConstruction stops during fire investigationPotential to damage property & harm peopleRisk of increased insurance premium

Why Grooved?

• REDUCED INSTALLATION TIME .

Methods such as welding and soldering are labor-intensive and can be very time consuming . Pipe grooving reduces installation time by up to 80%, allowing contractors to save time/money and completing project within schedule.

• ACCOMODATES PIPE EXPANSION.

JINAN MEIDE -MECH flexible couplings are able to absorb linear movements of pipe work due to temperature changes, eliminating or minimizing the use of expansion joints.

• FLEXIBLE RETROFITS AND REPAIRS.

When an owner cannot afford to shut down a facility for important retrofits, JINAN MEIDE - MECH mechanical products solve the problem. MECH couplings and fittings allow an installer to fabricate onsite and around complex problems and obstacles. No fire permits are required and no welding fumes force building residents to evacuate.

• PRE –TESTED AND APPROVED FITTINGS

JINAN MEIDE -MECH fittings are tested and approved by International approval agencies like FM, UL, VdS, LPCB, Kite, PSI, ISO etc and reaches site with all approvals. Clients can be assured about the quality and reliability of MECH Brand Fittings.

Why Grooved?

NO SPECIAL TOOLS

Grooved products are assembled onto a standard groove. It does not require special tools or additional training to complete the job.

Why Grooved?

IDEAL FOR HAZARDOUS ENVIRONMENTS

Grooved pipe does not require welding, threading or cutting, which eliminates cutting oils, fumes, and flames. It is the ideal method for joining pipe in enclosed, flammable, or hazardous sites like tunnels and mines and doesn't require burn or hot-works permits.
