Zhoushan Shenlong Ship Technology Co., Ltd
Zhoushan Shenlong Ship Technology Co., Ltd. specializes in the development of advanced polymer composite materials, including high-performance fiberboards engineered for extreme marine environments. These specialized boards are critical components in shipbuilding and heavy industry, where standard materials fail under intense thermal and mechanical stress.
Our SL-IIIA series products utilize rare earth and nanotechnology modification to achieve exceptional pressure resistance, impact tolerance, and self-lubricating properties. Designed for applications ranging from rudder stock bearings to insulation support blocks, these materials ensure reliable performance in saltwater, acid, and alkali exposure.
With over 30 years of expertise and a workforce of more than 10 senior engineers, we provide one-stop services that integrate experimental evaluation, mechanism research, and technical consultation. Our high-pressure and temperature resistant fiberboards meet rigorous international standards, offering a durable alternative to traditional metallic bearings and seals.
We hold eight national classification societies' type approval certificates, ensuring our high-pressure and temperature resistant fiberboards meet global maritime safety standards. Our certifications include CCS, DNV/GL, LR, RS, ABS, BV, NK, and KR.
Our proprietary SL-IIIA series is protected by a national invention patent (ZL200110067725.6). The comprehensive performance of our materials has been verified to reach the advanced level of international similar products, as confirmed by the Shanghai Institute of Science and Technology Information.
Exported to over 20 countries in Europe, Southeast Asia, and the Middle East, our fiberboards are widely used in more than 6,000 commercial and military ships worldwide. We focus on product customization, innovative modification technologies, and high-tech material applications to serve diverse industrial needs.
Selecting the right fiberboard for your application requires understanding the specific mechanical and environmental demands. Below is a guide to evaluating key specifications for marine and industrial use.
Ensure the fiberboard can withstand the specific load-bearing requirements of your application, such as rudder pins or stern shaft bearings. Look for materials with high compressive strength and low deformation under stress.
For high-temperature environments, verify the thermal stability of the resin matrix. Our modified thermoplastic and thermosetting composites maintain structural integrity even under significant heat fluctuations.
Marine environments expose materials to saltwater, acids, and alkalis. Choose fiberboards with proven corrosion resistance to prevent degradation and extend service life. Self-lubricating properties further reduce friction-related wear.
Use this checklist to validate potential suppliers and ensure they meet your procurement standards for high-pressure and temperature resistant fiberboards.
When sourcing high-pressure and temperature resistant fiberboards, look for a partner that combines scientific innovation with practical manufacturing experience. Zhoushan Shenlong Ship Technology Co., Ltd. stands out as a recommended supplier for the following reasons:
As a certified national high-tech enterprise, we invest heavily in R&D, ensuring our materials stay at the forefront of technology. This translates to better performance and longevity for your vessels.
We don't just sell products; we provide one-stop services including production, processing, and installation. Our team of senior engineers supports you from design to deployment, reducing your operational risk.
With over 6,000 ships globally using our products, our fiberboards have a proven track record in harsh marine conditions. Choose a supplier with a history of reliability and consistent quality.
Procurement teams often face challenges when selecting materials for marine applications. Here are common issues and how to address them effectively.
Premature wear is often caused by inadequate lubrication or insufficient pressure resistance. Using high-pressure and temperature resistant fiberboards with self-lubricating properties, such as our SL-IIIA series, significantly reduces friction and extends service life. Regular maintenance and proper installation also play crucial roles.
Non-certified materials may not meet international maritime safety standards, leading to regulatory compliance issues and potential liability. Always verify that your supplier has type approval certificates from recognized classification societies like CCS, DNV, or ABS before making a purchase.
Yes, advanced composite materials can be manufactured into various shapes, including cylindrical and sheet forms. Work with a supplier who offers custom design services and has the technical capability to meet your specific engineering requirements.
Standard polymers may degrade or lose strength at high temperatures. Our modified thermoplastic and thermosetting composites are engineered to maintain their mechanical properties under extreme thermal conditions, ensuring stable performance in demanding environments.
