Floating head heat exchangers are a type of shell and tube heat exchanger designed to accommodate thermal expansion and contraction of the tube bundle. This design is particularly useful for high-pressure applications where significant temperature differences can occur between the shell-side and tube-side fluids.
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 spiral heat exchanger consists of two spiral-wound channels, one for each fluid. The two channels are separated by a partition, and the fluids flow in opposite directions through the channels. This counter-current flow arrangement maximizes heat transfer efficiency. Spiral heat exchangers are a...

This section exists for one reason above...
Learn how heating boilers unintentionally cross into ASME Section I power boiler classification, what inspectors look for, and how to avoid costly compliance surprises.
What is a Three-Phase Separator? A three-phase separator uses gravity to separate produced well fluid into gas, oil, and water phases. Installation of these vessels occurs near the wellhead, and they come in horizontal and vertical configurations. Produced well fluids consist of various amounts...
Sand Separators. In the oil and gas industry, it is more commonly known as a separator and is a core component of extracting oil from earth and sand. Sand separators are an integral part in protecting downstream production equipment from well-formation sand and/or frac...
Modular boilers are compact, factory-assembled boiler units designed to work together in a series — offering scalable steam or hot water generation based on demand. Rather than relying on a single large boiler, modular systems operate with multiple small units that can be staged...
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...
Pictured above: Fabricator inspecting weld on skid Skid-Mounted Units: ASME-Compliant Modular Engineering Solutions Skid-mounted units, often referred to simply as “skids,” are self-contained process systems or equipment packages that are fabricated off-site and delivered as turnkey modules. These units are engineered and built to...
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.

Compact heat exchangers are a type of heat exchanger designed to provide a high heat transfer rate in a small footprint. They are commonly used in applications where space is limited, such as in aerospace, automotive, and electronics industries.
Sand separators are crucial components in various industries, including oil and gas, water treatment, and manufacturing. They are designed to remove solid particles, such as sand, dirt, and scale, from liquid streams. The choice of sand separator depends on various factors, including the type...
Radiographic Testing (RT) is a powerful NDE technique widely used in the manufacturing of pressure vessels and boilers. It involves the use of ionizing radiation to penetrate the material and create an image of internal features.
When it comes to designing pressure vessels, one of the most critical decisions engineers face is selecting the right material. In high-pressure environments, the wrong choice can lead to catastrophic failure, regulatory violations, or costly downtime. The right material, on the other hand, ensures...
ASME boiler codes can sound intimidating, especially if you’re not an engineer by trade. The good news? You don’t need to memorize the Code to understand the basics.
