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
OVALITY IN MACHINE ASSISTED FUSIONS
August 29th, 2013
When using any fusion assistance machine, avoid clamping the fitting in a way that will cause the opening to form an oval shape. The welding heads are designed to operate under very specific tolerances, and compressing the end of the fitting can prevent proper contact, and thus proper fusion. Some bench top machines are more Read More
AQUATHERM AND SOLAR
August 29th, 2013
Aquatherm piping is an excellent choice for use with most solar heating applications. There are, however, a few precautions that need to be observed when using Aquatherm in the solar piping system. The most significant use of solar heating has been for swimming pool, domestic hot water, and space heating. Solar collectors are classified according Read More
Aquatherm Temperature Spikes and Boiler Malfunctions
August 29th, 2013
201308E – AQTTB Date Issued: 28 August 2013 The temperature/pressure ratings in the Aquatherm literature are based on averages over the life of the system. For example, the rating at 180°F would be applicable for a system with a set point of 180°F, with the expectation that the true temperature of the system would fluctuate Read More
Aquatherm Valve Applications
April 23rd, 2013
201304A – AQTTB Date Issued: 18 April 2013 Aquatherm offers a variety of valves in our catalog. These valves range in offering between the screw-down stop globe valve, concealed valves, inclined globe valves and ball valves. This document is an attempt to identify the valve offerings and their different applications. Globe Valves Globe valves are Read More
