Introduction
Hegawa introduces the new "Fastfit Grip" pipe coupling and flange adaptors designed for PE and PVC pipes. These products offer pull-out resistance and are easy to install without special tools.

Technical Specifications
The coupling consists of a sleeve between two end-rings, with grip rings, press rings, and gaskets positioned in between. The end-rings are pressed onto the sleeve when bolts are tightened, ensuring a leak-tight seal due to the high-quality rubber gasket.

Features

Pre-assembled delivery, no dismantling required.
Minimal parts and no special tools needed.
Nut protection against turning during tightening.
Metal-to-metal contact indicates proper installation.
Designed for PE and PVC pipes, following DIN, BS, and ANSI standards.
No support liner necessary for PE/PVC PN 10/16 quality.

Material Specifications

End rings, press rings, sleeves, and adaptors: Ductile iron GGG 450-10.
Grip rings: Brass MS 58 up to DN 300.
Rubber gaskets: EPDM grade W.
Bolts and nuts: Dacromet coated steel, stainless steel available on request.
Coating: Dupont Alesta epoxy powder.

Product Range
Hegawa offers a range of couplings and adaptors for various pipe materials, including steel, ductile/cast iron, PVC, and PE, with working pressures up to 16 bars. The products are available with all flange drillings and are suitable for use in water, gas, and industrial applications.

Installation and Maintenance
The products are designed for easy installation under various conditions, including wet environments. They accommodate up to 50 mm longitudinal adjustment and simplify maintenance and future modifications.

Conclusion
Hegawa's pipeline products provide a reliable and efficient solution for connecting and maintaining pipelines across various applications, ensuring long-term performance and ease of use.

Flanged Dismantling Joints (Type HD-2)
These joints are available with flanges drilled to PN 10, PN 16, and PN 25, with other drillings available upon request. Dimensions are provided in millimeters. The document includes a detailed table listing nominal bore sizes, pressure ratings, and bolt specifications for various pipe sizes.

Compression Fittings
Hegawa Compression Fittings are suitable for steel, PVC, polyethylene, and copper pipes. They offer rapid installation, end load bearing, corrosion protection, and an optimal repair system. The fittings are available in sizes ranging from 3/8” to 2” and are made from malleable cast iron with NBR gaskets.

Expansion Joints
These joints are designed to absorb forces caused by changes in pipe length due to temperature variations. They are available in sizes from 50 mm to 600 mm and can be customized for specific applications. The document outlines the necessary data required for inquiries, including application details, pipe specifications, and special requirements.

Bell Joint Repair Clamps
These clamps provide a permanent repair solution for leaking spigot and socket joints. They are designed to be installed while the main line is pressurized and require no future maintenance. The document lists available sizes and material specifications, including galvanized steel bolts and ductile iron flanges.

Ductile Iron Repair Clamps
Designed for permanent repair of ductile iron, cast iron, and steel pipes, these clamps feature a 'waffle' type rubber with bridging plates for a leak-tight seal. They are easy to install and provide long-term corrosion protection. The document includes specifications for available sizes and working pressures.
