EFFECT OF INSUFFICIENT HOMOGENIZATION DURING THE EXTRUSION OF POLYETHYLENE PIPES ON BUTT FUSION JOINT INTEGRITY
Mike Troughton, Amir Khamsehnezhad, Changyi Yu # 2021 Amsterdam When butt fusion welding polyethylene (PE) pipes in the field, it is often specified that the pipes must undergo fusibility testing in all combinations of suppliers, diameters and thicknesses before being fused in production. This is a very onerous and expensive task, but must be carried […]

DESIGN OF A DISTRIBUTED STRAIN MONITORING SYSTEM FOR HDPE WATER PIPELINES CROSSING AN EARTHQUAKE FAULT
Peter Hubbard, Linqing Luo, Andrew Yeskoo, Kenichi Soga, Krista (Moita) Araica, Gus Cicala, Marshall McLeod # 2021 Amsterdam Seismically active faults pose a risk to buried water pipelines that can be complicated to quantify. Fault type, slip rate, pipeline geometry, and soil conditions all factor into a complex soil-pipeline interaction. For critical pipelines that cross […]

UTILIZATION OF HDPE RECYCLED MATERIALS IN SANITARY SEWER APPLICATIONS
John M. Kurdziel # 2021 Amsterdam The use of recycled plastics in high density corrugated polyethylene pipe for storm sewers, highway culverts and general land drainage applications has now been widely accepted by municipalities and transportation agencies. This acceptance has made it possible to convert what was once considered a single use plastic product to a long-term […]

A NEW GENERATION OF HIGH PERFORMANCE BIAXIALLY ORIENTED POLYETHYLENE AND POLYPROPYLENE PRESSURE PIPES
Taraiya, P. Degenhart, M. Soliman, M. Boerakker, R. Handstanger, R. Kleppinger # 2021 Amsterdam Since the introduction of polyolefins for pressure pipes, continuous improvements have been made to meet ever-higher demands on their performance and to expand their application window beyond their original scope, mostly based on new resin formulations. Today, we also continue to […]

AN EVIDENTIAL APPROACH TO USE OF POLYETHYLENE PIPE FOR HYDROGEN FUEL GASES
Derek Muckle # 2021 Amsterdam A technical program has been undertaken to provide evidence on the suitability of polyethylene pipe and fitting systems for the distribution of hydrogen fuel gas. The underlying principle has been to evaluate material in the form of a pipe and to consider the performance of the pipe and of the welded jointing […]

WHY CHOOSE SHUANGLIN HDPE SPIRAL PIPE #part 4
HIGH CHEMICAL RESITANCE HDPE high-density polyethylene is one of the most resistant materials to the majority of chemical compounds that appear in pipes, including H2SO4, HCL, HNO3, H3PO4, SH2, which is the most dangerous element in sewer pipes. Due to this, HDPE Spiral pipes guarantee their durability without the need for internal and / or […]

WHY CHOOSE SHUANGLIN HDPE SPIRAL PIPE #part 3
INTERNAL ROUGHNESS HDPE has the lowest Manning coefficient (internal roughness) compared to other materials on the market. HDPE manning coefficient is 0,010 smoothess than maning coefficient is 0,014. Therefore, under the same hydraulic design conditions (section, slope) with traditional technology, HDPE high-density polyethylene pipes have greater hydraulic capacity. When comparing HDPE pipes with Concrete pipes, it […]

WHY CHOOSE SHUANGLIN HDPE SPIRAL PIPE #part 2
PROFILE RIGIDITY SPIRAL high-density polyethylene pipes can be manufactured with the necessary rigidity, assigning different profiles depending on the different load conditions that the conduction will have to face along its route. IRAM 13414 Standard establishes that the annular rigidity of HDPE high-density polyethylene pipes must be at least SN2. When this rigidity is not sufficient, […]
