Pressure Equipment Design
From start to completion, your pressure vessel design and verification will be handled in the most professional manner by CDMS Consulting Engineers (CDMS). We have 30 years’ worth of experience in dealing with pressure equipment ranging from pressure vessel design to heat exchanger design.
Starting with you initial enquiry, CDMS will guide you through the requirements of your job or project. We will always involve you in the decision making process with clear and concise job proposals at every stage of your project. We value regular communication with you and provide you with written project status reports to ensure you are fully briefed on the progress of your project.
Pressure Vessel Design
CDMS is renowned for its high quality and accurate pressure vessel design and design verification work. They provide services to local, national and international clients, owners, owner-operators, fabricators and consultants, all in strict accordance with our ISO 9001:2015 accredited Quality System.
CDMS undertakes design and calculations of pressure vessels in compliance with Australian Standard AS 1210 and other International Standards like ASME VIII Division 1 and 2 and BS PD5500. CDMS also has capability for Design by Analysis according to ASME VIII Div. 2 Part 5, using both linear and non-linear stress analysis. We have the in-house capability to design and shop detail the full spectrum of vessels for all operating temperatures, pressures and environmental conditions including offshore and on-ship.
Our company has a wealth of experience with the fabrication, lifting, transportation and installation of vessels and can provide relevant studies, calculations and methodology documents as required. Please refer to our page on specialist services for more information on third party verification, fitness-for-service assessments, re-rating of existing vessels and advanced Finite Element Analysis.
Heat Exchanger Design
In addition to pressure vessels, CDMS is experienced in the structural and mechanical design, material specification and design verification of shell-and-tube heat exchangers including floating head and U-tube exchangers, plate exchangers and air-cooled condensers for heating and cooling of liquids and gases in industrial, oil & gas and mining applications. CDMS undertakes mechanical design of heat exchangers in compliance with Australian Standard AS 1210, TEMA and part UHX of ASME VIII Div. 1 for shell and tube heat exchangers. We also have experience in the design verification of plate heat exchangers to AS1210 and ASME VIII-1, as well as Air Cooled Heat Exchangers (ACHE) to API 660. Design of waste heat recovery coils and headers typically involve a combination of piping and vessel design standards, along with design and compliance to API 530 and API 560, both of which CDMS has routinely performed verifications. We have the in-house capability to design and shop detail the full spectrum of heat exchangers for all operating temperatures, pressures and configurations.
High Pressure Equipment
CDMS has experience in designing very high pressure equipment, up to 70 MPa design pressure with 1.3m internal diameter, which requires special consideration in material selection and fabrication process. Due to thicknesses required at these pressures, welding can be prohibitive and whole forgings are used where possible. Where welding is required, special weld procedures and material specifications are required to prevent cracking in the welds. Special consideration must be paid to deformation and flanged joints design in specifying of the appropriate gasket type to avoid leakage. CDMS also has experience in designing high pressure threaded connections.
CDMS is ISO 9001:2015 certified in compliance with AS 3920.1 to provide services for the verification of pressure equipment. Design verification is required as part of design registration process with the Statutory Authorities in all states and territories where the equipment is to be operated.
CDMS can also assist with managing the process of design verification and registration with the applicable Statutory Authority, to provide operators with plant that is ready for install and item registration (where required). Where older designs are found to be unregistered or non-compliant, CDMS can assist with retrospective design, verification, and the successful registration of equipment.
