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 …

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 …

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 …
