Mechanical Seals Components Supplier

Regardless of the size of the gate or stop log Plasti-Fab products will have superior physical properties and be substantially lower in overall weight. When this maintenance procedure is required on competitor;s gates - where the seals are installed on the guide frame - customers are in for an expensive and very involved operation. Weight can be a major consideration in flow control gates for both manual and electric actuator installations. When electric actuators are employed the size of the operator must be significantly bigger and more expensive, plus excess weight will put extreme stress, wear and tear on the expensive electric actuator. The added overall operational cost for gates that have the seals on the guide frames can add thousands of dollars to the actual cost of the gate. Stop logs are commonly used in remote Natural Resource applications. There is no air in the mold and there is no chance of entrapping air in the laminate matrix of the finished product. The gate can be taken to a maintenance shop or serviced on site. Osmosis is a naturally occurring process. If the gate is manually operated an extremely heavy gate or stop log can turn a routine function into an all-day operation. Plasti-Fab gates and stop logs are price competitive with all competitive fiberglass and metal products, but offer a vastly superior flow control device with reduced life-cycle costs, and they stand behind the product with the best warranty in the industry! The attention to detail in their product is the result of over 40 years; experience supplying gates and stop logs to customers across the globe. There is no weak-link, and environmental exposure along with infrequent (or routine) operation will not stress their gates and stop logs.

An ENGINEERED COMPOSITE using "sandwich" construction will have the absolute best strength to weight ratio. This is followed by a substantial cleaning procedure to gain access to the guide frames from the invert to the top of gates travel point.. Maintenance personnel then have to enter a typically confined and not overly comfortable area spending significant amounts of time removing and replacing seals. Plasti-Fab flow control products such as: Heavy Duty Tite Seal (HDTS) sluice gates Wedging Tite Seal slide gates Stop gates Stop Logs Have a number of unique features incorporated into the product to enhance their daily use and long term reliability and longevity. Depending on the size, an ENGINEERED COMPOSITE gate or stop log from Plasti-Fab can be 20% to 40% less in overall weight compared to competitive offerings. First the channel must be de-watered or the flow through the pipe blocked.The seamless construction of the Plasti-Fab gates and stop logs differs greatly from other fiberglass offerings of competitive products that are fabricated with FRP panels which are then attached to a metal skeleton. The corrosion resistant characteristics of these materials, along with their advanced and proven design, engineering expertise and manufacturing techniques allow Plasti-Fab to offer a 25-year warranty against corrosion and oxidation. In fact, all Plasti-Fab gates and stop logs meet AWWA guidelines for leak rates and when in use routinely perform at levels where leakage is so minimal it is barley measurable and greatly surpasses AWWA standards. Plasti-Fab, by using the vacuum infusion manufacturing process, removes all air from the mold before injecting the resin. Depending on the chemical and abrasive composition of the water and the frequency of operation eventually the neoprene "J" bulb type seals are going to wear and need replacement. The maintenance staff will have unencumbered access to the gate to quickly and comfortably replace the seals. There is no potential of porosity or air entrapment in the part - the air has been removed. This device allows the customer to fine tune the sealing function of the gate at installation applying consistent pressure to the non-seal side of the gate - resulting in most effective sealing possible.

Moisture related oxidation and corrosion on metal gates are issues that need constant attention from the first day of installation. Nothing offers the strength to weight ratio like a Plasti-Fab ENGINEERED COMPOSITE product. Metal gate manufacturer;s recommendations to "exercise" the gates on a regular basis is testament to the fact that if you do not "open and close the gates on a very regular basis" corrosion and oxidation will quickly occur and prevent you from performing the gates primary function - to open and close. Water will penetrate - move in and out - through most any substrate it comes into contact with. This has a negative impact on the short-term and long-term performance and lifecycle of the device. The site specific variables of every flow control gate and stop log project will require consideration of the weight of the device. No other manufacturer of flow control products offers this type of performance assurance on China Sealing Rings their gates and stop logs. All too frequently, metal stop logs are stolen for their scrap metal value. Depending on the size of the gate or stop log and the amount of head pressure the gate or log is subject to there are numerous operational and economic variables to be considered. When sluice gates of average or larger dimensions are needed most metal gates will require the use of a wall thimble adding dramatically to the overall cost of the gate and substantially increase contractor installation costs in time and materials. From the largest sluice gate to the smallest hand operated stop gate. Plasti-Fab engineering, design and manufacturing expertise and focus on performance is integral to every gate and stop log they manufacture.

With Plasti-Fab gates having the seals on the gate the operator can be removed from the stem of the gate and it can then be extracted from the guide frame. The Plasti-Fab gates and stop logs are made in a closed mold where the air is vacuumed out prior to infusing the corrosion resistant resin. Channels will not need to be de-watered and pipes will not need to be blocked or flow diverted. The Plasti-Fab gates and stop logs are one piece! There are no points of contact or panels that must be affixed to a frame. Plasti-Fab ENGINEERED COMPOSITE stop logs can offer a far superior product with no value to those so inclined to steal unguarded products. Plasti-Fab HDTS sluice gates are also designed with a wedging mechanism at the invert of the gate. All Plasti-Fab gates and stop logs are fabricated using polyester and vinyl ester corrosion resistant thermoplastics. Moisture penetration via porosity in the laminate can corrode the metal core materials in the flow control gate or stop log and it will begin to "wick" the fiberglass reinforcement and weaken the part. With an expected long life-cycle for a sluice gate the maintenance procedure of replacing seals may occur several times. For instance, Plasti-Fab HDTS sluice gates have the seals affixed to the gate, not the guide frame. In conventional FRP laminates the micro porosity air voids create a conduit for the water to move within the laminate matrix. That;s why they put bilge pumps on battle ships
