Oil and Gas Piping Design Services

We turn piping ideas into a buildable reality. With more than 25 years of hands-on experience, Cad Drafter produces P&IDs, plant layouts, spool drawings, and full BIM piping models that reflect real field constraints and tight installation tolerances. Quick turnaround matters to you, so typical delivery for CAD and isometric outputs is one to two days for many jobs, without cutting corners on checks. We model according to established codes such as ASME B31.3 for process piping and ASME B31.8 for gas transmission, and include welding practices per API 1104 and flange standards from ASME B16.5 to specify materials, wall thicknesses, and pressure classes. Our BIM workflow links P&IDs to 3D routing and supports clash detection, stress handoff, and spooling ready for fabrication. For complex sites, including offshore, refinery, or pipeline, this keeps the project lean, auditable, and buildable.

Core Values Of Our Gas Design Company

At Cad Drafter, our work in oil and gas piping design is anchored in principles that balance safety, speed, and technical rigor. Every layout, every P&ID, and every BIM model of our gas design services is built with codes in mind, yet shaped by decades of practical experience. We adapt quickly, communicate clearly, and design with construction crews in mind, not just software outputs.

Code-Driven Engineering Accuracy

Field-Oriented Design Thinking

Transparent Project Communication

Rapid Yet Reliable Turnaround

Sub Services Of Our Oil Pipe Design

Our gas design company doesn’t just draw pipes. On the contrary, we build entire systems in CAD and BIM to serve the oil and gas sectors. These include P&ID schemes and full plant layouts. Also, the team is well-versed in spool-ready isometric drawings and stress-checked support designs. All in all, our services cover all phases of pipe designing services.

Piping & Instrumentation Diagrams (P&IDs)

We draft P&IDs showing equipment, control valves, instrumentation, flow paths, and safety interlocks. Each diagram includes tag numbers, control logic, and symbol libraries compliant with ANSI/ISA or IEC definitions. These are the backbone for process control, procurement, safety audits, and inform the 3D models that follow.

Isometric Piping Spool Drawings

Stress & Flexibility Analysis Services

Piping isn’t just about setting some hollow pipes. Thermal expansion, pressure pulsations, vibration, and surge loads matter a lot. We run stress analysis per ASME B31 codes, check flexibility via loops or guides, anchor spacing, and support reactions. This ensures your design safely handles temperature swings, thermal growth, and dynamic loads without undue fatigue or damage.

As-Built / BIM As-Built Modeling & Revision Support

Deliverables Of Our Pipe Designing Services

You get more than drawings if you choose our designers. Expect neatly organized files, fabrication-ready data, and compliance evidence. The best part is that all are checked against ASME and project specs. Fast to use on-site. Easy for procurement. Ready for fabrication. Clear revision history. Practical notes where crews need them most.

Special Digital Software Used By Our Designers

Designing oil and gas piping today requires more than basic CAD. We use sophisticated software that supports 3D routing, specification-driven modeling, clash detection, piping stress and flexibility analysis, and BIM integration. These tools let us build accurate models, check compliance with ASME B31 codes, create isometrics automatically, and coordinate plant layouts with other disciplines. These platforms also enable laser-scan as-built verification, material take-offs, and smooth transitions from design to fabrication.

Aveva E3D Design is a haven of multidisciplinary 3D plant modeling, laser scan integration, and clash detection.
Autodesk Plant 3D has spec-driven piping, P&ID‐to-3D consistency, and automated isometric outputs.
CADWorx Plant Professional has huge component libraries, intelligent routing, and interference checking built in.
CAESAR II by Hexagon provides pipe stress and flexibility analysis per ASME and ISO codes, and dynamic load simulation.
OptiPlant (ASD Global) supports auto routing of pipe, tray, and conduit; built-in rule libraries for spacing and clearance.

Three Perks Of Our Pipeline Design

Pipeline projects succeed when designs move smoothly from concept to fabrication. Unlike other gas pipeline engineering companies, our approach blends code-driven engineering, BIM technology, and construction practicality. The result: faster approvals, fewer reworks, and layouts aligned with industry safety standards.

Integrated BIM Coordination

Clash-free layouts ensure seamless fit across structural and mechanical systems.

Verified Stress and Flexibility

Every pipeline design is tested under ASME codes for thermal expansion.

Fabrication-Ready Documentation

Spool drawings and BOMs reduce errors during shop assembly.

How To Order From Our Oil and Gas Piping Designs Firm

Working with us doesn’t mean wading through paperwork or waiting weeks. You contact us, we gather the information, and the design process begins almost immediately. Our method balances simplicity with rigor, so projects stay compliant while moving forward efficiently.

Tell Us What You Need

Send over your project details. It can include P&ID sketch, plant layout, or even rough notes. Our engineers review code requirements, service conditions, and material specs. Within forty-eight hours, you’ll have a scope summary, an estimated timeline, and a cost proposal.

We Draft and Refine

Our design team builds 3D models, spool drawings, and layout files in Plant 3D, Aveva E3D, or CADWorx. Each deliverable undergoes code compliance checks and clash detection. Draft versions are shared quickly, giving you room to suggest changes before approval.

Receive Final Package and Support

Once approved, we deliver native CAD, PDF isometrics, and BIM outputs. A complete bill of materials and tag list is included. After handoff, we remain available for updates, audits, or future retrofits. So, your documentation always reflects reality.

Frequently Asked Question

How fast can I expect drawings or spool packages?

Typical small isometric or spool packages are turned in one to two business days. Larger scopes (compressor stations, long pipeline segments) take longer, with explicit schedules. We always provide milestone dates, interim review files, and a documented delivery plan so fabrication shops can plan manpower and materials.

Can you work directly from laser scans or as-builts?

Yes. We import point clouds into Aveva, Plant 3D, or Revit and extract centerlines, supports, and as-installed geometry. That feeds BIM models and clash reports. For brownfield projects, we deliver accurate as-built drawings and coordinate lists so retrofits, tie-ins, and permits proceed without guesswork.

What file formats will I receive at project completion?

We supply native CAD files (DWG, DGN), neutral exports (STEP, IFC), PDF isometrics, and Excel BOMs with tags and procurement notes. Need a specific format? Tell us. We also provide NWC/NWD exports for Navisworks and IFC for federated BIM coordination on large projects.
