A simple test instrument used by manufacturers and used to identify leaky tubes in condensers, heat exchangers and other tubular apparatus.   The Vacuum Tube Leak Tester PVLD-3000 is a simple and precise tool used for testing tubes of boilers, condensers and heat exchangers. It is the fastest and most accurate method of locating leaky tubes for plugging or replacement or installation of new tubes.   It works on the principle of vacuum in which the tool sucks the air from the tube and creates a vacuum to a desired reading on gauge. Steady reading on gauge indicates NO LEAK. If the reading on the gauge drops it indicates a tube with a LEAK.   Features of Vaccume Tube Leak Tester Only one tool necessary for testing multiple tube sizes. Built-in easy to read vacuum gauge. Multifiled exhaust for quiet operation. Lightweight and easy to use.

These tools are used typically in boilers and other larger tubes that have a light to medium deposit. These tools use patented ergonomic cutting wheels that ensure the same tooth of the cutter wheel does not touch the same spot when cleaning. This prevents grooves being formed in the tube scale. The cutters ‘fly out’ when the tool is rotated and perform cleaning action.

electric tube cleaners are environment friendly, compact and easily maneuverable units used to clean straight and curved tubes in heat exchangers, condensers, boilers and other tubular apparatus. Water consumption can be regulated as needed. Easy interchangeability of various shafts and accessories for maximum versatility.   they work by attaching a cleaning tool (to be determined on type of deposit to be cleaned) to a flexible shaft. The electric tube cleaner provides rotary motion to the flexible shaft which rotates the cleaning tool inside the tube. If needed water passes through the flexible shaft to aid in flushing out of the deposits. All electric tube cleaners are supplied with forward direction foot switch. Dual direction foot switches are available on request.   features of electric tube cleaner : water flushes through the shaft and helps remove deposits from tube. forward direction foot switch enables operator to concentrate on cleaning operation without worrying about cleaner. flexible shaft can be easily disconnected. stainless steel body for use in the harshest environments. easy interchangeability of various shafts and accessories for maximum versatility. large wheels for easy transportation. water consumption can be regulated as needed.

Used for insertion of long and heavy tube bundles into the shell of heat exchangers. Two fully automatic pull pistons are used to push the tube bundle into the shell. The pulling pistons slide on a biaxial positioning frame horizontally as well as vertically to position the pull pistons as per the diameter of the tube bundle. The unit can be easily converted into twin headed continuous tube puller or extractor.   Features of Tube Bundle Inserter Used for insertion of long and heavy tube bundles inside the shell of heat exchangers. Inserts tube bundle at rate of 3mtrs/min. Generates a coaxial force of 60 tons to insert tube bundle into the shell without any jolts thereby avoiding damages to shell and tube bundles. Can be easily converted into double headed tube puller for tube extraction.   TECHNICAL SPECIFICATIONS

THE PST SERIES TOPSIDE BOLT TENSIONERS IS ONE OF THE MOST LIGHT, COMPACT AND VERSATILE LINE OF TENSIONERS AVAILABLE:   Features Versatile Design: The PST Series standard variable tensioners are designed to provide a wide range of flexibility, covestu covering sizes from 3/4” to 5.3/4” (M-16 to M-150). Different stud sizes are accommodated by the same load cell the sa by simply changing the adaptor kit consisting of Threaded Puller, Bridge and Nut Driver. High Strength Aircraft Quality Alloy Steel: The PST Series tensioners operate at a maximum pressure of 1500 Bar covestu and are manufactured from high strength AISI 4340 alloy steel parts for long lasting trouble free performance. Stroke Indicator: The PST Series tensioners have and an exceptional stroke of 15 mm. The Integral Stroke covestu Indicator allows the piston stroke to be viewed while tensioning is in progress. A Red line on piston indicates covestu an over stoke ensuring safe operation. Safe Design in event of Piston ‘Over Stroke’: The PST series tensioners are designed so that in event of covestu over-stroke the high pressure fluid will be released from the inner side of the load cell, thus saving the operator covestu from any potential exposure. Multi Tensioning: The PST Series load cell is provisioned with two connections and this acts as a manifold for covestu multi applications. By using high pressure link hoses, any number of bolt tensioners can be connected and used covestu simultaneously. This ensures equal tightening of all bolts on the flange and reduces work time. Anti Roll, Composite Material Seals: All PST Tensioners are fitted with Anti Roll, Composite Material covestu seals for longer life and high reliability. The seals used have a low coefficient of friction so that the covestu piston can be returned to a closed position with minimal effort. PST Series tensioners can be provided piston with machined PU (poly urethane) seals if requested by the customer. Floating Piston: The unique piston design allows 2º tilt without any loss of load, preventing piston seizure covestu or damage to piston bore.
