Stanely Material and Metallurgical Testing Lab Kannampalayam, Coimbatore, Tamil Nadu

The Pipe Joint Tester incorporates a mating flange on one end and inflatable seals beyond the joint to be tested. When the pipe joint tester is installed, the annular space between the seals becomes a fluid tight chamber, allowing the user to check the pipe joint for leakage. Joint testers are the ideal tool for pipeline joint testing and isolation applications.

General Nuclear Maintenance Plugs Stanely Material and Metallurgical Testing Laboratory offers a full range of proven tool designs for general plant maintenance. Many of our tools are utilized as primary isolation tools which have the added benefit in the “hot” zone.

M.P. series medium pressure pipe test plugs perform at the (specified) pressures common in the water supply industry, water treatment, and industrial markets (up to 100 pisg depending on pipe diameter). These medium pressure pipe test plugs offer a cost effective means of conducting tests, or isolating line sections at any interval or stage of construction. This feature is extremely useful where long runs between valves can occur, and where the ability to pull an immediate test after negotiating difficult angles, wall cavities, (elbows), or terrain, can be very reassuring. Medium pressure pipe test plugs applications have included the testing, repair, and maintenance of the following piping systems including the by-pass of damaged line sections for continued sections.

Sealfast® Mechanical Pipe Plugs feature the same lightweight aluminum construction as the LP and MP series of Inflatable Pipe Plugs. These mechanical pipe plugs are mechanically actuated by tightening a series of rim nuts around the periphery of the pipe plug. This squeezes the rubber seal into the I.D. of the pipe.  High Quality Mechanical Pipe Plugs At Stanely Material and Metallurgical Testing Laboratory we strive to offer only the best mechanical pipe plugs available today. Along with superior mechanical pipe plugs, we offer inflatable door seals, pipe pullers, we even offer custom seals. Our mechanical pipe plugs offer the following features: Long duration/long term installations Installations where seal inflation air is not available Sizes 1/2″ to 144″

Stanely Material and Metallurgical Testing Laboratory has developed tools for lifting and pulling for a variety of custom applications. Our pipe pullers have the capacity to pull heavy loads without any damage to the pipe inside diameter. The lifting devices can have redundant seals that have separate air supplies for safe operation. Call us with your application and we will work together to design for you a lifting or pulling tool that meets your needs. Applications: N Automated fabrication and assembly lines for part handling N Convenient pipe pulling and lifting tool N Motor stator lifting applications N Nuclear fuel rod handling tools

How Pneumatic Seals / Inflatable Seals Work Inflatable seals or pneumatic seals work by introduction of an inflation pressure into the cavity of the inflatable seals. This inflation pressure causes the displacement of the seals effecting a positive seal between the seals and the surface to be sealed. Once the seals inflation pressure is removed the seal returns to its uninflated position (memory). Regulated air is the commonly utilized inflatable seals medium while in some applications pneumatic (gas) or hydraulic (liquid) methods are suitable. Inflatable seals offer versatile configurations in three different planes: radially in, radially out, and axially.

LP Pipe Plug The Sealfast® Low-Pressure (LP) inflatable pipe plugs, featuring the double acting seal ring, are available in sizes ranging from 1/2 inch to 144 inches. These easy to install pipe plugs have been used for isolation of piping systems during testing, repair and maintenance, for bypassing of damaged lines, and for isolation of piping systems during construction. The L.P pipe plugs have received wide acceptance in many industrial applications including nuclear and hydro plants, chemical and petrochemical plants, water treatment plants and water and sewer lines. MP Pipe Plug The Sealfast® Medium-Pressure (MP) pipe plugs, featuring the double ring seal and locking lugs, are available in sizes ranging from 1/2 inches to 144 inches and can withstand pipe pressures up to 100 psig. Applications have included testing, repair and maintenance of piping systems, including the bypass of damaged line sections for continued service. HP Pipe Plug The Sealfast® High-Pressure (HP) mechanical plugs are available in sizes ½ inches to 144 inches with a maximum pressure rating of 5000 psig. Test ports allow testing of pipe or tubing through the pipe plug.

The high pressure pipe test plugs series of pipe plugs available from Mechanical Research & Design are available for applications that exceed 100psig. Our custom sizes include 1/2″ to 60″. Sealing can be done either internally or externally. Please provide the pipe I.D., type and pressure requirements.   High Pressure Pipe Test Plug Features: Internal and external pipe stoppers allow you to test different types of pipe and tubing. Reverse pressure (RP) stoppers allow you to isolate and test the integrity of a single weld. Thru Test Port allows testing/draining through the plug. Standard sizes are available to different configurations to suit your specific application. Engineering expertise to help you develop other non-standard sizes, configurations and applications. High Pressure Pipe Test Plug Applications: Pipelines operating over 100 PSIG. Quick and easy testing of Plain-end pipe systems.
