Clad Fabrication
November 3, 2023 Explosion-bonded clad material is commonly used for pressure vessel construction. The clad liner (cladder) is explosively bonded to the backer material (backer). The alloy-clad material can be bonded to most metals. The most common types of backer materials are SA-516-70 (P no. 1 material) and SA-387 Gr. 11 (P no. 4 material). During the fabrication … Continue reading "Clad Fabrication" ...Read More
Production Impact Testing
November 2, 2023 Do you know vessel manufacturers produce Production Impact Test Weld Coupons? Production impact testing is fairly common for vessels with shell walls greater than 1.5” in thickness. Production impact testing ensures that the actual production materials, including weld metal, have the proper toughness requirements to meet ASME Code and applicable specifications that apply to your … Continue reading "Production Impact Testing" ...Read More
ASME Section VIII, Division 2
October 4, 2023 For many, ASME Section VIII Division 2 is a mystery, for both Fabricators and Mechanical Engineers. Why? Even though it has been around since its creation in 1968, most engineers and fabricators never get to use it. (1) It takes additional certification and a U2 stamp, (2) additional software for ASME Section VIII Division 2 … Continue reading "ASME Section VIII, Division 2" ...Read More
Gaskets – How do they work and why do we need them? Part 2
October 3, 2023 If you are a fabricator, one of the last things on your list is ordering the gaskets. If you are an Engineer, the last thing on your list is specifying gaskets. If you are an owner and you hare having a problem sealing flanges, the number ONE thing on your mind is gaskets. Many times, … Continue reading "Gaskets – How do they work and why do we need them?

Pressure Vessel Quality Control Requirements – Part 2
September 15, 2023 Understanding what is required for boiler and pressure-vessel manufacturers can help scheduling and cost assessments Material Requirements Materials of construction for the vessel delivered to the manufacturer must be inspected to verify compliance with the Code. For plates, the manufacturer shall verify that the slab number, heat number and material grade marked on the plate … Continue reading "Pressure Vessel Quality Control Requirements – Part 2" ...Read More
Pressure Vessel Quality Control Requirements – Part 1
September 6, 2023 Understanding what is required for boiler and pressure-vessel manufacturers can help scheduling and cost assessments Pressure vessels are common in the chemical process industries (CPI) and they range widely in size and complexity. Process engineers may be tasked with inspecting a new pressure vessel or with witnessing hydrostatic testing of a vessel. In addition, engineers … Continue reading "Pressure Vessel Quality Control Requirements – Part 1" ...Read More
Piping Design for Potentially Lethal Chemicals Part 2
September 2, 2023 Code Requirements The introduction to the ASME-B31.3 piping code states that “The designer is cautioned that the code is not a design handbook…” In stating this, ASME is explaining to the reader in very few words that this code will not provide pointers on the best way to route a piping system, how to support … Continue reading "Piping Design for Potentially Lethal Chemicals Part 2" ...Read More
Piping Design for Potentially Lethal Chemicals – Part 1
September 1, 2023 As you can imagine, the requirement for piping in and out of lethal service pressure vessels would have additional requirements as well. Integrity and reliability are critical for piping and equipment that handle chemicals with extreme health hazards. Working in close proximity to the high pressures and temperatures commonly found in the chemical process industries … Continue reading "Piping Design for Potentially Lethal Chemicals – Part 1" ...Read More
