n oil processing facilities, hydraulic pumps are essential workhorses. They drive equipment, control pressure systems, and support the movement of fluids through refining and storage networks. But hidden behind every efficient hydraulic motion is a system of seals doing a quiet yet vital job—containing pressure, preventing leaks, and protecting components from wear. For engineers tasked with maintaining or upgrading oil plant operations, the question is not simply “which seal to use,” but rather: “What is the best sealing approach for this specific hydraulic pump application?” Let’s take a closer look at how seal solutions are developed and selected for oil plant hydraulic pumps. The Environment Defines the Requirements Oil plants are not uniform in their conditions. Seals used in upstream exploration equipment, for example, face different challenges than those in midstream transfer stations or downstream processing facilities. However, several shared conditions affect seal selection: Exposure to high-pressure fluids Frequent thermal cycling Presence of abrasive particles or chemically aggressive substances Continuous operation with limited downtime allowance These demands require seals that not only resist wear and heat but also maintain dimensional stability and performance over long service intervals. Common Seal Types for Hydraulic Pumps in Oil Plants Rather than using a single sealing component, hydraulic pumps often rely on a combination of seals to manage pressure, motion, and fluid separation. These typically include: Rod Seals: Positioned on the cylinder rod to prevent hydraulic fluid leakage. In oil plant applications, rod seals must cope with pressure spikes and fluid compatibility challenges. Materials like FKM (fluorocarbon rubber) or PU (polyurethane) are common choices. Piston Seals: Located within the cylinder to divide pressure chambers, these seals ensure the correct motion of the hydraulic piston. For oil plant conditions, PTFE-based or NBR-reinforced seals are often preferred. Wiper Seals: Designed to block external contaminants such as dust or oil residues from entering the cylinder. These are essential in dusty or grease- laden environments common in outdoor or mechanical sections of oil facilities. Static Seals (O-rings and Backup Rings): Used where components are fixed, these prevent fluid leakage at rest. HNBR (hydrogenated nitrile rubber) O-rings with PTFE backup rings are widely used in systems where both heat and pressure are present. Customized Solutions: More Than Off-the-Shelf Components Many oil plant systems are custom-designed. Older systems may have non-standard configurations, while newer equipment might require seals with advanced material properties. In such cases, custom-engineered seals are developed by analyzing the following: Operating temperature range Maximum and minimum pressure Type of hydraulic fluid used Speed and frequency of motion Available space and groove dimensions By adjusting lip profiles, selecting reinforced materials, or incorporating anti-extrusion rings, engineers can create a sealing system that matches the machine rather than forcing the machine to match the seal. Maintenance Strategy and Seal Lifespan Even the best seal will eventually wear, especially in continuous-duty environments like oil plants. That’s why choosing a sealing solution is also about planning for replacement cycles. Seals that are easy to install or inspect without dismantling the entire pump can significantly reduce maintenance time. Some advanced sealing solutions include visual wear indicators, split ring designs, or composite seals that integrate multiple functions in one piece. Finding the right solution starts with understanding the environment, the application, and the long-term performance expectations. With the right approach, seals in hydraulic pumps become quiet enablers of efficiency in even the most demanding oil plant environments.

　　Hydraulic systems are integral to the operation of steel plants, powering a range of heavy machinery, from presses to continuous casting machines. Hydraulic cylinders, in particular, are pivotal in controlling movement and force in various processes, including mold oscillation, rolling mill adjustments, and material handling. However, the efficiency and longevity of these hydraulic cylinders largely depend on the seals that keep hydraulic fluids contained and protect the internal components from contamination. 　　In the context of steel plants, where high pressures, temperatures, and harsh operating conditions are the norm, the selection of hydraulic cylinder seals becomes a crucial factor in ensuring smooth operations and minimizing downtime. Let’s explore the different types of seals commonly used in steel plant hydraulic systems. 　　1. Rod Seals 　　Rod seals are placed on the piston rod of a hydraulic cylinder and are responsible for maintaining the pressure of the hydraulic fluid while preventing the leakage of oil. These seals also protect the cylinder from external contaminants such as dust, dirt, or steel shavings. 　　Typically, nitrile rubber (NBR), polyurethane (PU), or fluorocarbon (FKM) are used for these seals due to their resistance to both high temperatures and abrasion. In steel plants, where the ambient temperature and friction levels are often extreme, FKM seals are commonly used due to their superior thermal stability. 　　2. Piston Seals 　　Piston seals prevent hydraulic fluid from leaking through the piston, ensuring that the pressure generated inside the cylinder is maintained. In high-pressure applications typical of steel plants, these seals are often designed with dual-lip or quad-ring configurations to enhance sealing performance and durability. 　　