Valve Supplier for Linde Engineering

Linde plc — Engineering Division · Munich, Germany (Linde Engineering)

Linde Engineering (division of Linde plc) designs and builds air separation units (ASUs), LNG liquefaction plants, hydrogen production plants (SMR/electrolysis), and ethylene cracking furnaces globally. Linde Engineering is a leader in cryogenic technology and hydrogen infrastructure — their plants require specialised cryogenic valves (SS 316L, A350 LF2), oxygen-service clean valves (oxy-clean), and hydrogen-compatible materials (ASME B31.12). Projects in India (Reliance Jamnagar, ONGC NRL), Middle East, and globally.

Certification Requirements for Linde Engineering Supply

Linde Engineering Approved Vendor List (AVL)BS 6364 (Cryogenic valves — extended bonnet, impact testing)ASME B16.34 pressure-temperature ratingsASME B31.12 (Hydrogen piping and pipelines)Oxy-cleaning certificate and degreasing protocol for oxygen-service valvesCharpy impact testing (EN ISO 148-1) at −196°C for cryogenic materialsEN 10204 3.1 / 3.2 material certificates with PMI

Linde Engineering's global procurement is coordinated from Munich with regional offices in Mumbai (India), Shanghai (China), and Chennai. For Indian and Southeast Asian projects, Mumbai procurement sources cryogenic and standard process valves from qualified Indian manufacturers. Cryogenic valve requirements demand specific factory capabilities — cryogenic testing at −196°C, extended bonnet design, and helium leak testing. Linde Engineering's specifications (LES-XX-XXXXX) are project-specific and incorporate their proprietary cryogenic valve design requirements beyond standard API/ASME.

Frequently Asked Questions — Linde Engineering Valve Supply

Can Vajra supply valves directly to Linde Engineering projects?
Yes. Vajra Industrial Solutions can supply valves directly to Linde Engineering facilities and through EPC contractors executing Linde Engineering projects. We have experience with the documentation, inspection, and certification requirements typical for Industrial Gases, LNG, Hydrogen & Chemical Engineering projects.
What certifications are needed for valves used in Linde Engineering facilities?
Linde Engineering typically requires: Linde Engineering Approved Vendor List (AVL), BS 6364 (Cryogenic valves — extended bonnet, impact testing), ASME B16.34 pressure-temperature ratings, ASME B31.12 (Hydrogen piping and pipelines). All Vajra-supplied valves can be provided with these certifications as standard.
How quickly can Vajra deliver valves for Linde Engineering projects?
Stocked items are dispatched same day or next day from Vadodara. Custom or large-bore valves typically require 4–12 weeks depending on specifications. Emergency supply for plant shutdowns is given priority. We serve clients across India and internationally.
Does Vajra accept third-party inspection for Linde Engineering projects?
Yes. We welcome third-party inspection by any NABL/ILAC-accredited or internationally recognized TPI agency. We coordinate documentation, witness testing, and dispatch according to the inspection plan.
