01
What It Is
Zinc-plated or stainless band clamps (W1 carbon / W4 SS304 / W5 SS316) with an EPDM rubber lining, bandwidth 20 / 25 mm, for pipe sizes 15-250 mm and larger.
CLAMPS AND COUPLINGS
Pipe Clamps and Couplings
Grooved couplings, quick joints, EPDM lined clamps and pipe clamps - weld-free joining and vibration-damped fixing, supplied as part of the one-stop piping package.
GROOVED COUPLINGS
Grooved Couplings
Rigid and flexible grooved couplings to AWWA C606 grooving dimensions; ductile iron ASTM A536, carbon steel and stainless bodies; UL 213 / FM 1680 listed options for fire protection.
Rigid Grooved Couplings
Angled bolt pads lock the pipe ends with no movement - a flange-like rigid joint for sprinkler head alignment, equipment connections and wider support spacing.
Flexible Grooved Couplings
Parallel bolt pads allow controlled linear and angular movement - absorbs thermal expansion, settlement, vibration and seismic displacement.
Gaskets and Coatings
EPDM gaskets for water and HVAC service (to about 120 degrees C), NBR for oil service; epoxy, hot-dip galvanized or natural stainless surfaces.
EPDM CLAMP
EPDM Clamps - the Rubber-Lined Focus Item
Rubber-lined suspension bands that isolate the pipe from the metal clamp.
02
Why EPDM
The liner isolates pipe from metal, absorbs vibration and water hammer, protects insulation and prevents galvanic corrosion - especially on stainless lines. Service from -40 to +120 degrees C.
03
Where It Wins
HVAC chilled and hot water, compressed air, fire sprinkler and sanitary stainless lines. Installation runs 30-50 percent faster than welded brackets.
QUICK JOINTS
Quick Joints and Camlock Couplings
Weld-free, thread-free connectors for fast assembly and repair.
Quick Pipe Couplings
Push-fit and press couplings for steel and stainless lines - no welding, no threading, fast repair and installation.
Camlock Couplings
Cam and groove quick couplings to A-A-59326 (3/4 to 6 inch) in stainless, aluminium and brass - standard for fuel, irrigation and water transfer.
No Hot Work
Quick joints need no hot-work permits and no welders - the practical answer for fire-fighting, mining, emergency and temporary pipelines.
PIPE CLAMPS
Single and Twin Pipe Clamps
Fixing pipes securely to brackets and structures.
01
Single and Twin Clamps
Single and twin clamps by pipe OD, with or without rubber inserts; standard and heavy series to DIN 3015 dimensions, galvanized carbon steel or stainless steel.
02
Complete Suspension
Supplied with weld plates, threaded rods and combi nuts - a complete pipe-hanging system coordinated with your pipe sizes.
03
Materials
Zinc-plated carbon steel as standard; SS304 / SS316 for corrosive, food and marine installations.
