ECO FRIENDLY INDUSTRIAL ADVANCEMENTS

When production requires small batches and runs, the least efficient component of the process is the heating of both the curing ovens and pre-treatment solution tank.

Rinsing the metal to be power coated with a pre-treatment solution is important because it ensures a uniform application. PB Metal Finishing Systems has designed a method of increasing the energy efficiency of production using their new Spray Save system.The Spray Save system’s innovative solution takes advantage of available oven space by adding a heat exchanger to capture latent heat that would otherwise be wasted. The system is comprised of a closed, coupled pumping system that is fully valved and controlled complete with non-return valves. “Pre-treatment solution is taken at a low level from the tank thereby circulating the coldest area of the tank and also keeping the solution in movement and is then pumped through the stainless steel schedule 10 fully welded and tested heat exchanger. The return of the solution is passed back to the process tank continuously.”

At the beginning of the shift both the oven and pre-treatment tank burner should be switched on. Although the heat exchanger has the capacity to fully heat the pre-treatment tank, turning both on initially will save time. They estimate that during normal shift, the normal run rates of the pre-treatment tank heating can be reduced from 6.5 hour to only 1.5 hours. This happens without any addition load on the curing oven. This reduction in required heating translates into direct saving for operator.

CONSTRUCTION PROGRESS MEETING

onsistent, regular commissioning (Cx) team meetings are essential to maintain the progress of the project and the momentum of the commissioning process.

The schedule of meetings shall be defined, documented, and included in appropriate bid documents during the design stage (monthly construction phase Cx team meetings are recommended). Team members at meetings must be authorized to make commitments and decisions for their respective parties. The typical agenda for construction phase commissioning team meetings shall include items such as previous action items, outstanding issues, schedule review, new issues, etc.

In addition to regular meetings, the commissioning agent (CxA) is responsible for preparing monthly commissioning process reports during the construction phase. These reports shall include at a minimum the following information:

WHAT DOES A CONSTRUCTION WORKER DO?

Construction workers work on all construction sites, doing a wide range of tasks from the very easy to the extremely difficult and hazardous.

Although many of the tasks they do require some training and experience, most jobs usually require little skill and can be learned quickly.A construction worker typically does the following:

  • Cleans and prepares construction sites by removing debris and possible hazards
  • Loads or unloads building materials to be used in construction
  • Builds or takes apart bracing, barricades, forms (moulds that determine the shape of concrete), scaffolding, and temporary structures
  • Digs trenches, backfills holes, or compacts earth to prepare for construction
  • Operates or tends equipment and machines used in construction, such as concrete mixers
  • Helps other craft workers with their duties
  • Follows construction plans and instructions from the people they are working for

Construction workers do a variety of construction-related activities during all phases of construction. Although most are generalists—such as those who install barricades, cones, and markers to control traffic patterns—many others specialize. For example, those who operate the machines and equipment that lay concrete or asphalt on roads are more likely to specialize in those areas.

The following are occupational specialties::

  • Building homes and businesses
  • Tearing down buildings
  • Removing hazardous materials
  • Building highways and roads
  • Digging tunnels and mine shafts
