between Borouge and JPIS, which facilitates exporting our products to local and global part- ners,” said Khalfan AlMuhairi, senior vice president for Middle East and Africa exports at Borouge.


Test case Testing specialist CEIS can now provide a suite of tests to assess the performance of PE100RC – which has high resistance to slow crack growth. Revisions to two sets of UNE-EN standards allows the material to be used in applications including transport of gaseous fuels and pressur- ised water supply and sewage. CEIS has reached an agreement with the


Polymer Technology Laboratory (Latep) at King Juan Carlos University (URCJ) to provide testing of PE100RC materials. It will provide the complete test package to organisations – including manufac- turers and certification bodies – for conformity assessment of water and gaseous fuel supply systems made with PE100RC. It can now provide four tests: the Strain Harden-


ing Test (SHT); the Cracked Round Bar Test (CRBT); the Accelerated Full Notch Creep Test (AFNCT); and the Accelerated Notch Pipe Test (ANPT). SHT is carried out at 80°C to determine the


gradient of the strain graph compared to the time at the final stage of hardening before the sample breaks. CRBT is a cyclic strength test under a constant load conducted on a cylindrical sample (Ø=14mm) notched in the middle to start a quick fracture. The sample must withstand a minimum number of cycles (1.5 x 106) before breaking. The other tests – AFNCT and ANPT – were


previously included in the earlier revisions, but have since been modified for the high perfor- mance of PE100RC.


New ASTM standard ASTM has issued an updated standard for the use of HDPE pipe in horizontal directional drilling (HDD) projects. ASTM F1962-22, Standard Guide for Use of Maxi-Horizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit Under Obstacles, Including River Crossings, was revised and updated in December 2022 by an ASTM subcommittee. It includes pipe made with PE4710 compounds. In addition to ASTM, ASME and CSA standards, PE4710 has also been incorporated in AWWA (C901, C906, M55), FM 1613 and others. The pipe is used in force main, potable water and other projects. According to the Plastics Pipe Institute (PPI), PE4710 is the highest performance classification of

HDPE piping material for water applications. “PE4710 compounds offer utilities and design-


ers a greater level of performance,” said Camille George Rubeiz, senior director of engineering for PPI’s municipal and industrial division. “This means using HDPE with increased flow capacities plus increased resistance to surge pressure, fatigue and slow crack growth.” The new standard focuses on maxi-horizontal


directional drilling (maxi-HDD) that is typically used for longer distances and larger diameter pipes common in major river crossings. Rubeiz cited several recent applications, including one in Atlantic City where a 32in diam- eter PE4710 pipe ran for 1,500 feet – 80 feet below the Beach Thorofare waterway. Here, the critical force main line project was performed with a drilling rig that had a pulling force capacity of 250,000 pounds and a torque capacity of 40,000 ft-lbs.


In another, 4,000 feet of 20in HDPE pipe was embedded 60 feet below Florida’s Biscayne Bay to deliver potable water, replacing a 25-year-old leaking cast iron transmission line. “We encourage the use of F1962 – the only


ASTM Standard for HDD,” said Rubeiz. “This – cou- pled with Pipeline Analysis & Calculation Environ- ment and PPI-BoreAid free software programs – will provide the information for planning the design.”
