Hydrofluoric acid alkylation units destroys stainless steel pipe in months. Titanium is effective, but is about 3-5 times more expensive. The only alloy that is both high in HF resistance and not too expensive is monel 400, which has been the industry standard for more than 80 years. That is why the engineers of refining, […]

Key Differences and Applications Super duplex S32750 is more expensive than duplex S32205 for offshore oil and gas piping. It’s not just an invoice. In the wrong application, the use of standard duplex as opposed to super duplex can result in catastrophic chloride stress corrosion cracking, failed systems and expenses that far outweigh any material […]

The wrong alloy selection of a high-temperature heat exchanger can be way too costly and six months of expensive downtime in the process. This is no longer a possible scenario. A specification error in the materials used in a single component can have implications that ripple through an industry, like in the petrochemicals, power generation […]

Refractory anchors are mechanical anchorings that attach refractory linings to the interior shell of high-temperature industrial equipment like furnaces, kilns, boilers and reactors. These anchors are designed to withstand multiple stresses of intense heat, thermal cycling, mechanical vibration and chemical attack which will ensure that the lining will not shift, crack or detach during operation.  […]

One of the most disruptive and expensive issues that engineers and plant maintenance staff deal with in various industries is a leak in a tube fitting. In both oil and gas, pharmaceuticals, chemical processing and power generation, even a small instrumentation fittings leakage may cause unplanned shutdowns and safety risks at work, as well as […]

Galvanic corrosion is regarded as the most prevalent and most expensive type of metal corrosion observed in construction, marine, oil and gas and industrial piping systems. Knowledge on the nature of galvanic corrosion, its initiation, and prevention is a must to engineers, procurement groups, and plant managers who deal with dissimilar metals on a day-to-day […]

When it comes to aligning heavy machinery, levelling a structural base plate or correcting the valve clearances, the choice of shim thickness is not negotiable. Any change of a fraction of a millimetre could cause vibration, wear prematurely or even disastrous equipment failure. This guide describes what shim thickness is, the importance of shim thickness, […]

Bimetal products are highly engineering materials which are produced through permanent bonding of two different base metals to produce a composite material which integrates the best performance attributes of the two metals. Bimetallic products unlike single-metal products are designed to provide stronger performance, high thermal conductivity, high corrosion resistance and cost-effectiveness, which cannot be realized […]

When engineers, OEM purchasers, and procurement teams are confronted with the issue of selecting an industrial plastic material, four names are again and again mentioned: PTFE, Nylon (PA), Delrin (POM/Acetal), and PEEK. These engineering plastics have different sets of characteristics (including chemical resistance, temperature capability, friction, load-bearing strength, dimensional stability, machinability, and cost) and each […]

Be it the layout of a new line of high pressure process, or the replacement of existing connections in a chemical plant, one choice makes system reliability more than almost any other; that of instrumentation tube fitting. Get it wrong and you will have a leak free and maintenance-light connection, which may last decades. Get […]
