Overview: Q2 2026 ASME Boiler and Pressure Vessel Code Meetings

CEI and Paulin Research Group remain deeply engaged in the ongoing developments of ASME pressure equipment codes. Our engineers participate in ASME code committee meetings each quarter, contributing technical expertise and tracking proposed revisions firsthand. This regular involvement keeps us closely aligned with regulatory changes and allows us to plan software updates proactively, helping our tools evolve in step with emerging requirements that impact pressure vessel and piping design worldwide.

Section IX & Section VIII Code Meetings | May 2026

In the week of May 11–14, , CEI and Paulin Research Group representatives -- Tiradej Bunyarattaphantu, P.E., Santiago Laris P.E. -- attended several ASME code committee meetings in person at the Sheraton Downtown Denver in Denver, CO. These meetings include: 

Section IX Committee Meetings

• Subgroup on Welding Qualifications 

• Subgroup on Materials (IX) 

• Subgroup on Brazing 

• Subgroup on General Requirements (IX), of which Tiradej Bunyarattaphantu is a member 

• BPV Committee on Welding, Brazing, & Fusing 

Section VIII Committee Meetings

• Working Group on Design by Analysis 

• Subgroup on Design, where Santiago Laris serves as a member of the Resource Development Group 

• Subgroup on General Requirements (VIII) 

• Subgroup on Heat Transfer Equipment, where Tiradej Bunyarattaphantu serves as Secretary 

• BPV Committee on Pressure Vessels  

Key Insights from the Meetings

• Section VIII is voting on an item that will move paragraph UG-20(f) to a new paragraph in UCS-66. They are also reviewing the Code Case for fixed tubesheets using the unified design theory.

• Section IX is about to review a proposal from the task group rewriiting the tube-to-tubesheet rules. These changes involve creating a new Article in Section IX to handles all the rules for tube-to-tubesheet welding.  

• The Subgroup on Heat Transfer Equipment discussed reorganization of 4.18 to consolidate and move the equations for the tubesheet types into one location to reduce the replication of equations throughout 4.18. Changes to better align Part UEJ, Part UHX, and Part UEB with all other Common Rules changes were presented.  

• The BPV VIII Working Group on Design by Analysis, reporting to the Subgroup on Design, continues the development of requirements for protection against cyclic, creep, and buckling failure modes.

Meet Our Code Experts

Our engineering representatives, Tiradej Bunyarattaphantu, P.E., and Santiago Laris, P.E., bring substantial technical depth to their roles within the ASME code committees. Tiradej, who has been with CEI for more than a decade, participates in multiple ASME subgroups and currently serves as Secretary of the Subgroup on Heat Transfer Equipment. Santiago, a Texas A&M University graduate and an integral part of the Paulin Research Group support team since 2020, contributes extensively to resource development and technical initiatives across several committee activities.
