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
SAND AS INSULATION – REVISED
September 29th, 2014
ASHRAE 90.1-2013, Table 6.8.3A “Minimum Pipe Insulation Thickness Heating and Hot Water Systems” lists the required insulation conductivity for piping carrying hot water heating and domestic hot water systems. Some of the data from that table have been summarized below: Fluid Temp. (°F) Conductivity Pipe or Tube Size < 1 1 to < 1 ½ 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
Direct Burial of Aquatherm Piping
August 7th, 2014
201408D – AQTTB Date Issued: 7 August 2014 Aquatherm pipe is an excellent option for underground, direct-bury installations. The following are recommendations when using Aquatherm pipe in a direct-bury application. Trenching During trenching excavation ensure that the trench walls are stable under all working conditions. Provide sloped walls where appropriate and trench wall supports whenever Read More
ALLOWABLE LOADING OF BURIED AQUATHERM PIPE
July 14th, 2014
Buried piping systems experience static-loading due to the embedment material above them as well as live-loading due to moving or temporary objects, such as semi-trucks and trains, passing above them. For systems buried less than 50 ft underground a conservative method of calculating the static load acting on the system is to multiply the density Read More
Large Diameter Ball Valve Bolts
July 9th, 2014
201406D – AQTTB Date Issued: 9 July 2014 It has come to our attention that there is an error in the catalog on the bolt sizing for the large diameter Aquatherm ball valves.3 The catalog bolt sizing should read as follows: Part No. Dimension Bolt Sizes 0041602 3” – 90 mm M16 x 2.0 x Read More
4” FLANGE ADAPTERS
July 9th, 2014
In the past Aquatherm offered two different flange adapters for 4” inch pipe. The purpose of this technical bulletin is to help distinguish between the two products in order to help eliminate confusion and ease concerns when ordering. Aquatherm has since discontinued offering the No. 0115527 and it does not appear in the new 2014 Read More
AQUATHERM BENDING AND DEFLECTING
June 9th, 2014
In general Aquatherm does not recommend bending Aquatherm pipe as a means of making a change in direction or going around obstacles. However there are instances when the pipe is required to bend. When installing Aquatherm in a directional boring application or when encountering unexpected permanent obstacles in open trench applications, the pipe may need Read More
AQUATHERM BRASS VALVES
June 9th, 2014
The brass-bodied valves offered in the Aquatherm 2014 catalog are not intended for use in potable water systems as they do not meet the new zero-lead requirements which went into effect January 1, 2014. These valves include the brass/PP-R ball valve, the screw–down stop globe valves, the draining branch valve, the chrome plated concealed valves, Read More
