Profipress makes short work of hotel alterations

Prestige hotels are always busy and open for business 24/7 so any alterations or changes to essential services have to be accomplished with the minimum disruption to the hotel’s clientele.

When work was required on the large incoming water main and hot and cold water distribution pipework at a prestigious Cape Town hotel and spa, specialists Grinstead Plumbing were called in to tackle the job.

“Through our a long association with the hotel, we understand the necessity to ensure that any alterations to the hot or cold water services shouldn’t be an inconvenience to the hotel’s guests” says Stanley Frenchman, Grinstead Plumbing’s contracts manager.

In addition to hot and cold water services to the hotel’s more than 200 rooms, kitchen services, fitness centre, spa and a swimming pool all rely on these essential services.

“The work involved cutting-in to the hotel’s 110mm diameter water services pipework” explained Stanley. “A water meter had to be installed on the incoming main from the street, two isolation valves for hot and cold services were needed from the boiler room and the hotel required a water meter to be installed on the hot water line to provide details of guest water consumption” said Stanley.

All the reticulation pipework in the hotel is copper, and traditional methods of soldering pipe fittings have distinct disadvantages in that there can be a fire hazard when using an open flame, especially in restricted spaces and all the water has to be drained from the system to ensure a perfect leak free joint.

A better way was provided by Viega’s Profipress copper pipe range for commercial, residential and industrial applications, which provides a complete solution for wet and dry services in new or renovation installations and in repair situations.

Pipe materials, dimensions and installation are the deciding factors for the preservation of hygienic water quality and the precision engineering found in the Profipress copper system achieves permanent professional results through their patented system of press connectors while offering a reduction of installation time of between 30 – 50% compared to soldering.

“The Profipress system with slip collar fittings worked a treat at this installation as the work was completed within a few hours at night with no inconvenience to guests, and we didn’t have to drain the whole system or shut down the boiler which saved a huge amount of time and effort, not to mention the waste of thousands of litres of water, some of which would require to be heated…” explained Stanley.

More than 800 individual components make up the range of fittings and specialised control devices made of copper and gunmetal in sizes 12 to 110 mm, through the pressure range from 2.2 kPa to 1600 kPa for virtually any situation.

Leak proof, clever design

Viega press technology - which is also available for steel pipes, is guaranteed leak-proof due to the fitting’s unique SC Contur safety factor which immediately reveals leakage under test of any un-pressed fittings. Remedial work can be accomplished without time consuming dismantling or pipework modification, even with a system under pressure by simply pressing the leaking connection with Viega’s special pressing tools The innovative design applies a double press connection in one pass – before and after the bead, providing a long lasting, permanent and torsion proof connection. Its high-quality sealing element is optimally protected against damage due to the cylindrical pipe design.

Quick, easy and permanent

The fast processing rate of the Viega press connectors involves just three processing steps – cutting the pipe to length; installing the press connector and verifying the insertion depth – then pressing in one pass. No calibration, as in the case of other piping systems, is necessary which saves as much as 30 to 50 percent in labour time compared to soldering.

A single compact press tool

The pressing operations are executed with the matching press tools and jaws. As well as mains powered press tools, there are also battery powered tools which provide a high degree of flexibility. Their extremely compact design means they can also be used to work in difficult-to-access locations, such as in installation ducts. 180° swivelling jointed press jaw sets provide even greater flexibility where required.

Fire hazard eliminated

Another reason why press connecting technology has had such success internationally is its inherent safety, especially compared to soldering. As pressing involves no open flame, and so poses no fire hazard, no fire safety measures are needed. Consequently, press-connected pipes can often even be installed in hazardous and/or explosive industrial environments without interrupting production operations.

Caters for all wet and dry building services

The Profipress system of 800 different components caters for any type of wet or dry building service including:

  • Water-Flushed Drinking Water Connections
  • Cold Water Distribution
  • Hot water Connections
  • Heating systems – radiator or underfloor
  • Gas – tamper-proof and fireproof
  • Special applications – oil, fuel and solar energy
  • Industrial applications – handling a wide range of liquid and gas media.

 

Reliable interfaces

All types of interface fitting connections are catered for including noise insulated wall plates, wall ducts, pre-wall systems and flexible piping systems such as the Viega Fonterra system of water based underfloor heating.

Materials, production and quality control

Viega only uses materials suitable for use with drinking water such as stainless steel, copper and copper alloys. All organic materials for seals and pipes regularly undergo the relevant chemical and microbiological tests.

Innovative Product Design

Viega press connectors made of copper, gunmetal and stainless steel cause much less flow resistance than other types of plastic or press brass connectors that are available on the market. When using plastic connectors, a solid core is required for all subsequent cavities, which is then extracted again after production. Brass connectors are simply bored at a right angle – quite the opposite of the flow-enhancing water flow conditions from Viega.
