Piping & Layouts

Providing precise equipment layouts, 3D piping routing, stress analysis, and comprehensive isometric drafting for process plants and refineries.

Efficient and Compliant Piping & Plant Layout Design

ASHAAH LIMITED delivers high-end piping engineering and layout design services for industrial installations, processing plants, and offshore platforms. Our focus is on maximizing safety, improving operability, and facilitating smooth maintenance access.

Our team coordinates multi-disciplinary inputs to design optimized plant plot plans, equipment arrangements, and detailed piping runs. Using state-of-the-art CAESAR II software, we perform static and dynamic stress analysis to verify pipe flexibility, check nozzle loading limits on rotating machinery, and specify optimal structural supports, hangers, and expansion joints.

Frequently Asked Questions

Common enquiries regarding our piping engineering and layout design services.

ASHAAH LIMITED designs process piping systems in strict accordance with major international codes and standards to guarantee operational safety, reliability, and code compliance across petrochemical facilities, hydrocarbon processing plants, and refineries. Our core engineering design calculations for process plant piping conform strictly to ASME B31.3 (Process Piping), which governs material selection, pressure design, piping components, and inspection parameters. For high-pressure steam generation facilities and power utility networks, we execute designs in compliance with ASME B31.1 (Power Piping). Additionally, we integrate industry-specific interface standards, including API 610 (Centrifugal Pumps for Petroleum), API 617 (Axial and Centrifugal Compressors), and API 650 (Welded Tanks for Oil Storage), ensuring correct nozzle loading limits. For expansion joints and mechanical thermal flexibility solutions, our designs follow the Expansion Joint Manufacturers Association (EJMA) guidelines. Adhering to these rigorous codes prevents mechanical failure and ensures safe facility operation.

CAESAR II is the engineering industry's standard software package used to perform comprehensive static and dynamic pipe stress analysis on complex process piping systems. It allows engineers to build detailed mathematical models of piping networks, accounting for physical properties, temperature changes, and external environmental forces. The software evaluates thermal expansion loads, self-weight, internal fluid pressures, wind, seismic accelerations, and dynamic transient forces such as fluid slugging or water hammer. The primary purpose of this analysis is to ensure that operating stresses remain within the allowable limits defined by codes like ASME B31.3. Additionally, CAESAR II calculates the forces and moments acting on equipment nozzles to prevent overloading of sensitive machinery like pumps and compressors. ASHAAH LIMITED performs detailed CAESAR II analysis to specify custom pipe support configurations, spring hangers, guide restraints, and structural stops, thereby guaranteeing long-term mechanical integrity.

ASHAAH LIMITED provides a complete suite of engineering design deliverables for piping layout projects, taking concepts through to detailed, construction-ready packages. Our core deliverables include overall Site Plot Plans and Equipment Layout drawings, ensuring optimized space usage, operability access, and safe egress paths. We produce detailed 3D piping routing models using AutoCAD Plant 3D and AVEVA E3D, from which we generate precise Piping General Arrangement (GA) drawings and Piping Isometric drawings complete with weld maps and dimensions. Our packages include CAESAR II Pipe Stress Analysis reports, specifying calculated stresses, nozzle load verifications, and pipe support locations. Furthermore, we compile secondary steel pipe support detail drawings, spring hanger datasheets, and comprehensive bulk Material Take-Off (MTO) bills. These highly accurate, multi-disciplinary documents enable EPC contractors to coordinate fabrication and construction without field clashes or costly material waste.
