Smaller bridge construction and maintenance can benefit from cost-efficient Herculon type D sliding bearings in capacities up to 60 tons per bearing.  A challenge facing builders and operators of thousands of smaller bridges throughout Australasia is ensuring such structures can flexibly and cost-efficiently cope with internal movement and stresses caused by changing loads, vibration, thermal expansion and other common attritional factors.  The ability to provide cost-efficient and maintenance-free solutions to such issues is especially important to road and pedestrian access projects demanding high safety, such as those undertaken in metropolitan infrastructure projects, including health and carpark facilities.  Such capabilities are also important in remote area service vehicle and pedestrian access facilities, such as those providing supply, exploration and service routes to mining and energy and oil and gas projects, where movement within access structures is caused by factors such as climate, changing uses and delivery of plant including conveyors, motors, turbines and reticulation systems.  “Low maintenance is equally important also to government authorities as they face demands from local businesses to refurbish and renew private and public regional infrastructure,” says Mr David Booty, Manager, Hercules Engineering (a division of Cut To Size Plastics).  “It is estimated* that there are more 30,000 timber and concrete bridges maintained by local authorities, for example, of which more than a quarter are in poor or fair condition,” *Source: National State of the Assets Survey 2015.  Many of these are smaller road bridges or pedestrian walkways or bridges and could benefit from a no-maintenance, cost-efficient solution provided by Hercules Engineering through its range of Herculon Type D Bearings (HLD/SG, HLD/FF & HLD/FX), which are widely proven on applications ranging from steel and concrete beam engineering structures through to materials handling and processing facilities.  Herculon HLD Bearings are part of a comprehensive range of Hercules composite […]

WIA (Welding Industries of Australia) has announced the expansion of its industry leading Weldmatic range of MIG and multi-process welding machines, which now includes three new inverter models; the 250i, 350i and 500i. With all three welding machines utilising inverter technology, they feature sophisticated electronic controls, high frequency switching and high frequency transformers, to achieve consistent and controlled weld output for the professional welder. The Weldmatic 250i is a 240V multi-process industrial welder, suitable for everyday use by vehicle smash and exhaust repairers, fencing contractors and general maintenance applications in workshops and factories as well as on construction and mine sites. Capable of handling MIG, Stick and Lift-TIG welding, the 250i is a versatile and portable machine capable of gas shielded welding of aluminium, mild and stainless steel, as well as gas shielded cored wires and gasless flux-cored wires. Designed for every-day use, the control panel allows easy selection of gas and wire type, with infinitely variable voltage and wire speed, indicated on the digital display. However, unlike other similar machines on the market, the Weldmatic 250i features a 4-roll wire drive which improves wire feed consistency, plus it can accommodate 15kg wire spools. Using a 15kg spool means the machine suits the light industrial user as 15kg spools work out far cheaper per kg than smaller 5kg spools; in short the 250i can improve the welder’s productivity while reducing operating costs at the same time. The Weldmatic 250i is also supplied with a tradesman quality MIG gun with 3.6m cable complete with euro connector for easy fitting and removal, plus a 3m work lead, an industrial twist lock electrode holder, gas regulator, a range of tips and suitable drive rollers. Weighing in at just 25.5kg, the 250i comes supplied with two handles, making it an easy two-person lift and […]

