To help inform our tank and vessel customers about jacketed vessels and heat exchange surfaces, Apache shares this e-book that in-house specialists produced, "Abstract and Attributes of ASME Vessel Heat Transfer Surfaces".
Jacketed vessels are used in many industries and can remove the elevated heat of reaction (heat reactor vessel) or reduce the viscosity of high viscous fluids. There are basically three types of external jacketed heat transfer surfaces: conventional jacket, half pipe jacket and dimple jacket, which are welded to the outside of the vessel. Internal coils can also be used as a stand alone option or in combination with other types of external jackets.

CRN is a Canadian Registration Number issued by each province or territory of Canada for the design and manufacture of boilers, pressure vessels and fittings to be shipped for use in Canada. It is important to note that each province and territories have unique application criteria for CRN.
Some fittings, piping and components are pre-approved for CRN, while others will require detailed calculations and/or testing to verify compliance. Certain design attributes may be accepted by some provinces or territories, but not by others. Further, some provinces and territories require a PE (Professional Engineer) stamp, but not all have this requirement.
One process is consistent; each province and territory requires the submission of the design to the CRN regulatory agency and the equipment must have a CRN number before it can ship and be placed in service.
How can manufacturers and processors plan for CRN for their tank and vessel projects? Start wth early planning and consider vessels as a long lead item. Determine design and shipping requirements at the onset of scope management discussions and allow several weeks, depending on project complexity, for the CRN number to be granted.
Apache provides CRN support on new projects as well as on used vessels orginally used in domestic markets that the customer desires to place into service in Canada.
Having exported to Canada for over 40 years, Apache's small vessel and large tank team have extensive experience with Canadian regulatory requirements and documentation. Apache has produced CRN vessels for many industries including oil, gas, energy, pharmaceutical, cannabis processing, health and beauty, and food and beverage. Apache has provided design, review and registration services for a variety of tank and vessel applications including extraction, evaporation, thermal processing, mixing and batching.
The National Board of Boiler and Pressure Vessels requires a Certificate of Authorization and R-Stamp for the repair or alteration of boilers, pressure vessels and other pressure retaining equipment.
Any repairs to the ASME pressure zones on tanks require an R-Stamp. Any repairs not in that designated area will not require an R-Stamp.
Apache's Field Service Technicians are fully certified ASME welders. For over 40 years, Apache continues to maintain rounds of audits and inspections from ASME compliance and safety professionals that speak to the consistency of the welders and the effectiveness of the quality control department.
Our Field Service team are R-Stamp certified. Apache will also provide all compliance addendum documentation required for ASME repairs of modifications in the field.
A host of modifications are available to ASME and non-ASME tanks and vessels. We offer a feasibility audit to compare field modifications to the cost of a new system.

Sometimes things just happen, like a tool accidentally falling into the tank and causing damage. The damage might be a bent agitator or it might be damage to a side wall or baffles. We see these kinds of things all the time and we can fix them most of the time.