For materials, NBR and HNBR (hydrogenated nitrile rubber) are widely used because of their ability to withstand moderate to high pressure and their resistance to wear. However, in environments where extreme temperatures or exposure to chemicals (such as hydraulic oils) is present, FKM and PTFE (polytetrafluoroethylene) seals are preferred due to their enhanced chemical resistance and high-temperature tolerance. 　　3. Wiper Seals 　　Wiper seals, also known as scraper seals, are essential in steel plants for preventing external contaminants, such as slag, dust, and moisture, from entering the hydraulic system. These seals are typically installed at the rod- end of the cylinder. 　　The primary function of the wiper seal is to “wipe” off debris from the piston rod as it extends or retracts, maintaining the cleanliness of the hydraulic cylinder. Polyurethane (PU) and rubber-metal composites are often used for wiper seals, as they offer good abrasion resistance and can perform under harsh conditions. 　　4. Bearings and Back-up Rings 　　In some steel plant hydraulic cylinders, bearings and back-up rings are used alongside primary seals to support the hydraulic piston and prevent excessive wear. Bearings are used to support radial forces, while back-up rings help prevent extrusion of seals under high-pressure conditions. 　　PTFE is often the material of choice for back-up rings due to its low friction properties and resistance to chemical attack. For bearings, bronze or high-strength steel is frequently utilized in combination with seals to ensure long-term performance under heavy-duty operations. 　　5. Valve Seals 　　In certain hydraulic systems, valve seals are used to ensure proper flow control and pressure regulation. These seals are critical in maintaining the integrity of the fluid passage in the valve assembly. For steel plant applications, O-rings, lip seals, and V-rings are commonly used in valve systems. 　　The material selection for valve seals largely depends on the fluid compatibility, pressure requirements, and temperature tolerance. Nitrile rubber (NBR) is typically chosen for general-purpose use, while FKM is preferred in systems exposed to high temperatures or aggressive chemicals. 　　Key Considerations for Seal Selection in Steel Plant Hydraulics 　　When selecting hydraulic seals for steel plant applications, several factors must be considered: 　　Temperature Range: Seals must be able to handle high temperatures typical in steel production environments, which can reach up to 200°C or more. 　　Chemical Resistance: Many steel plant processes involve exposure to aggressive chemicals and lubricants, so seals must be resistant to chemical attack. 　　Pressure and Load Requirements: Hydraulic cylinders often operate under high pressure, and seals must be able to maintain integrity under such conditions. 　　Contamination Resistance: Seals must be able to withstand contamination from steel dust, slag, and other particles without failing. 　　The role of hydraulic cylinder seals in steel plants is far more than just a mechanical function—they are integral to the efficiency and reliability of the entire hydraulic system. Understanding the different types of seals, from rod seals to wiper seals and piston seals, allows plant engineers and maintenance teams to make informed decisions about sealing solutions.

Every tunneling project begins with the silent strength of engineering beneath the ground. While the spotlight often falls on the massive cutterheads of shield machines, few stop to consider what keeps the operation stable and leak- free—sealing systems. DEDE provides general parts and also produces seals that meet the specific needs of underground construction. This includes abrasion management, temperature endurance, and fluid resistance, all packed into precision- engineered sealing profiles. Whether facing groundwater intrusion or high rotation speeds, these seals are developed to perform under sustained mechanical and environmental stress. Manufacturer Direct Supply—What It Means for You One notable aspect of DEDE's business model is its direct supply approach. This eliminates intermediate channels and allows clients to receive sealing components straight from the production floor. The result? More predictable lead times, easier technical communication, and reliable product traceability. This model supports large infrastructure contractors and machine repair teams alike, especially when working with TBMs that demand frequent seal replacements or unique dimensions. Durable Performance for Shield Machines The sealing rings produced by DEDE are specifically crafted for use in shield tunneling systems, including earth pressure balance (EPB) machines and slurry TBMs. These machines operate under substantial axial and radial pressure, often encountering abrasive soil and fluid-laden environments. To meet these conditions, DEDE applies rubber compounds such as FKM and HNBR, combined with fabric reinforcement or metal frameworks, depending on the function. Lip-type configurations and grooved geometries are designed to prevent internal leakage while withstanding shaft misalignment or unexpected pressure spikes. These seals are not standardized across machines. Instead, DEDE offers customization based on shaft diameter, housing structure, rotation speed, and lubricant exposure, ensuring a functional fit rather than a forced compromise. Beyond Just a Seal—An Integrated Component Within a tunnel boring system, a sealing ring does more than stop leaks. It isolates internal systems, protects high-precision bearings, and helps maintain pressure balance within the machine. DEDE’s seals are tested to retain functionality even after long intervals between inspections, reducing the risk of emergency shutdowns during active tunneling. In addition, some designs incorporate dust lip structures and multi-material composite layers to further extend lifespan, especially when working in sediment-heavy strata.
