Plastics pipe industry resource launches new website

The Hydrostatic Stress Board (HSB), an independent, technical-based group of voluntary industry experts, operating under the auspices of the Plastics Pipe Institute, Inc (PPI), has reconstructed and expanded its website section to speed up the listing request process, and to highlight the long-standing history of its board. Added content includes downloadable forms and templates to submit requests for compounds and composite plastic pipes (PPI TR-4) as well as ingredients and PVC resins used for vinyl pipe (PPI TR-2) for inclusion in the HSB listing programme. Other new documents include step-by- step instructions about the submission process, reports of relevance about policies in PPI’s Technical Report (TR) PPI TR-2 and PPI TR-3, which are two key documents detailing listing requirements, an online HSB enquiry form, and an announcements page to keep listing owners up to date on the board’s activities and developments. “The HSB continues to add more services to the industry,” stated Tony Radoszewski, president of PPI.

of extensive tools in this enhanced web section facilitates understanding about the programme’s listing process and how to participate – a programme providing a prominent level of qualification and affirmation about the uses of plastics in pipe systems.” The HSB comprises engineers, chemists, scientists and others with expertise in thermoplastics, ingredients, processing and long-term strength testing. The board is chaired by PPI’s technical director, Sarah Patterson, who commented, “HSB policies define procedures for determining the long-term strength of plastic pipe compounds, and for converting this strength into an allowable design stress which, in turn, is used to determine the pressure rating of the plastic or composite pipe.” Listing in the HSB programme does not require PPI membership, as it is a service to the entire plastics industry, hosted and managed by PPI.

“For nearly six decades, the HSB has contributed to the confidence level of plastic pipe and materials used in numerous applications including gas, municipal water, wastewater, sewer and industrial water systems. The provision

HSB policies define procedures for determining the long-term hydrostatic strength of plastic piping materials such as PEX pipe used for hot and cold potable water systems
