Seeking help with domestic chemical engineering PID CAD software

Domestic chemical PID CAD software has seen rapid development in recent years, with some products already possessing strong competitiveness in terms of functionality, compatibility, and local support services. Here are several software options worth considering, along with their features for your reference: 1. ZW CAD PID (Guangzhou ZW Longteng). Features: A specialized PID module developed on the ZW CAD platform; compatible with AutoCAD format, supports GB/T standard symbol libraries, and provides tools for quick drawing of pipes, instruments, equipment, etc. Advantage: The user interface is highly similar to AutoCAD, resulting in low learning costs ； It supports data export and integration with Excel, making it suitable for small to medium-sized projects. Applicable scenarios: General-purpose PID design, especially suitable for AutoCAD users transitioning to it. 2. Haochen CAD PID (Suzhou Haochen Software) Features: Integrated into the Haochen CAD platform, it provides specialized symbol libraries for industries such as chemicals and power generation, and supports intelligent wiring as well as automatic generation of bill of materials (BOM). Advantages: Lightweight and smooth in operation, with good compatibility with domestic operating systems (such as UOS) ； It has strong price competitiveness. Applicable scenarios: Enterprises with limited budgets or those that require localization. 3. Yingsi PID (Beijing Yingsjie Technology): Features include a chemical process design software developed independently, support for drawing both PID and PFD diagrams, a built-in component library based on ASME/GB standards, and a function for checking data consistency. Advantages: High professionalism, supports collaborative 3D factory design ； Suitable for the full life cycle management of large-scale projects. Applicable scenarios: large-scale complex projects in the petrochemical and pharmaceutical industries. 4. Kerui PID (Kerui Software) Features: Focuses on the design of process plants, integrates functions such as intelligent PID and 3D pipeline design, and supports integration with ERP/MES systems. Advantages: Localized services with rapid response, offering customized development ； Suitable for enterprises with needs for information integration. Applicable scenarios: Digital design of medium and large-scale process plants. 5. Tsinghua Swell PID (some versions): Feature: Although it is primarily designed for the construction industry, some of its toolkits support basic PID drawing, making it suitable for simple process design. Advantages: Low cost, suitable for university teaching or small projects. Note: The functionality may not be as advanced as that of professional chemical engineering software. Selection recommendations – Compatibility: If working with AutoCAD, give priority to Wangsu and Haochen ； If used independently, Insis and Kairui can be considered. Industry suitability: Petrochemical/pharmaceutical industries choose Insis ； For small and medium-sized projects, choose Wang/Haochen ； For system integration, select Kerui. Budget: Haochen and SVIL offer good cost-performance ratios ； Large enterprises can invest in Insis’ full suite of solutions. Additional notes: Open-source alternatives include DraftSight (free basic drawing capabilities) or LibreCAD (open-source, but with limited PID functions). Cloud trends: Some domestic software products now offer web versions (such as Haochen Cloud CAD), which are suitable for collaborative work. It is recommended to try the demo version or contact the manufacturer to obtain industry cases, and conduct an evaluation based on the actual project requirements. Domestic software generally has advantages over foreign software (such as AutoCAD PID) in terms of localization support and after-sales service.
