If you’ve ever studied the specification of a pipeline and found the size of the pipe followed by some numbers like “Sch 40” and “Sch 80,” then you’re not alone in having no idea what exactly is changed by this designation. Pipe schedule designations are one of the most confusing elements of pipe specification, but […]

A flange is a ring-shaped fitting of steel, forged or cast and secured to two sections of pipe or pipe to a valve or vessel by bolting. A gasket is compressed between two matching faces and it is this compressed gasket which provides the pressure within the line. Flanges are what makes industrial piping serviceable […]

Phosphor bronze is a copper alloy with the addition of tin and a small amount of phosphorus to provide strength. Engineers can grab it anytime they need an item to perform in an environment with repeated flexing, sliding contacts, or in a damp and corrosive environment without losing mechanical integrity. Phosphor bronze is one of […]

In industries like oil and gas, chemical processing, and power generation, an industry’s most reliable pipe joining solution for small diameter, high pressure piping is a socket weld. This guide will explain the basics of socket welding, the pros and cons, and when to use it. What Is a Socket Weld? A socket weld is […]

Steel pipes are one of the most widely used industrial products in the world. They travel through the streets of cities, up walls of factory buildings, over oil fields and across continents carrying life sustaining resources.  Steel pipes power the human circulatory system, from drinking water piping to natural gas pipes. But the selection of […]

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 […]
