In January 2013, a major pharmaceutical manufacturer located in the Northeast faced a domestic water piping retrofit at one of its biopharmaceutical research centers. DECCO, a Brookline, NH-based mechanical contractor that has extensive experience in the mechanical aspects of “bio-pharm” applications, was called upon as a project engineer to come up with a solution. In Read More

TECHNICAL BULLETIN: 201212B-AQTTB Date issued: 27 Dec. 2012 Recently Aquatherm announced that Aquatherm Advanced (Reflectix) was being discontinued. Aquatherm is getting out of the insulation business. In the meantime, it is recognized that an alternative to Aquathem Advanced needs to be provided. While Aquatherm does not promote one brand of insulation over another, the accompanying Read More

Due to gravity and the physics of extrusion, larger pipes tend to be slightly thicker on the bottom than they are on the top. However, the top will always be at least as thick as the production SDR, so there is no concern over pressure and temperature ratings. This difference is not enough to cause Read More

201211A – AQTTB Date Issued: 6 December 2012 The need for thermal expansion joints in piping systems arises from the tendency of the pipe to expand or contract due to changes in temperature of the pipe material. This expansion can either be directed to a specific location (i.e. expansion joint) by anchoring the pipe away Read More

Aquatherm pipe has a high thermal resistance value, giving a level of natural insulation to the pipe. With this high level of thermal resistance many have supposed that Aquatherm pipe can be installed in many instances without thermal insulation. While this may indeed be true in some instances, most of the time and according to Read More

201209A – AQTTB Date Issued: 13 September 2012 New Construction Pipes typically are found in groups of various sizes running side by side. This can ease installation by allowing multiple pipes to rest on a single trapeze pipe support. But every differing pipe size has different support spacing, complicating this approach. Aquatherm has developed a Read More

201208B – AQTTB Date Issued: 15 August 2012 Many state and local codes require the installation of water hammer arrestors at locations of quick closing valves. This is done to protect metallic pipe from the high-pressure shocks that can occur when these valves are actuated. The pressure surge, and its effect on the pipe, is Read More

201208A – AQTTB Date Issued: 15 August 2012 Condensation on any surface depends on the temperature of the surface, the ambient air temperature and the ambient relative humidity level. The relative humidity level is the amount of moisture or water vapor that is contained in the air at a certain temperature compared to the maximum Read More