For more than half a century, municipal councils, as well as industrial and mining companies throughout Australia and New Zealand have invested billions of dollars into equipment and infrastructure to process waste water and sewage. Corrosion of this infrastructure, and in some cases the subsequent leakage, costs industry in excess of $1B each year. The main assets that are impacted by corrosion in waste water treatment plants (WWTP) are the pipelines, storage tanks, clarifier ponds and sewage channels. As much of the WWTPs infrastructure is ageing, it is starting to require refurbishment or replacement. One method of refurbishment of these assets is to carry out surface repairs and then apply protective coatings. These coatings must be strong, flexible and resistant to chemical attack. Corrosion particularly affects the submerged parts of structures in WWTPs. “Special consideration has to be given when coating structures in sewage treatment plants,” stated Dennis Baker, Special Projects Engineer at Gold Coast-based Rhino Linings Australasia (RLA). “One of the more corrosive by-products of sewage is hydrogen sulphide gas.” “Hydrogen sulphide reacts with moisture on surfaces in a waste water plant and bubbles up to form sulphuric acid which really loves concrete,” added Baker. Hydrogen sulphide (H2S) attacks the cement, copper, iron and silver which gradually degrades the structure. In the case of a pipeline, this may ultimately result in the collapse of the pipe wall. The modern requirement for capping storages in order to control excessive odours has the drawback of also increasing gas concentrations. One type of coating from RLA that is ideally suited for waste water treatment is spray applied Polyurea. The company has been working with this material since the early 1990s and now manufactures in Australia a range of consistent formulations which are suitable for a variety applications. Pure Polyurea is a relatively […]

Low maintenance Air stroke actuators from Firestone provide a compact and easily installed way to continuously orient solar trackers’ payload towards the sun to optimize the amount of energy produced from installed power generating capacity. The rubber and fabric actuators – distributed throughout Australia by Air Springs Supply Pty Ltd – can be used to solve the problem of stationary solar collection panels becoming inefficient as the sun shifts from a 90-degree angle to the panels. Usually inflated or deflated by standard fixed or mobile compressed air (typically 7 bar (100 psi), they move photovoltaic systems to minimize and angle of incidence between the incoming sunlight and a photovoltaic array. Alternatively, an ingenious actuation alternative uses the expansion and contraction of Freon gas as it is heated and cooled within the actuators to extend and retract them and change the angle of the collection panels. “Airstrokes are particularly beneficial for commercial installations, where continuous focusing of the arrays through single or dual-axis arrangements enhances energy returns. Such installations – sometimes in remote locations and subject to climatic extremes over 24 hours – need extremely reliable actuators to continuously reposition payloads such as solar panels, reflectors, mirrors or lenses,” says Air springs Supply Sales and Marketing Manager Mr James Maslin. Airstroke bellows offered by for use by solar engineers and installers have been proven in widespread heavy duty industrial actuation throughout Australia, including providing millions of cycles of service on conveyors and mineral processing screens and vibrators, where they have to withstand dust, heat, moisture and extremes of Outback climate. “They are identical in construction to the airbags proven in truck and train suspension so they are extraordinarily tough. In addition to having no internal rods of seals to wear – unlike conventional metal cylinders – they have the ability to […]

One of Australia’s premier flange management companies, Projem, has used the latest Enerpac bolt tensioning technology to achieve outstanding flange sealing accuracy and tool reliability on a major project in the coal seam gas basin west of Brisbane. Projem is a specialist company, with branches in Gladstone and Brisbane and a strong focus on safety and quality. They offer a comprehensive flange management package to ensure everything is inspected and approved through all steps when completing bolted connections. They use a range of Enerpac bolting tools, which ideally complement the safety and quality focus. “In the past 18 months we’ve used Enerpac equipment to tension over 500 flange connections and it shows very little wear and tear,” says Mr Nathan Peachey, Mechanical Engineer, Projem. “All we need to do is calibrate the tensioning pump at appropriate intervals to keep the pressure as accurate as possible and Enerpac helps us with that too,” says Mr Peachey. In their recent Queensland project, Enerpac GT bolt tensioners were combined with an ATP-1500 air pump, as Projem worked on two new compressor stations and the main feed connection point on a pipeline to a Gladstone processing plant. They also assisted with pipe cutting and preparation of heavy wall pipes as well as on-site installation of pipework at Gladstone, which is a major gas processing hub for the State of Queensland, where coal seam gas has grown to become the dominant source of gas, supplying over 88 per cent of the Queensland market and over 98 per cent of remaining proved and probable gas reserves. The Enerpac tensioners, in capacities up to 2,845kN (320 ton) at 1500 bar, are particularly suitable where operators want to achieve known and accurate bolt loads across multiple applications, such as pipelines and flanges. Enerpac territory manager, SE Queensland and […]
