piping class
3 in-depth engineering guides on piping class — specification, selection, testing and procurement.
Everything on piping class
Vajra's engineering team has published 3 technical guides covering piping class for industrial valve selection, specification, testing and procurement. Browse the full set below.
Piping Class and Valve Selection: ASME Class 150 to 2500 Explained
Piping class - ASME Class 150 through 2500 - is the foundation of every industrial valve specification. The wrong class means the valve cannot handle the process pressure-temperature conditions. This guide explains ASME pressure class rating methodology, P-T rating tables, when RTJ replaces RF at Class 600, and the body material selection matrix by class.
How to Write a Valve Datasheet: Complete Specification Guide for Engineers
A poorly written valve datasheet is the single biggest source of wrong deliveries, project delays, and field failures. This guide explains every field in a valve datasheet - from basic sizing to actuator details - so your valve arrives exactly as intended.
Valve Piping Classes and Specification Sheets: A Complete Engineering Guide
Piping classes (pipe specs) are the backbone of process plant valve procurement - they define which valve types, materials, end connections, pressure classes, and inspection requirements apply to every pipe in the plant based on fluid service and operating conditions. This guide explains how piping classes are structured and how to translate them into accurate valve orders.
