PVC Formulation:

  • The Plastics Pipe Institute (PPI) publishes the industry standard for PVC formulation for pressure pipe in its Technical Report #2 (TR-2)
  • Based on over 40 years of testing, PVC pressure pipe made to PPI TR-2 will have a Hydrostatic Design Basis (HDB) of 4000 psi - a basic requirement of PVC pressure pipe.
  • The UGSI formulation is the result of determining the right ingredients and the amounts that are optimal for fusion with the UGSI fusion process and in conformance to PPI-TR-2
  • UGSI's specific formulations are proprietary and patents are pending.
  • UGSI's proprietary formulations meet C900/C905 and NSF 61 requirements.

Fusion:

  • PVC fusion is performed on industry standard fusion equipment - which in some cases has been modified slightly
  • The fusion equipment must be in good mechanical, hydraulic, and electrical condition for use in Fusible C-900®, Fusible C-905® and FPVC® applications
  • All fusions are accomplished with a datalogger which records time and pressure for the duration of the fusion process. Initial heat plate temperature is also measured and recorded.
  • Each fusion joint takes approximately 1.5 to 2 minutes per diameter-inch to be completed or about the same amount of time as an HDPE fusion joint. Site conditions, weather, pipe handling, etc. can affect the length of time to complete a fusion joint.
  • All PVC fusion technicians are trained and qualified to the UGSI fusion process. Fusion qualifications are for specific pipe sizes and for a length of time, normally one year. Refresher training after each year is required based on level of experience.
  • Testing of the fusion joint has been done in accordance with ASTM standards.
  • Tensile-strength testing across butt-fused joint is done per ASTM D638.
  • Burst testing of fused sections is done per ASTM D1599.
  • Fusion joints completed following UGSI procedures with UGSI formulated PVC pipe achieve the strength of the parent PVC pipe.

Applications:

Applications for this technology cover every aspect of piping installations including both pressure and non-pressure situations in the water, sewer, electrical, industrial and telecommunications industries. Fusible C-900®, Fusible C-905® and FPVC® have been installed at over 5000 sites throughout the US, Canada, Mexico, the Caribbean and New Zealand.

  • Water Mains (AWWA C900, C905)
  • Gravity Sewer and Force Mains
  • Process Water
  • Water Reuse
  • Irrigation and Raw Water
  • Storm Drains
  • Electrical and Fiber Optic Conduit
  • Casings

Features & Benefits:

Fusible C-900®, Fusible C-905® and FPVC® pipes are often installed by cost saving trenchless methods including:

  • Horizontal directional drilling
  • Sliplining
  • Pipe bursting

Fusible C-900®, Fusible C-905® and FPVC® are competitive for traditional direct bury methods in situations where the lines require shoring, restrained joints and/or cathodic protection - all of which are costly, labor intensive and reduce daily production rates. Fusible C-900®, Fusible C-905® and FPVC® offer these advantages:

  • Elimination of nearly all gasketed joints
  • Restrained joints without external harnesses
  • Larger flow area for the same outside diameter than HDPE
  • Standard ductile iron and industrial pipe sizes
  • Simple connection and reconnection
  • Sizes range from 3" through 36" with larger sizes (42" and 48") to be available in the near future

Material and mechanical advantages of Fusible C-900®, Fusible C-905® and FPVC® include:

  • PVC is today's most widely utilized pipe material in the United States
  • Fusible PVC™ pipe provides a monolithic, fully restrained, gasket free, leak-free piping system
  • PVC has superior stiffness (modulus) compared to other plastic pipe which limits long term deformation under soil load
  • High tensile strength (ASTM D638) of the fused joint (up to 7000 psi) allows for higher safe pulling stresses and consequently longer installation pull-in lengths
  • Low wall thickness for given pressure requirement translates into highest flow per outer diameter (OD) dimension
  • Fusible PVC™ has a specific gravity of 1.40 - it will not float in a flooded trench
  • PVC material properties have low time dependencies - the properties do not change over time - no pull-in relaxation period for example
  • Standard waterworks fittings are used to tap, connect and change direction on Fusible PVC™ pipe systems - eliminating the use of expensive transition fittings or fused-on fittings
  • PVC resists hydrocarbon permeation better than other thermoplastic pipe systems (AWWA Research Foundation)
  • PVC is more resistant to water disinfectant induced oxidation than other thermoplastic pipe systems
  • PVC has been used for over 50 years - owner and contractor familiarity of the pipe is well established
