About Projectmaterials
The world's most comprehensive free knowledge base for piping engineers and procurement professionals.
Who We Are
Projectmaterials is a Zurich-based company specializing in piping procurement for oil & gas and industrial projects. Founded in 2018, we serve EPC contractors, plant owners, and engineering firms worldwide with procurement automation software and technical resources.
Our wiki, launched alongside the platform, has grown into the largest free technical reference for piping materials on the internet. Every article is written, reviewed, and maintained by professionals with direct, hands-on experience in EPC project execution.
Our Mission
Our mission is to provide the world's most comprehensive, accurate, and freely accessible knowledge base for piping engineers. We cover pipes, valves, flanges, fittings, gaskets, bolts, structural steel, and process equipment according to international standards including ASME, API, ASTM, and EN.
Too much technical knowledge is locked behind paywalls, scattered across PDFs, or buried in outdated manuals. We believe that every engineer, from a graduate in Lagos to a senior piping lead in Houston, deserves instant access to reliable, well-organized reference material.
Our Expertise
Our editorial team consists of piping engineers and procurement professionals with decades of combined experience in EPC projects across the Middle East, Europe, Southeast Asia, and the Americas. Contributors have worked on upstream, midstream, and downstream facilities ranging from FPSO topsides to LNG terminals and petrochemical complexes.
Every article is reviewed by industry specialists before publication. We cross-reference original standard documents (ASME B16.5, API 600, ASTM A106, EN 1092, and many others) to ensure technical accuracy. When industry practices evolve or standards are revised, we update our content accordingly.
What We Cover
This wiki is one of the largest technical resources for piping materials available online, with content growing every month.
Beyond articles, the wiki includes engineering calculators, unit conversion tools, dimension charts in PDF format, a piping quiz with 825 questions across 11 categories, and a searchable supplier directory to help engineers find the right manufacturer for any project requirement.
Standards & References
Technical accuracy is non-negotiable. All content on this wiki references official standards and codes published by recognized bodies. We cite original sources so readers can verify information and consult the full standard documents when needed.
We do not reproduce copyrighted standard text. Instead, we explain and contextualize the requirements in plain language, with dimensional data, material grades, pressure-temperature ratings, and practical guidance that working engineers need.
