Safety First

When conveying acids and chemicals around your work site, – plant or mine site – you should be asking yourself (1) is it safe and (2) what if this leaks? In some instances chemicals can cause serious harm or injury, and possibly resulting in death. If you have pipes conveying chemicals in over head applications or walkway areas or in high risk environmental impact areas then the importance of the safety of these piping systems is critical. You also need to be mindful of dripping product/chemical from your pipes which can lead to the pipe cracking or collapsing. A double containment system for pipes is the solution for safety and also the environment. No further leaks into the soil and contaminating the work site for our future. GF does offer a dual containment system for new applications as well as a retro piping system for existing applications. The Double Containment Piping Systems exhibit significant benefits for both the user and the system Builder. They reduce the possibility of danger where environmentally hazardous media are conveyed within the plant, in addition to cutting down on potential downtime in production. Further and most importantly they provide protection for people, equipment, buildings, soil, air and water. When properly installed, Double Containment Piping Systems meet the relevant legal requirements and help to lower insurance premiums. In the case of damage, an integrated leak detection system makes it possible to locate the leakage point rapidly. The investment of a Dual containment system will soon pay off. With international approvals from Cyanide codes on gold mines to environmental protection in water treatment plants in National...

It’s in the cleaning and the priming

In a world where time is of the essence, cleaning and priming thoroughly is often overlooked. It’s also overlooked because of the simplicity and ease of the jointing process.  Yet, many premature failures with solvent jointing are due to dirt contamination within the joint and/or not priming the jointing surfaces with solvent cleaner. Solvent cement jointing is commonly used for plastics including UPVC and CPVC, also ABS and Nylon. In the case of pressure pipe applications, pipe cleaning and correctly priming the surface with solvent is paramount. Thermoplastic pipes are compounded with additives to ensure that when extruded, they will form a surface gloss to maintain the aesthetics of the piping system. Typically, these additives include waxed based materials. The pipes are also marked in ink for identification and to provide traceability to the manufacturer. The surface gloss and ink markings are a source of contamination that needs to be removed in preparation for solvent cement jointing, otherwise the joint strength can be compromised. During the pipe priming and cleaning stage, technicians should use a solvent cleaner and apply it over the joint area with a clean, lint free fabric or tissue. The solvent penetrates into the surface of the material to ensure a residual amount is present over the duration of the curing time when the joint develops its strength. The correct application of solvent or priming fluid will remove the surface gloss leaving a dull and soft finish. After cleaning the joint area, technicians should be careful not to touch or contaminate it with any foreign matter. So, if you are tasked with having to implement or...
