Chem Proline® & Chem Prolok™ Piping Systems Basic Design and Installation Considerations Thermofusion Properly trained installers are critical to overall system performance. Asahi/America recommends plastic pipe contractors maintain certifications according to DVS thermofusion guidelines. Asahi/America is proud to offer job site training according to DVS guidelines. Training should be conducted a maximum of 1 week prior to beginning of installation by authorized Asahi personnel. Socket Fusion Heater Inserts The illustration to the right shows socket fusion steps: • Melting the Pipe and...

Chem Proline® & Chem Prolok™ Piping Systems Basic Design and Installation Considerations Heater Butt Fusion Butt fusion thermally bonds pipe and components by heating the face of the components. Once elevated to the material specific melting temperatures the component faces are pressed against each other. Bench top welding tools are capable of welding up to the maximum size available in the piping system. Welding equipment up to 160mm (6”) can often be used in hard to reach areas like pipe rafters. Inital Melt Molten End Welding Equipment Miniplast 20-110mm (1/2” - 4”) Heat Soak Time...

Chem Proline® & Chem Prolok™ Piping Systems Basic Design and Installation Considerations Pressure Rating: The design stress is based on the hydrostatic design basis(HDB) of the material. S = (HDB) / F where F is a safety factor. HDB is determined from testing the material according to ASTM D 2837 to develop a stress regression curve of the material over time. By testing and extrapolating out to a certain time, the actual hoop stress of the material can be determined. Permissible operating pressure for Chem Proline® piping system is 150psi but must be reduced at elevated temperatures. The...

Chem Proline® & Chem Prolok™ Piping Systems Basic Design and Installation Considerations Change of Length Due to Thermal Expansion: Change in length due to thermal expansion must be considered if the temperatures during installation and operation are different. Plastic has the property of expanding under heat. L The calculation of the change in length of Chem Proline® pipes is based on the following formula: DL = change in length due to the temp. change [mm] a = linear expansion coefficient DT = difference in temperature L The length change results from the difference between the...

Chem Proline® & Chem Prolok™ Piping Systems Basic Design and Installation Considerations Anchors and Supports: Chem Proline® must be properly installed in order to provide worry free use. Support spacing is calculated by determining the material specific properties, ambient temperature, media temperature and specific gravity. The chart below shows recommended support spacing for Chem Proline®. It is also possible to continually support the system in a pipe tray and/or V-channel. Support Spacing (feet): Size Burial Considerations: The resin system used for Chem Proline® and Chem Prolok™ is...

Chem Proline® & Chem Prolok Piping Systems Basic Design and Installation Consideration Abrasion Resistance: In principle, thermoplastics are better suited for the conveying of slurry than available alternatives such as concrete pipe or steel. The Darmstadter method is a standard test procedure to determine the abrasion resistance of piping components. According to this method, a 3 foot length of pipe is cut in half to form a trough. The trough is tilted at a The chart below illustrates Chem Proline's superior abrasion resistant characteristics. ASAHI /AMERICA
