Good point! …👍🏼 Often you see stuff like this… in addition it’s not uncommon to see “Bellow Vent” (Pipe Plug/Off) … Improper Installation. Solution: Valve Traveler/ Installation Checklist.

Outlet restrictions will cause built-up back pressure during discharge. Built-up back pressure on an unbalanced valve will act as spring pressure. This can cause chatter, an increase in set pressure, and the PRV will be unable to reach capacity, leaving the vessel unprotected against overpressure. This is a great example of non-conformance of NBIC Part 4, Sec 3.2.3 c) - Inspection Requirements for Installation Condition. Code doesn’t allow restrictions of any kind at the inlet or outlet of a relief valve. If the outlet is 1”, the outlet piping must also be at least 1” or larger.

#Installers, do you know how to check insulated pipes for corrosion? Our latest blog explains ways to check for corrosion under insulation (CUI) https://lnkd.in/eNH8qtH4 #engineers #contractors #insulation #ArmacellAnswers

EVER WONDER? Why you have no external corrosion but near-neutral SCC is prevalent? ·     Your Cathodic Protection surveys show “adequate” instant-off protection ·     Shouldn’t adequate CP shift the pH of the steel out of the near-neutral range? ·     Would a Swain pipe clamp-on ammeter help correlate CP current flow with locations of SCC and/or corrosion? ·     Shouldn’t you have external corrosion if your coating was shielding the cathodic protection? ·     Does soil type and drainage and seasonal water table play a role? ·     Should you increase your CP current at the risk of coating disbondment? #pipelineintegrity #stresscorrosioncracking #pipeline #group10engineering

Whether you are a building owner or an installer, it is imperative to know that a plumbing system has been installed correctly and that there are no nasty surprises hiding around the corner, such as a pipe detaching from its connection. As you can imagine, this could lead to flooding and unprecedented damage to a building. But how can you be certain that pipework has fully connected and remove this risk? X-Ray vision perhaps?! 🕶 We have solved this issue by equipping our Uponor Multi-Layer Composite (#MLC) Pipe system with a joint inspection window for full reviewing capabilities. Unlike traditional metal press systems which rely on the engineer following an installation process with 100% accuracy, the Uponor MLC system provides complete peace of mind. It’s useful observation window shows the position of the pipe inside to ensure it is fully engaged before the pressing is made, so that joints are installed correctly first time - and eliminating doubt. Find out how the MLCP solution can be included on your next project: https://lnkd.in/dj23dS6i #construction #heating #hvac #pressfit #UponorUK #MovingWater

CORROSION SCABS When carbon steel is exposed to external corrosion, a layer of corrosion product forms on the affected area, known as a corrosion scab. As the owner of the equipment, it is important for you to determine the remaining wall thickness beneath this scab in order to assess its safety for operation. In the case of pipe sections with scabs, one approach is to conduct a radiographic inspection of the cross-section to measure the remaining material. However, there are limitations imposed by safety regulations, particularly regarding the strength of the radioactive source. Realistically, obtaining clear radiographic images for pipes with a diameter exceeding 6 inches becomes challenging. So, what alternatives are available for larger diameter pipes or for scabs found on vessels and tanks where radiography cannot be utilized? I'd be interested to hear if anyone utilized the technique shown in video. #assetintegrity #inspection #corrosionprotection #corrosionprevention #oilandgasindustry #refinery

Repairing valve boxes in the road can be a frustrating and time-consuming task. Traditional methods, such as using hot patch, often come with their own set of challenges. Obtaining small quantities of hot patch and transporting it to the repair site can be logistically difficult. Additionally, closing down the road and waiting for the hot patch to cure can cause significant traffic disruptions. Even after the repair is complete, the use of stone backfill can lead to settlement and sinking over time, compromising the integrity of the repair. Fortunately, there is a solution that addresses all of these issues: the combination of QC10 and Permanent Road Repair products. This innovative approach not only streamlines the repair process but also ensures a long-lasting and durable restoration. By following this process, municipalities, contractors, and utility companies can achieve efficient and long-lasting valve box repairs, minimizing traffic disruptions and reducing the risk of future settlement or sinking. https://lnkd.in/d5EnhNig

CUI of Plant and Pipework Corrosion Under Insulation of process plant and pipework is largely connected to steel components. ❌ Failures have happened with containment lost as a result of localised corrosion that was developing under insulation undetected. When steel comes into touch with water and has access to oxygen, it corrodes. Contributing factors to water entering the insulation: - Poorly designed/ installed protective finish or cladding. - Cladding joint sealant breakdown. - Mechanical damage to protective finish. - Cladding removed and not replaced properly. 📖 Read more here: https://lnkd.in/eh5WKQYm #CorrosionUnderInsulation #Pipework #Powertherm #CUI #Insulation #Cladding

📘 Tank Collapsed Due to Corrosion Under Insulation In the simplest terms, Corrosion Under Insulation is any type of corrosion that occurs due to moisture present on the external surface of insulated equipment. The damage/attack can be caused by one of multiple factors, and can occur in equipment operating at ambient, low, and heated services, depending upon conditions. Moreover, corrosion can occur on thermally insulated equipment that is in service, out of service, or in cyclic service. Because these surfaces are not generally available/accessible for visual examination, the onset of corrosion cannot be easily identified, and in extreme cases, severe corrosion with consequential loss of system integrity can occur. ❓ Case Study: Tank Collapsed Due to Corrosion Under Insulation!!! A 5,000 m³ insulated tank at a chemical terminal was emptied when corrosion holes were found on the roof. The tank was badly corroded. A severe gale, worsened by being funneled between other tanks, caused the rusty tank to collapse. #oil #tank #corrosion #CUI #insulation #chemical #terminal #storage #integrity #severecorrosion #mechanical #inspection #maintenance #collapse #rupture #damage #learning #process #safety #safedesing #
