Outstanding safety from PTT-ME hinges on the best hydraulic tools backed by the best maintenance and calibration

Precision hydraulic tools are vital to engineering, maintenance and construction companies servicing the oil and gas industries.

Not only must their tools be capable of initial accuracies to within fractions of millimetres and minute percentages of force applied, but also they must be able to sustain such accuracies over the lifetime of the tool, to ensure repeatability of performance and integrity of joints and fabrication tolerances on infrastructure they maintain.

Correct verification of the calibration of hydraulic bolting tools, for example, provides accurate and consistent fastening of plant and machinery ranging from pipelines, tanks and pressure vessels, through to mobile machinery such as heavy trucks, earthmoving and tracked vehicles during servicing and maintenance.

“Both initial accuracy and then ongoing calibration are absolutely vital to safety. This is true of all hydraulic tools, but particularly to fastening tools such as torque wrenches and multipliers. Such tools all periodically require testing to determine whether the torque output of a tool remains accurate - and then correction of any tools requiring recalibration so output matches the preset readings,” says Enerpac SE Asia, which works closely with distributors such as CAPE Industrial to ensure compliance with top world standards of safety and calibration.

Enerpac SE Asia is part of the globally respected Enerpac organisation specialising in 700 bar hydraulic technologies and extreme force tools, operating in 30 countries, including Singapore, where Enerpac SE Asia is headquartered, with its long-established service network extending into Brunei, Cambodia, Hong Kong, Indonesia, Laos, Malaysia, Myanmar, Mongolia, Pakistan, Philippines, Taiwan, Thailand and Vietnam.

Enerpac and CAPE Industrial are extensively involved in supplying and calibrating hydraulic technology used by the maintenance division of Thailand’s largest oil and gas company, PTT Maintenance and Engineering Company Limited (PTT-ME), which has been involved in more than 160 projects in Thailand and South-East Asia. Enerpac provided a large range of tools to PTT-ME, including hand and electric pumps, hydraulic cylinders, torque wrenches and other maintenance tools, which are serviced every year by CAPE Industrial.

The Enerpac tools perform a range of maintenance tasks in PTT-ME’s central workshop, adjacent to the headquarters of PTT Global Chemical Group, located in Rayong Thailand, which provides oil and gas, chemical, petrochemical, plastics and power plant services. It currently services all of South East Asia and is looking to expand internationally in the future.

“Enerpac are a good brand with a good reputation,” says Mr Ratchapon Yansabuy, Maintenance Manager, PTT-ME. “What was particularly impressive to us was that they were willing to provide modifications after service to customise the tools to fit PTT’s exact sizing specifications,” he said.

“Enerpac also has many product layers. We can buy all the tools we need from the one source and know that they are going to be safe and reliable in heavy duty applications,” Mr Yansabuy said.

Enerpac and PTT-ME have enjoyed a strong relationship for more than 15 years, based on safety, reliability and performance. CAPE Industrial performs a routine maintenance service once a year.

“We’ve always had excellent service from CAPE. They are able to calibrate all the tools so that they are operating at optimum efficiency and comply with all of our strict safety standards,” said Mr Yansabuy.

Enerpac technologies utilised at PTT-ME include:

  • Torque wrenches, used by PTT-ME for pressure testing, include the W series torque wrenches, which weigh from only 1.4-12kg yet have terrific and precisely repeatable torque from 2712-47450 Nm. They are complemented by the equally versatile S series of double-acting square drive wrenches, which extends from 2.7-31kg with outputs of 1898-34079 Nm.
  • Hand pumps and cylinders are combined to lift machines and parts up to 100 tonnes. Enerpac’s New ULTIMA two-speed hand pumps feature an innovative design that provides greater ease-of-use with handle effort reduced by up to 20 percent without compromising speed or performance.
  • RC heavy duty cylinders in capacities from 10-50 tons, complemented by double-acting long-stroke RR cylinders designed for the toughest job site uses and with precision designed for high-cycle industrial uses.

Enerpac RC cylinders are a workhorse cylinder proven globally for reliability and precision, while the long-stroke RR models permit jobs to be completed with reduced set-up and stroke cycles.

  • CLSG508 single-acting heavy lift cylinders with integrated stop ring to provide piston blow-out protection for extremely arduous tasks. The CLSG series – available in capacities from 50 to more than 1000 tons, can be fitted with bolt-on grooved and removable tilting saddles for optimum load stability.
  • Heavy duty ERS 30 CaterrollerTM load skates, with low profile for stability and load access and low rolling resistance for easy transportation. These are complemented by LW series 16-ton Hydraulic Vertical Lifting Wedges, requiring a very small access gap of 10mm and featuring an interlocking wedge design to eliminate first step bending and risk of slipping out.
  • Posi-Lock hydraulic pullers, which provide a high force hydraulic system for effortless pulling of large components. Available in two and three-jaw configurations, the pullers feature a patented “Safety Cage” jaw retention system designed to enhance operator safety, increase operational precision, permit efficient one-man operation and minimise the possibility of damage to components being worked upon.
  • S6000 square drive hydraulic torque wrenches, designed for simplicity of use, reliability and accuracy with precisely repeatable torque. Their lightweight, ergonomic design provides easy handling even in applications with limited space or accessibility.
  • ZA4 series modular air hydraulic pumps, which features a high efficiency pump design with higher oil flow and bypass pressure and enhanced two speed operation to reduce cycle time for improved productivity.
