The local utility or engineer may need to modify this model specification to adapt the document to local conditions, operations, and practices.”

“This model specification was originally prepared and now has been updated by MAB members and associates as a service to the water industry,” explained Camille George Rubeiz, co-chair, Municipal Advisory Board and senior director of engineering, Municipal and Industrial Division at PPI. “It is intended as a guide for

The MAB-3 model specifications guide for PE 4710 buried potable water service, distribution and transmission pipes and fittings has been updated, and is now available. The document covers system design parameters, quality control, pressure classes, pipe and fittings, training and

inspection, joining methods such as butt fusion, saddle fusion, socket fusion, electrofusion and mechanical, plus open cut and trenchless installation for water services ( 3 / 4 " to 3" per AWWA C901), and for water distribution and transmission (4" to 65" per AWWA C906). Additionally, MAB-3 provides an appendix with a list of references from ASTM, AWWA, MAB, NSF and PPI.

SABIC expands water management portfolio with new NORYL ™ resin

“Our internal testing has demonstrated that the new NORYL WM330G resin provides a wider processing window, which makes the material a candidate for more-complex part designs where the hot-spot phenomenon could create a long-term performance issue,” said Iassen Popov, segment leader, NORYL Global Water Management, SABIC’s Specialties business. The new NORYL grade, available globally, is being produced at the company’s facility in Bergen op Zoom, Netherlands. It complies with the NSF/ ANSI Standard 61, Germany’s KTW/ W270 certification, France’s Attestation De Conformité Sanitaire (ACS) and the UK’s Water Regulations Advisory Scheme (WRAS), which addresses certification for cold, warm and hot water applications.

this enhanced grade of NORYL resin to give our customers a greater selection of high-performing thermoplastic technologies that address some of their most demanding application requirements. We also guide and support customers throughout design, part performance simulation and testing, tooling and processing to help ensure they achieve the best results from whichever NORYL water management grade they choose.” NORYL WM330G resin delivers higher burst pressure, fluctuating pressure and creep rupture performance to meet more aggressive qualification testing and also enables robust injection molding with minimal effects on mechanical properties. NORYL WM330G resin can also help control costs compared to other high-performance glass-filled materials as it has lower specific gravity, which may yield more parts per unit of weight.

Petrochemicals manufacturer Sabic has announced the launch of NORYL™ WM330G resin, the latest addition to its portfolio of high-performance thermoplastics for water management applications. The new product is the first in a family of materials featuring proprietary impact-resistant technology for improved fluctuating pressure performance compared to legacy materials. “As global water regulations become increasingly strict and application requirements expand, SABIC is help- ing the water management industry stay ahead of changes in the mar- ket, especially with regards to ongoing compliance, performance and sustain- ability challenges,” said William Wan, global business director, NORYL Resins, SABIC’s specialties business. “To do this, we are investing in the development of new materials such as
