Experimental Verification
Key Raw Materials
At Shandong Donghong Pipe Industry Co., Ltd., the binder resin is the cornerstone of our Engineering Support High Density Polyethylene Pipe, ensuring impeccable stress transfer during high-pressure applications. Leveraging our specialized raw material design and development platform, we meticulously refine the binder resin to achieve unparalleled performance. This advanced composite material seamlessly integrates with our cutting-edge processes and state-of-the-art equipment, exemplifying our unwavering commitment to quality and innovation.
Plating is essential to our product's durability, providing outstanding corrosion resistance and significantly enhancing the shear strength between steel wire and bonding resin. Comprehensive data testing has shown that the choice of plating material dramatically impacts shear strength. Tin bronze plating outperforms with an impressive average shear strength of 20.69MPa, compared to 11.42MPa for brass. Consequently, our Reliable Srcp Tube for Water Transportation utilizes tin bronze-plated steel wire, ensuring it excels as the premier substrate for pressure-bearing applications.
