Grooved couplings and fittings

Our grooved products are made conform to the ASTM 356-45-12 standard and in conformity with the QT450-12 procedure. Grooved material is available in the following coatings: painted, epoxy, dacromet and galvanized. They are available in the colors red (RAL300), orange, white and blue. Painted and epoxy coated products are only suitable for low to medium heated water.

Flexible Hoses

In shallow spaces with low ceilings, barriers like walls, chimneys and cable trays, it might be difficult and time-consuming to fit sprinklers with pipes, tubes and couplings. By using flexible sprinkler drops you can quickly and easily install the sprinkler to your conduit.

Our hoses vary in length from 700 to 1800 mm, either braided (FM/VdS) or unbraided (UL, LPCB). Our hoses have nuts where the sprinkler nipples can be fitted easily. For the sprinkler nipple you have the choice between NPT and BSPT thread, with a diameter of 3/8”, 1/2”; 3/4” and 1”. We have sprinklers nipples in all kinds of sizes ranging from small (65mm) to large (400mm). For standard and special ceilings, we have a large assortment of accessories with the fixing material that can be customized to your demands.

If you need a 100% watertight solution, we can offer you a welded hose. Depending on a minimal friction loss with a 40ft pipe equivalent we can provide hoses with a bigger diameter up to 9/8″ and 5/4″.

For specific applications in laboratories, dust free, microbe-free spaces and low-pressure cabins, we have cleanroom hoses in our assortment. We have suitable connectors for any kind of ceiling to ensure the outlet reducer can be installed quick and easy. If you need a tailor-made reducer, we are happy to design and produce it based on your requirements.

In hazardous environments, you can use our flexible explosion proof hoses to protect your data cables, wires, or flammable fluids. Our hoses are also flameproof.

In non-statical mechanical applications like machine rooms, the movement of machines and pumps can generate all kinds of forces. Torsion, pulling and pushing forces may jeopardize your piping system. Bellows, shock absorbers, springs and water hammers can effectively neutralize these unwanted forces.

Flanges

We are specialized in flanges and offer flanges, fixed flanges, compression or adapter flanges. We are sure that we can provide any flanges that you might be searching for. We deliver the flanges in various versions (DIN, ASTM, STS) in various sizes from DN15 through DN400 (1/2″-16″). For all the flanges we offer, we keep the gaskets and seals in stock for you.

Sprinklers

Our sprinklers are designed to meet various customer requirements. Instead of a conventional fuse, our glass bulb contains a special liquid. This type of glass bulb simplifies the sprinkler structure and ensures stable operation in various circumstances and temperatures.

Our concealed sprinklers are designed to meet both aesthetic and practical requirements for airports, high-class hotels, shopping malls, offices and sports facilities. The unique design allows sprinklers to be hidden behind a provided cover plate. This plate has a 10mm field adjustment capability providing easy assembly and a tight fit against the ceiling.

Flush type sprinklers are designed to harmonize with any interior design. Because of our precise deflector design and patented heat collecting technology, it has an outstanding fast and accurate performance while also having a small body. Residential type sprinklers are designed to offer a fast response. It provides appropriate discharge and spray patterns to suppress the fire in a residential area. This offers a wider discharge angle that even cover the walls. Mainly installed in apartments, multi-service business centers and houses.

A fusible type sprinkler is a stable and simple sprinkler. These sprinklers are available in a horizontal and vertical version. It offers rectangular spray pattern and is ideal for use in hand-to-install areas such as fire-prevention shutter sections, mechanical parking in buildings/hotels and escalators.

Dry pendent sprinklers are designed for use in special applications such as cold weather environment. It can be used for both a dry and wet system. The design of the sprinkler prevents the accumulation of water condensation in the drop nipple which prevents damage from freezing. It is mainly used in tunnels, parking lots and other cold ambients.

In-rack Sprinklers are developed to operate in places with several levels in the same area. It is mostly used in spaces where water shielding is required such as rack storage facilities. The disc mounted above the heat responding element prevents malfunction by protecting the fuse from sprinkler waters from a higher level which may have been switched on earlier during a fire.

This is our selection of sprinklers:

1. Conventional sprinklers
2. Concealed sprinklers
3. Attic sprinklers
4. Extended coverage
5. Dry sprinklers
6. In-rack sprinklers for warehouses
7. Clean room sprinklers
8. Foam Nozzle

Compensators, check valves and water hammers

New in our assortment are the earthquake free couplings and shock dampers that can withstand movements of the pipe network up to 200 mm. We have FM certification up to a diameter 8”. Alternative sizes can be delivered on request.

For rooms with an explosion hazard we have explosion proof tubes that protect your data cables, electric cables, and fluids from explosion danger. These tubes are also fire resistant.

Water recoil that can occur with the abrupt starting or stopping of a water pump can be absorbed with a check valve or water hammer.

We have a wide range of solutions for non static applications in for example machine rooms. These are solutions like shock dampers, axial compensators, and bellows, that protect your pipeline network and couplings from vibrations and damage.

Valves and alarm valves

For new building projects we can provide a preconstructed assembled alarm valve and floor risers. We can provide these according to your product specifications, with or without check valve, manometer, test and drain valve, and flow switch. They can be configured to the left or to the right.

You not only save money by using one supplier, but you’ll also save a significant amount of time that you would otherwise spend on assembly. We can also supply alarm valves for wet pipe systems in frost free rooms or dry alarm valves for dry pipe systems used in unheated rooms. We also offer a deluge alarm valve in combination and a pre action alarm valve. All our products are FM certified.

We can also provide lose butterfly valves, check valves, check valves with grooved coupling of 2” to 12”, open gate OS&Y valves, NRS gate valves, and other valves like ball valves, ITC’s, and zone checks.

For your maintenance we can supply maintenance materials for the globe sprinkler products.

Tubes

Our tubes are strictly produced and treated according to the norm GB/T5135.20-2010. Both the inside and the outside are treated against corrosion and both sides contain a heat resistant plastic epoxy layer (RAL300). The epoxy layer remains undamaged when exposed to a temperature of 300 degrees celsius for 1 hour. The anti corrosion layer and the heat resistant epoxy layer make these tubes suited for water supply in fire extinguisher installations.

CPVC tubes and couplings

In light hazardous situations, one may apply Chlorinated Polyvinyl Chloride (CPVC) sprinkler systems. Both for standard sprinkler and concealed sprinklers. CPVC matches the required fire protection regulation and is a good alternative for metal sprinkler systems. CPVC has a longer expected lifetime of 50 years which is 10 years longer than metal. The interior of the products is smoother than metal which results in a better Hazen-Williams coefficient and lower friction losses. They are easy to install so installation will be fast and CPVC is cheaper than any other material.
