Fire Sprinkler Systems with Anti-MIC Coated Metal Pipe
CPVC piping has been successfully used in combination with copper or steel piping for many years when proper attention is given to cutting oils, thread sealants and other potentially incompatible materials that can cause Environmental Stress Cracking (ESC) in CPVC. However, certain Anti-Bacterial Corrosion coatings designed to prevent Microbiological Influenced Corrosion (MIC) that are applied as a lining to metal pipe are at the center of a major ESC problem concerning combination of CPVC with Metal fire sprinkler systems.
When you're installing or specifying CPVC fire sprinkler piping products, there's no substitute for quality. That's why customers choose GF Harvel. With our extensive experience and proven reliability, there's no question that you're getting the durability and quality you demand in a sprinkler system.

TUBING & FITTING RELATED
Hose Tube & Fitting - BACK TO BASICS
It is extremely important that the fitting and hose or tubing be properly matched in size and type. The insert should always be slightly larger than the tubing to create a slight expansion of the tube and provide a good consistent seal.
If a clamp or ferrule is used to compress the hose, caution must be used to prevent over-crimping the ferrule or over-tightening the clamp. More pressure does not necessarily improve fitting retention.
The Best tubing material for demanding fluid handling
Specifying the best tubing material for demanding fluid handling applications is critical. Seek a partner that is more than a component supplier, but one capable and willing to collaborate with you to develop optimum solutions.
ZEUS' Advanced Manufacturing Processes for PTFE - Polytetrafluoroethylene
Originally discovered in the 1930's by DuPont® scientist Dr. Roy Plunkett, PTFE was first used in the top secret Manhattan Project during WWII. DuPont® commercialized PTFE under the tradename Teflon® in the late 1940's.
Extrudable grades of PTFE were commercialized later and in 1966 ZEUS was founded and began development of advanced manufacturing processes for PTFE - Polytetrafluoroethylene.
The general properties of PTFE are typical of other semi-crystalline high performance thermoplastics:
Working Temperature Range -454° F.To 500° F.
Low coefficient of friction
Outstanding temperature stability
Outstanding electrical properties
Outstanding chemical resistance
Outstanding weathering and UV resistance (although PTFE can be degraded by gamma radiation dosages above 70 Mrad)
Good toughness but generally low mechanical strength
Water hammer refers to fluctuations caused by a sudden increase or decrease in flow velocity. These pressure fluctuations can be severe enough to rupture a water main. Potential water hammer problems should be considered when pipeline design is evaluated, and a thorough surge analysis should be undertaken, in many instances, to avoid costly malfunctions in a distribution system. Every major system design change or operation change—such as the demand for higher flow rates—should include consideration of potential water hammer problems. This phenomenon and its significance to both the design and operation of water systems is not widely understood, as evidenced by the number and frequency of failures caused by water hammer.

CROSSLINKED PE TANKS WITH LINEAR PE LINERS A BAD IDEA?
Approximately 30 years ago, a technique was developed within the rotational molding process that enabled a Low Density Linear Polyethylene (LLDPE) and/or Medium Density Linear (MDPE) Liner (layer) to be formed within a crosslinked Polyethylene (XLPE) Tank.
Initially the additional layer of LLDPE material was added to reduce cost using a cheaper resin to build wall thickness. In the late 1980’s, early 1990’s it was also done in an attempt to create an FDA line of tanks which failed to comply with FDA requirements. Then the process was used to actually improve the chemical resistance of the XLPE tank in certain oxidizing chemical applications. There were limited tank material construction options at the time the dual layered tank was developed, and the LLDPE and MDPE resins did not yet have the strength characteristics to handle the rigors of bulk liquid storage without additional support, which is why the two resins were utilized together in an attempt to solve a chemical storage dilemma.
