ROMAC ALPHA RESTRAINT COUPLING

Gathering the appropriate materials is a known rule in finishing a task quickly. What if it’s possible to utilize a single coupling for different materials that is able to produce remarkable results and generate a long-lasting trusted performance? Availing such convenience would require you to be informed with Cohen Pipe’s Restraint Couplings. Below are some information that could contribute to providing you information on restraint couplings of excellent quality.

Needless to say, time is equivalent to money. It may seem to be a simple statement but would cost you. Discovering new Cohen products was a total game-changer since it meant better offers for the customers. It is of useful advantage having the ability of installing a coupling quickly without the need of getting the right size fitting for the truck since you can accomplish the job in the nick of time.

The Cohen premium coupling is a diverse, 3 minute-installation restrained coupling which only requires tightening of two nuts. Achieving the fully restrained joint that has a maximum pressure of 350 psi involves the processes of slipping the coupling over the pipe gap then tightening the nuts to the right ft-lbs.

VERSATILITY IN SELECTING MATERIALS

The ALPHA inlet is perfectly fit for several types of materials such as ductile and cast irons or HDPE and PVC pipes which explains that it is flexible with every pipe material used in waterworks systems.

QUICK INSTALLATION PERIOD

Installation procedures of standard mechanical joints are very slow since they require eight bolts per end. With the ALPHA joints, it only consists of a top-mounted stainless steel bolt, thus, making it more cost-efficient and effortless.

ALREADY PRE-ASSEMBLED FOR YOULATION PERIOD

Installing the mechanical joint upon its arrival to your area is time-consuming. The difference with the ALPHA is that you receive the items already pre-assembled and would only need minimal adjustments done to complete the installation.

WORKPLACE AVAILABILITY

Tightening bottom bolts on mechanical joints indeed is a troublesome work but with the ALPHA joint containing the easy-to-reach bolts, it makes it more accessible than other applications. Furthermore, the ALPHA can be assembled by an individual unlike the mechanical joint valves which may sometimes need another person to finish the process.

EASY INSTALLATION

The ALPHA doesn’t need fasteners since it operates with the water pressure present in your system and decreases the torque in order to reach a fixed restraint connection. Also, it has a triple O-ring stem seals, thrust washers and a secure 100% tight closure that prevents leakages.

ALPHA is a US-manufactured selection of products from Romac Industries that offers a wide range of commonly used pipe equipment and other materials ranging from ductile iron to IPS PVC pipe diameters. Cohen has partnered with ALPHA to bring better services to customers and make the installation processes more efficient. Providing assistance on suggesting the best solutions to water utility problems are their priority. Their contact line support is open for customers who would want to inquire or explore more of ALPHA’s features.
Repair couplings WA-RP-UN units have dual purposes: installation and repair of pipe leakages.

Non-restraint couplings are utilized for linking and/or covering metal and plastic pages that were damaged in the long run. Those units can be pulled effortlessly around a leaking pipe and shut tightly to cover a fracture.

Repairs are allowed to be done carefully and immediately with pipes left in service.

Repair couplings are fit for sudden repairs in large institutions caused by damages resulting from water leakages.

The repair made on the WA-RP-UN pipe repair clamps to a pipeline are permanent while the line stays during the entire process.

Pipe repair clamps may be suitable for use on steel and cats irons and PE or PVC pipes

EDPM and NBR seals are considered standard materials while VIton and Silicone seals are readily available in our shops. WA-RP-UN repair clamps are applicable for use on different operational water pressure lines based on the pipe size.

Split repair couplings are acceptable for emergency and permanent connection repairs found in water utility systems.

 

Restraint Coupling 316L
Stainless steel, WA-RC-UN coupling

A restraint coupling design provides excellent security through closing pipes under pressure at the same time. Special-shaped balls move the hardened restrained teeth towards the surface of the pipe when the central weight of the pipe increases due to internal pressure or outside factors.

Enhances attaching on hard surfaces such as stainless steel or ductile iron pipes. The teeth angles ensure a grip on various surfaces similar to galvanized steel and others.

PIPE COUPLINGS - PIPE CONNECTORS

Pipe couplings WA-PC units provide pipeline flexes with diameters ranging up to 158” or 4000 mm.

The housing is made of stainless 316 L material with high durability design. WA-PC-Flex couplings allow weight savings on top of cast iron couplings.
