oil and gas
3 in-depth engineering guides on oil and gas — specification, selection, testing and procurement.
Everything on oil and gas
Vajra's engineering team has published 3 technical guides covering oil and gas for industrial valve selection, specification, testing and procurement. Browse the full set below.
Choke Valve Guide for Oil & Gas Production: Positive, Adjustable & Trim
The choke valve controls the flow and pressure of a producing well - taking the largest pressure drop in the system through erosion-prone trim. This guide covers choke types, trim selection, erosion control, and the API 6A standard.
Valve Selection for Oil & Gas Upstream Operations
Upstream oil and gas operations demand the highest valve reliability - wellhead blowouts and pipeline failures are catastrophic. This guide covers Christmas tree configurations, NACE sour service requirements, fire-safe testing, and the API 6D compliance framework for upstream valve procurement.
Valve Actuators for Oil & Gas in Oman and the Middle East: Selection Guide
Valve actuators for Oman and Gulf region oil & gas projects face unique selection challenges - extreme ambient temperatures (up to 55°C), remote locations with unreliable instrument air, ADNOC/PDO/OQ company specifications, and offshore/onshore corrosive environments. This guide covers actuator type selection, sizing, fail-safe logic, and Middle East project-specific requirements.
