Hydrocarbon and Chemical Processing
Engineers throughout Refining, Chemicals, Oil & Gas, and LNG sectors rely on PIP Practices for standardized design, engineering, procurement and construction guidance.
Supporting Safer, More Consistent Hydrocarbon and Chemical Processing Projects
PIP Practices help in the design and optimization of hydrocarbon and chemical processing facilities and methods, promoting safer, more consistent and more reliable solutions.

- Metallic Piping Systems Design
- Refractory Practices
Piping and Instrumentation Diagrams (P&ID)
PIC001 defines how P&IDs are developed and documented, underpinning process design, operations and safety lifecycle in refineries, chemical plants, upstream and midstream Oil & Gas, and LNG facilities. This valuable P&ID resource is the backbone for HAZOP studies, control system design, maintenance and management of change and works hand-in-hand with PIE001 (Process Flow Diagram Documentation Guidelines) and PSEED01 (Inherently Safer Design Guide) for process safety.

Metallic Piping Systems Design
PNC00005 (Design of ASME B31.3 Metallic Piping Systems) provides the core design framework for ASME B31.3 process piping, found inside every process unit and utility across refining, petrochemicals, gas processing and LNG trains. Further supporting these extensive B31.3 piping networks are PNC00001 (Pipe Support Criteria for ASME B31.3 Metallic Piping) and PNSC0001 (Fabrication and Examination Specification for ASME B31.3 Metallic Piping).
Refractory Practices
Hydrocarbon and chemical processing facilities depend on robust refractory linings to keep fired heaters, furnaces and reformers operating safely, efficiently and reliably. PIP Refractory Practices provide a specialized toolkit for fired equipment designers and maintainers, anchored by RFEG1000 (Guidelines for Use of Refractory Practices), which ties together best practices for lining design, material selection and quality assurance across projects.
