Tianjin Uranus Hydraulic Machinery Co., Ltd. designs high pressure hydraulic cylinders with a strong focus on safety and reliability. We understand that failures in high-pressure systems can be catastrophic, so we incorporate multiple safety features into our cylinder designs. Our cylinders are built with robust materials and include safety factors that exceed typical industry standards. We use heavy-wall tubing and forged components to contain the high pressure. The sealing systems are designed with redundancy, often including both primary and secondary seals, and are selected for their ability to maintain integrity under extreme pressures and temperatures. For applications where cylinder integrity is critical, we can design with burst-proof features such as steel containment sleeves. We also incorporate safety features such as pilot-operated check valves to prevent unintended movement in case of hydraulic line failure. Each cylinder is serialized, and we provide full traceability of materials and manufacturing processes. Our testing includes pressure cycling to verify long-term integrity. For a high pressure hydraulic cylinder that prioritizes safety and reliability, our designs are engineered to give you peace of mind. To discuss your safety requirements, please contact us.

Frequently Asked Questions

What safety features are incorporated into your double acting hydraulic presses?

Our double acting hydraulic presses incorporate multiple safety features to protect operators and equipment. These include light curtains or safety fencing, two-hand anti-tie-down controls, emergency stop buttons, overload protection devices, and hydraulic safety valves that prevent unintended movement in case of pressure loss. We also incorporate pressure relief valves, end-of-stroke cushioning, and audible alarms. All safety systems are designed to comply with relevant international safety standards and can be customized to meet specific customer requirements.
Tianjin Uranus has over 30 years of experience serving the metallurgical industry. We have supplied hydraulic cylinders and systems to steel mills and foundries for applications such as continuous casting, rolling mills, furnace equipment, and shears. Our products are designed to withstand the extreme conditions of this industry, including high temperatures, shock loads, and pervasive contamination. We understand the critical need for uptime in steel production and engineer our solutions for maximum reliability and serviceability in mill environments.
Our servo hydraulic cylinders are ideal for testing applications because they deliver precise, repeatable force and position control with low friction and high stiffness. We offer cylinders with integrated feedback sensors such as LVDTs or magnetostrictive probes, enabling closed-loop control for accurate test results. For high-frequency applications, we provide cylinders with hydrostatic bearings that offer zero friction and infinite wear life. Our cylinders are designed for the dynamic demands of materials testing, fatigue testing, and structural testing, ensuring reliable performance over millions of cycles.
Our hydraulic nuts provide uniform, precise bolt tensioning, which is critical for maintaining joint integrity under extreme vibration and shock loads. They eliminate the inaccuracies of torque wrenches and reduce the risk of bolt fatigue or thread galling. We offer custom-engineered nuts for specific thread sizes and load capacities, with safety features such as pressure relief valves and visual indicators. Our hydraulic nuts are used in applications such as wind turbines, large presses, and metallurgical equipment, where reliable, repeatable clamping is essential.

Customer Reviews

David Miller

We needed a high pressure hydraulic cylinder for an offshore subsea application, with requirements for corrosion resistance and high reliability. Tianjin Uranus designed a custom cylinder with stainless steel components and special coatings that have performed exceptionally well in the harsh marine environment. The cylinder has been deployed for over a year with no issues. The Uranus engineering team was knowledgeable about the unique demands of subsea applications and provided a solution that met all our specifications. I highly recommend their custom high-pressure cylinder capabilities.

Dr. Peter Chen

Our component test rig requires high pressure hydraulic cylinders that can deliver up to 10,000 psi for burst and fatigue testing. Tianjin Uranus supplied cylinders that have been operating reliably for over two years. The cylinders are built with forged components and feature redundant sealing systems that have prevented any leaks. The precision machining ensures smooth operation, and the integrated pressure sensors provide accurate data. The Uranus team provided excellent support and documentation. These cylinders are critical to our testing capabilities.
