Coalescing gas separators are designed specifically for the removal of mist, fog, and dust from gas streams. These contaminants usually exist with the bulk of the particles having diameters considerably less than 10 microns; therefore, standard separators or scrubbers are not capable of effectively...

A horizontal separator is a cylindrical vessel that is oriented horizontally. When a gas-liquid mixture enters the separator, the heavier liquid phase settles to the bottom of the vessel, while the lighter gas phase rises to the top. Horizontal separators are a common type...

Liquid Separators are excellent choices for applications where large slugs of liquids need to be prevented from entering the vacuum pump. Capturing these liquids before they can enter the vacuum pump will reduce pump failure, oil degradation, and production downtime.

The selection of appropriate materials is a critical aspect of B31.1 piping design. The choice of material depends on factors such as temperature, pressure, corrosion resistance, and cost. By carefully selecting materials and considering the factors discussed above, engineers can design piping systems that...

In a horizontal three-phase separator with an overflow weir, fluid enters the vessel through an inlet and immediately hits an inlet diverter. The sudden impact and change of direction helps to release the gas by breaking the surface tension of the liquid.

ASME® Section VIII, Division 2 provides an alternative design approach to pressure vessel construction by allowing higher design stress levels in exchange for more rigorous design analysis, material testing, and quality control.

Fluidized bed boilers (FBBs) use a unique combustion method where solid fuel particles are suspended in an upward flow of air — creating a fluid-like state. This allows for highly efficient combustion at lower temperatures with improved emissions control.

The difference between the U designation and the UM designation is related to size. However, this is not the only difference between the two. UM designated pressure vessels are not required to undergo the same inspection regimen as the larger, U stamped pressure vessels.

ASME® Section VIII, Division 1 provides the foundational framework for designing, constructing, and inspecting pressure vessels.

A scraped surface heat exchanger consists of a cylindrical shell with a rotating shaft inside. The shaft is fitted with blades or scrapers that continuously scrape the inner surface of the shell. This scraping action prevents the formation of product buildup on the heat...

Microchannel heat exchangers are a type of heat exchanger with channels that have characteristic dimensions in the micrometer range. These tiny channels offer significant advantages in terms of heat transfer efficiency and compact design. In a microchannel heat exchanger, the two fluids flow through...

Natural gas dehydration is the process of removing water vapor from natural gas. A gas dehydration system is used by oil and gas producers to dehydrate natural gas into a state where it can be sold downstream.

Electric boilers use electricity to generate steam or hot water — eliminating the need for fuel combustion. Unlike traditional boilers, there are no burners, gas valves, or flue stacks. Heat is generated through electrical resistance or electrode-type elements, making them clean, quiet, and often...

Two-Phase Spherical Separators operate on the principle of gravity separation. When a gas-liquid mixture enters the vessel, the heavier liquid phase settles to the bottom, while the lighter gas phase rises to the top. The unique spherical shape of the vessel promotes efficient separation...

A UM-Stamp is a certification mark issued by the National Board of Boiler and Pressure Vessel Inspectors (NBBPVI). It authorizes a manufacturer to repair and alter existing pressure vessels and boilers. This certification ensures that repairs and alterations are performed in accordance with the...

The PP-Stamp is a certification mark issued by the National Board of Boiler and Pressure Vessel Inspectors (NBBPVI). It signifies that a manufacturer is authorized to weld, fit, manufacture, and install piping and components that attach to external piping used for power boilers and...

A fire-tube boiler is a type of boiler where hot gases pass through tubes, which are surrounded by water. It's one of the most common boiler types used in low- to medium-pressure steam applications — especially in heating systems, commercial buildings, and smaller industrial...

The ASME® B31.1 Code for Power Piping is a widely recognized standard that provides guidelines for the design, fabrication, and installation of piping systems for power plants. This code ensures the safety and reliability of piping systems by establishing rigorous design and construction standards.

If the S-Stamp is the finish line, the Authorized Inspector (AI) is the gatekeeper holding the stopwatch. Before that stamp ever touches a boiler, inspectors are verifying far more than weld quality or paperwork completeness. They’re answering one critical question:

In industrial operations, boiler downtime isn’t just an inconvenience—it’s a profit killer. Whether it’s lost production, emergency repair costs, or compliance penalties, a boiler failure can have far-reaching impacts. Fortunately, many of these issues are preventable with a strong, proactive maintenance strategy. In this...
