May 19th, 2014
201405B – AQTTB Date Issued: 20 May 2014 Aquatherm piping works great in conjunction with flanges with gaskets and butterfly valves in the piping system. Flanges and Butterfly Valve Installation Guidelines2 For a successful butterfly valve installation in Aquatherm piping the following procedures should be observed: Dry-fit the connecting pipe flange adapters and the valve Read More
AQUATHERM BUTT FUSION 4” PIPE
May 14th, 2014
Aquatherm has recently introduced the 4-in. (125 mm) Blue Pipe® SDR 17.6 faser-composite pipe available for purchase. This product line has been available in 6- to 24-in. diameter sizes for two years – and it still is. However, Aquatherm identified a customer demand for 4-in. Blue Pipe SDR 17.6 to allow for more cost effective Read More
AQUATHERM AND HIGH RISE CONSTRUCTION
April 29th, 2014
One of the eternal truths of this life is that water is heavier than air. It weight 62.4 lbs per cubic foot at 68°F. This mass requires a pressure of 0.433 pounds per square inch to lift water one foot. To put it another way, one psi will raise water 2.31 feet. These facts are Read More
LARGE DIAMETER BALL VALVE CLARIFICATIONS
March 6th, 2014
This bulletin is being issued to clarify the bolt connections and sealing of Aquatherm large diameter ball valves (part #’s 41602 – 41607). As can be seen on the face of the valve, there is an area where it appears a large O-ring can be inserted to help seal the valve connection to the piping Read More
Aquatherm Flow Velocities
February 28th, 2014
201401A – AQTTB Date Issued: 10 February 2014 One of the great selling points of Aquatherm is the pipe’s ability to be used at higher flow velocities than copper or steel. Typically, the model plumbing codes (UPC, IPC, NSPC, NPC) require design flow rates for non-metallic pipes to not exceed 8 ft./sec. (2.44 m/sec.). This Read More
NEW AQUATHERM FLOW SWITCH WELL
February 28th, 2014
To aid in mounting flow switches and other sensors onto Aquatherm pipe, Aquatherm has developed a new fusion outlet fitting to accommodate the larger paddle and/or sensor dimensions. The new fusion outlet configuration provides for a larger internal diameter, and shorter overall length. This allows flow switches with wider paddles or sensors with shorter elements, Read More
BUTT-FUSING OF DISSIMILAR SDRS
December 11th, 2013
From time to time there arises a need to butt fuse pipe of dissimilar SDR’s. For example many of our 6-inch molded fittings are made in SDR 7.4. In order to butt fuse the fitting to SDR 11 pipe the butt fusion heating times and pressures need to be adjusted to accommodate the difference in Read More
Aquatherm UV Protection
November 18th, 2013
201311A – AQTTB Date Issued: 18 November 2013 Prolonged exposure to UV radiation will discolor bare PP-R or RP (RCT) pipe and could weaken the polymer over time. In order to prevent this damage, suitable measures must be taken. As stated in the Aquatherm catalog, the ideal solution for installing PP-R or RP (RCT) in Read More
IDENTIFYING LEAD FREE VS. ZERO LEAD BRASS FITTINGS
August 29th, 2013
Aquatherm produces two types of metal transition fittings. Stainless steel transition fittings. Brass transition fittings. The brass fittings are broken down into two different types. Lead-free type. Zero-lead type (meeting the revised Safe Drinking Water Act requirements of less than 0.25% lead which goes into effect in Jan-2014). This paper will focus on the differences Read More
Oxygen Permeation and Aquatherm Pipe
August 29th, 2013
201308B – AQTTB Date Issued: 28 August 2013 There have been several articles published on the issue of oxygen permeation through plastic piping and the history regarding the testing and requirements established in Europe. First, it should be noted that the intent of the permeation testing and barrier on plastic pipe was to reduce the Read More
