Vajra's engineering team has published 3 technical guides covering ASME B31.3 for industrial valve selection, specification, testing and procurement. Browse the full set below.
Gate Valve Installation Guide - Step-by-Step Procedures, Orientation and Best Practices
Correct gate valve installation is critical to valve performance and service life. This step-by-step guide covers pre-installation inspection, orientation requirements, flange bolt tightening sequence, hydrostatic testing, and commissioning best practices for gate valves in industrial piping systems.
Valves for Industrial Oxygen Service - O2 Compatible Materials, Cleaning & Standards
Oxygen service is one of the most hazardous valve applications - the combination of enriched O2 atmosphere with hydrocarbon contamination, high velocity, or adiabatic compression can cause ignition of the valve body itself. Correct material selection, O2 cleaning, and system design are essential.
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.
