Dear Industry Partners,

The 4th Innovation Exchange Conference on Petroleum & Petrochemical Material Procurement and Supply Chain Management will be grandly held at the Beijing Petroleum Science & Technology Exchange Center from October 23 to 24, 2025. TVN Sealing (Booth No. B80) is honored to receive the exhibition invitation. We will systematically display our latest technological achievements and innovative solutions in the field of high-performance sealing during the event.

As a leading domestic enterprise in sealing technology, TVN Sealing is always committed to providing reliable and efficient sealing system support for the petroleum and petrochemical industry. At this exhibition, we will focus on showcasing the following core technical products:

Part 01 High Pressure & Ultra-High Pressure Seals

Backed by multiple national patented technologies, our high-pressure sealing products maintain outstanding performance under extreme working conditions. The maximum operating pressure of dynamic seals can reach above 700 MPa. They have been successfully applied to key equipment including hydraulic nuts, plunger pumps and isostatic presses, representing the advanced level of domestic high-pressure sealing technology.

Part 02 Rotary Sealing Solutions

Our self-developed rotary seals achieve an excellent balance between high-speed and high-pressure working conditions, with a maximum linear speed of 40 m/s. They deliver exceptional performance in Roots blowers, centrifuges and other equipment, delivering reliable sealing guarantee for rotary machinery.

Part 03 Flexible Custom Turned Seals

Supported by technical reserves of more than 200 cross-section profiles, we provide fast-response customized services for customers. No molds are required, sample delivery can be completed in as short as 1 hour, and the maximum machining diameter reaches 3900 mm, effectively satisfying all kinds of non-standard demands.

Part 04 Sealing Products for Special Working Conditions

Our spring energized seal series adopts an innovative combination of PTFE sealing rings and stainless steel springs. They retain stable performance under harsh environments such as high temperature and strong corrosion, and are widely used in high-end sectors including petrochemical, aerospace, food and pharmaceutical industries.

Part 05 High-Performance Sealing Material System

We also supply a full range of sealing materials including modified PTFE and specialty polyurethane, delivering material-level solutions for performance optimization of all types of seals and advancing the process of domestic substitution of critical materials.

Our technical team will conduct in-depth on-site communication with you and offer professional recommendations tailored to diverse working condition requirements. Whether you face challenges of extreme pressure, special media or long-cycle operation, we look forward to delivering trustworthy solutions for you.

We sincerely invite you to visit us at Booth B80 to jointly discuss the development trends of sealing technology, and work together to continuously improve the safety and reliability of petroleum and petrochemical equipment.
