AQUATHERM TECHINCAL ANNOUNCEMENT: RED-WHITE VALVES AND AQUATHERM
June 18th, 2015
Polypropylene ball valve with brass internal components, PP body and sockets Model 500AB, ½-2 inch This valve line has been introduced in North America recently, raising numerous questions regarding the use of these valves with Aquatherm piping. The following should be considered when discussing these valves: According to the manufacturer’s website, the valves are listed Read More
AQUATHERM THREADED ADAPTER FITTINGS
April 1st, 2015
Aquatherm offers several brass and stainless steel threaded transition fittings. When installing these fittings with other metal fittings, pipe or other threaded component a couple of items need to be observed. When making a threaded connection using an Aquatherm threaded adapter fitting (FPT) and metal threaded pipe or other component, the threaded component or pipe Read More
Heat Tracing Aquatherm Pipe
March 30th, 2015
201503A – AQTTB Date Issued: 2 March 2015 Aquatherm PP-R piping systems, Green Pipe, Green Pipe MF Faser, and Blue Pipe MF Faser are freeze tolerant meaning that they may experience inadvertent freeze/thaw cycles without sustaining damage to the pipe. However, the pipe should not be placed in an application where the potential for frequent Read More
EQUIVALENT LENGTH OF FITTINGS
March 3rd, 2015
The flow rates, friction loss data and velocities for a few given flow rates are shown in the catalog. This data are the result of calculations made with the Hazen-Williams formula which is also given in the catalog. The data shows the results of the calculations showing the friction loss of the pipe in feet Read More
FUSION OF AQUATHERM PIPE IN WEATHER EXTREMES
January 9th, 2015
COLD WEATHER HANDLING Aquatherm pipes have reduced impact resistance in sub-freezing conditions. It is imperative, therefore that the pipe be handled carefully when the weather get cold. Avoid dropping, handling the pipe roughly or stepping on the pipe. Avoid unnecessary impacts Use caution when cutting the pipe in cold weather conditions. Don’t use power cutters on the Read More
HIGH PURITY WATER SYSTEMS
December 9th, 2014
2011412A – AQTTB Date Issued: 9 December 2014 High Purity water has become an integral part of our lives today. It is an essential ingredient in hundreds of applications including medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes and even the final rinse at the carwash. Practically all water supplies have some dissolved impurities Read More
AQUATHERM AND BUOYANCY
November 5th, 2014
When it comes to aquatic applications, there are many advantages to using Aquatherm pipe rather than metallic piping. One of the most significant advantages is that Aquatherm pipe is corrosion resistant making it an ideal material to be used in harsh, underwater environments. Other advantages include the leak-free joints, made possible by the heat fusion Read More
AQUATHERM RED PIPE POLYPROPYLENE SPRINKLER PIPING
August 28th, 2014
The actual code requirements may vary somewhat with jurisdiction, but most codes refer to NFPA 13 – Installation of Fire Sprinkler Systems for requirements on the use of plastic fire sprinkler piping. Within NFPA 13, Table 6.3.1.1 provides a list of materials and standards for steel and copper pipe to be used in aboveground installations. Read More
STATIC ELECTRICITY
August 7th, 2014
Static electricity is caused by the contact and separation of two materials, one of which has a high electrical resistance. The difference in resistance causes an imbalance of electrons with one of the materials having a positive charge and the other material having a negative charge. When the two materials come into close proximity you Read More
