PE100-RC IN LARGE DIAMETER SEA OUTFALL APPLICATIONS

Author(s) : Mark Yu, Dongyu Fang, Peck Tze Kang, Amos Tay , Fan Liu 2018 Las-Vegas

Large diameter pipe was introduced in refineries and petrochemical plant, desalination plant and power plant for water intake and sea out fall in the past decade. PE100-RC material was selectedfor its excellent balance of superior bi-modal stress crack resistance and consistent high stiffness modulus. Under the...

PERFORMANCE EVALUATION OF COUNTER-ROTATING CONTINUOUS MIXER AND CO-ROTATING TWIN SCREW EXTRUDER FOR HIGH DENSITY POLYETHYLENE

Author(s) : Sayaka Yamada, Kazuhide Sekiyama, Shiori Watanabe, Kazuo Yamaguchi, Hideo Funahashi 2018 Las-Vegas

Performance evaluation method of plastic mixers for high density polyethylene by using flow simulation is presented in this study. First, Mixing experiments were performed to find the mixing performance of mixers. Then, flow simulations using our original software in the mixers were carried out to know the important...

PERFORMANCE OF LARGE MARINE HDPE PIPES DURING THE SUBMERSION AS BASED ON LABORATORY TESTING

Author(s) : Ilija Radeljic, Ingemar Björklund 2018 Las-Vegas

Installations of solid wall HDPE pipes are becoming more difficult and riskier with the increase in diameter (OD2000+ mm), length of strings (1000+ meters) and reduction in the wall thickness (SDR26-30). To gain a better understanding of the limits of the final pipe assembly prior to the sinking, a laboratory tests in...

PIPELINE REPLACEMENT IN LAS VEGAS

Author(s) : Roger Jordan, Ryan Benner, Greg Kodweis 2018 Las-Vegas

The Las Vegas Valley Water District (District) delivers water to approximately 1.4 million residents within the City of Las Vegas and unincorporated Clark County. The District maintains more than 4500 miles of water pipeline ranging from 4-inches to 102- inches in diameter, as well as another 2,000 miles of...

POLYEHTHYLENE/ALUMINUM/POLYEHTHYLENE COMPOSITE PIPE FOR FUEL GAS APPLICATION

Author(s) : Baiqian Li, Jun Wang, Lixian Zheng, Xiaoyi Peng, Lei Wang, Yu Cui, Guozhi Xu 2018 Las-Vegas

Polyethylene/Aluminum/Polyethylene (PAP) composite pipe has the advantages of corrosion resistance, limited joints and convenient installation. Nowadays PAP pipes are widely used in indoor gas conveyance. But a number of companies encounter difficulties in installing gas meter in users’ house as well as billing....

POLYETHYLENE PIPELINE PERFORMANCE AGAINST EARTHQUAKE

Author(s) : Hideki Omuro, Tomokazu Himono 2018 Las-Vegas

In Japan, polyethylene (PE) pipe have been used for a long time, but its usage is limited for water service (low density PE / PE 50) and gas service (medium density PE / PE 80). However, after Hyogoken Nanbu Earthquake in 1995, it started to sell PE pipes for water distribution applications, because no damage on PE...

POLYOLEFIN PIPES IN THE MIDDLE EAST- TODAY AND TOMORROW

Author(s) : Robert Lawrence, Mohana Murali 2018 Las-Vegas

The paper covers the growth of the polyethylene pipe sector in the Middle East from the 90s to the present. The initial slow uptake was related to ignorance of the material properties from the end users through to designers and installers. Recently the Middle East has become a world leader in the use of ever larger...

PREPARATION AND STUDYING OF THERMOPLASTIC CROSS-LINKED POLYETHYLENE

Author(s) : Cheng Zhi, Mingyuan Hu, Kaige Duan, Chaoxi Zhou, Dongming Yu 2018 Las-Vegas

The PE properties are obviously improved by crosslinking modified to TPEX, which can approach to that of PEX, while still remaining thermoplastic. It can be processed by the common forming method of thermoplastic; the products can be hot-melted and the scrap can be processed to be reused. The two-layer structure...

PREPARATION AND STUDYING OF TWO-LAYER OXYGEN BARRIER PLASTIC PIPE

Author(s) : Mingyuan Hu, Dongming Yu, Zhangcheng Chen, Cheng Zhi, Kaige Duan 2018 Las-Vegas

Studying in barrier property of TLCP/PO alloy and EVOH/PO alloy. Filtrating formulas with extruding alloy into pipes. Trying to coat alloy on pipes and co-extrude into two-layer oxygen barrier plastic pipe. The traditional Ethylene vinyl alcohol copolymer (EVOH) barrier plastic pipe used in internal closed-loop...

PRESERVING MARINE ENVIRONMENT FROM HYDROCARBONS CONTAMINATION WITH LEAK-FREE PE100 PIPES USED IN OFF-SHORE OIL WELLS

Author(s) : Farraj Tashman, Mohamed Ali Jaber, Sultan Al Kendi 2018 Las-Vegas

Analysis of subsea PE100 pipeline conveying oil produced water effluent with traces of hydrocarbons was done after 5 years of leak-tight continuous operation at boundary conditions showed that properties of PE100 pipes are intact when benchmarked with test results conducted on reference pipe sample kept for this...
