UNIROR Pigging Calculator

Features
Read full description

The UNIROR Pigging Calculator is the essential mobile tool for pipeline engineers, project managers, municipal water utility technicians, and industrial cleaning professionals. Plan your pipe cleaning and maintenance projects accurately, quickly, and directly on-site or in the office. With this app, you can calculate all the crucial physical parameters for pipeline pigging in just a few taps. KEY FEATURES & CALCULATIONS: β€’ Effective Diameter: Calculate the clear internal diameter of your pipe by factoring in single-sided dirt and deposit accumulation. β€’ Pipeline Volume: Determine the exact volume (in mΒ³) of the pipe section to be cleaned, based on length and nominal diameter. β€’ Water Demand: Compute the required water flow rate in liters per second (l/s) and cubic meters per hour (mΒ³/h) at a standardized pigging speed of 1.0 m/s. β€’ Estimated Waste Amount: Get an estimate of the cleared debris volume. INTELLIGENT PIG RECOMMENDATIONS: Select your specific cleaning objective (e.g., pipe emptying, sludgy, pasty, solid, or hard deposits, rust removal, drying, disinfection, or nominal diameter changes). The app instantly recommends: 1. The correct pig for your initial Test Run (e.g., Test pig, Sponge pig). 2. The optimal pig for your operational Cleaning Run (e.g., uncoated or fully coated pigs, criss-cross coated, lip pigs, or heavy-duty configurations with steel/plastic brushes and studs). ADDITIONAL HIGHLIGHTS: β€’ "Pigging Explained Simply": View our educational animated introductory video and pipeline schematics directly within the app. β€’ Direct Shop & Support Integration: Browse matching products on our website and contact UNIROR support with a single tap. β€’ Dual Language: Full localization in English and German. Streamline your logistics, prevent pipeline damage from incorrect pig choices, and guarantee the success of your pipe-cleaning projects.
