Engineering & Design

Our professional engineers and designers utilize their sufficient engineering design experiences, expertise, accuracy and excellent industry practices to provide pressure vessel, heat exchanger and tank engineering design and drafting, skid package design and drafting, fitting design and drafting, pressure piping engineering design and drafting, piping stress analysis, FEA and nozzle & clip local stress analysis, ASME certificate application or renewal design to our clients worldwide.

Pressure Vessel, Heat Exchanger and Tank Engineering Design and Drafting

Excel Design Services Inc. utilizes Codeware Compress software or our own flexible Excel calculation spreadsheet to design pressure vessel and heat exchanger as per ASME Sec. VIII Div. 1 & Div. 2, CSA B51, TEMA and client’s design specifications. We use AutoCAD to draft the scaled construction drawings. The regular engineering design process is we submit the engineering design package including design calculations and construction drawings to client for approval after finishing them, and then we submit the design package to Alberta Boilers Safety Association (ABSA) or the safety authorities of other provinces for Canadian Registration Number (CRN) registration after receiving the approval from client. Also, we offer the pressure vessel and heat exchanger re-rate, repair and alteration design calculation and drafting.
We design the above-ground welded storage tank as per API 650, API 620, API 12F and client’s design specifications. In addition, we offer design for shop fabricated steel aboveground tanks as per ULC S601/S602 and steel underground tanks as per ULC S603. Excel Design Services Inc. also provides engineering design services to support tank site repair/alteration including tank bottom, shell, roof and nozzles as per API 653.

Skid Package Design and Drafting

Excel Design Services Inc. custom designs the modular skid packages for oil and gas production, process facilities and water treatment system. It includes 3D model, P&ID, equipment, GA layout, piping and skid by AutoCAD and Solidworks.

Fitting Design and Drafting

Excel Design Services Inc. offers Category A, B, E and H fittings design calculation and scaled drafting by our own flexible Excel calculation spreadsheet and AutoCAD in accordance with ASME Sec. I, Sec. IV, Sec. VIII Div. 1 & Div. 2, B31.1, B31.3, B31.11 and CSA B51. We provide the fitting design services for Canadian Registration Number (CRN) registration with Alberta Boilers Safety Association (ABSA) or the safety authorities of other provinces.

Pressure Piping Engineering Design and Drafting

Excel Design Services Inc. specializes in pressure piping engineering design as per ASME B31.1, B31.3, B31.4 and CSA Z662 including wall thickness calculation, nozzle reinforcement calculation, flange pressure-temperature rating calculation, hydrotest pressure calculation and stress verification, impact test verification, Post Weld Heat Treatment (PWHT) check, material selection diagram, piping isometrics, piping line classes, line designation tables, P & ID specialty items, welding procedure specification (WPS) and NDE matrix. Also, our designers are adept at drafting isometric cut sheet drawings by AcornPipe software for shop fabrication.

Piping Stress Analysis

Excel Design Services Inc. provides piping stress analysis services for our clients. We have wide range of project experience to carry out the full spectrum of stress analysis services. We conduct detailed stress analysis using CAESAR II, AutoPipe and NozzlePro to ensure that the piping system meets ASME, CSA code requirements and client specifications.

FEA and Nozzle & Clip Local Stress Analysis

Excel Design Services Inc. provides Finite Element Analysis (FEA) services to our clients to design pressure vessel, fitting and tank which are not covered by the general rules specified in ASME Sec. VIII Div. 1 & Div. 2, B31.1, B31.3 and API 650. Finite Element Analysis (FEA) is the principal tool that has been used to design and then assess the stresses in the static equipment. The Finite Element geometry is a 3-D model subject to various loads using ANSYS software to do stress assessment as per the load cases and evaluation criteria specified in ASME Sec. VIII Div. 1 and Div. 2. We also offer nozzle or clip local stress analysis due to external loads working on pressure vessel and tank to overcome the limitations of Welding Research Council Bulletins WRC-107 and WRC-297, and to design safer static equipment more efficiently, accurately and cost-effectively. Using this method you can check whether the pressure retaining components with nozzle or clip can withstand the external loads specified or required to be modified.

ASME Certificate Application or Renewal Design

Excel Design Services Inc. design Demonstration Vessel or Pipe Spool to our clients as per the latest edition ASME Sec. I, Sec. VIII Div. 1 & Div. 2, B31.1 and B31.3 for ASME certification application or renewal audit to acquire ASME “U”, “PP”, “A”, “S” stamps and National Board "NB", "R" stamps. The design package includes Compress software calculation, Excel spreadsheet longhand calculation to verify the accuracy of Compress software calculation, scaled construction drawing drafted by AutoCAD, heat number drawing, NDE and weld map drawing. We also provide Certificate of Authorization Permit application or renewal design with Alberta Boilers Safety Association (ABSA) or the safety authorities of other provinces.
