Trunnion vs Floating Ball Valve: When to Specify Each - Complete Guide
Floating and trunnion-mounted ball valves are both API 6D certified for pipeline service, but they differ fundamentally in seating mechanism, pressure rating, operating torque, and ability to provide double-block-and-bleed (DBB) isolation. Choosing the wrong type leads to seat leakage, excessive operating torque, or unnecessary cost. This guide sets out the engineering rules for selecting between them.
API 6D Pipeline Valves - Complete Procurement Guide for Indian Projects
API 6D - 'Pipeline and Piping Valves' - is the primary international standard governing valves for oil and gas transmission pipelines. For procurement engineers on ONGC, GAIL, IOCL, and EPC pipeline projects in India, API 6D compliance is a contractual requirement. This guide covers what API 6D requires, how to write a purchase specification, and what to check in a supplier's data book.
API 6D Ball Valves: Complete Technical Guide for Pipeline and Oil & Gas Applications
API 6D is the international standard for pipeline valves used in oil and gas transmission systems. This guide covers everything procurement engineers and project managers need to know about API 6D ball valves - from design requirements to testing protocols.
