  • Ease of Use: A relatively short learning curve for existing AutoCAD users.
  • Piping Specifications: Comes with extensive libraries and tools for creating and managing piping specifications.
  • Affordability: Often considered a more cost-effective solution compared to some of the larger, more complex suites.
  • P&ID and Isometrics: Strong capabilities for generating intelligent P&IDs and automatic isometric drawings.

Best Suited For:

  • Small to medium-sized engineering firms or departments.
  • Companies that value AutoCAD proficiency and seek to extend it into 3D plant design without a steep learning curve.
  • Projects where a balance of functionality, ease of use, and cost-effectiveness is key.

Making Your Choice: A Strategic Decision

Each of these software powerhouses brings unique strengths to the table.

  • SmartPlant3D offers an all-encompassing, integrated ecosystem for the entire plant lifecycle, ideal for large, complex, multidisciplinary projects.
  • PDMS (AVEVA E3D) excels at highly detailed 3D modeling and clash detection, making it ideal for precision engineering and construction.
  • CADworx provides a powerful, AutoCAD-integrated solution that offers robust functionality, a familiar interface, and often a more accessible price point.

The “best” software isn’t universal; it’s the one that best fits your project scope, your team’s existing skill set, your budget, and your long-term strategic goals. Consider the scale of your projects, the level of integration required, your budget constraints, and your team’s learning curve when making this crucial decision.

Integrate Design with Real-World Performance: Choose Piping Technology

Choosing the right design software provides the blueprint, but bringing that blueprint to life requires the right components and expertise. Regardless of whether your team employs the integrated power of SmartPlant3D, the detailed precision of AVEVA E3D (PDMS), or the familiarity of CADworx, the real-world performance of your plant hinges on not just design excellence but system reliability.

Furnace Applications – Spring Supports, Expansion Joints & Furnace Seal Bags

December 6, 2022

Ptp furnace application products

An industrial furnace, also known as a direct heater or a direct-fired heater, is a device used to provide heat for an industrial process. Furnace designs vary as to their function, heating duty, type of fuel, and method of introducing combustion air. Heat is generated by an industrial furnace by mixing fuel with air or oxygen, or from electrical energy. The residual heat will exit the furnace as flue gas. Types of industrial furnaces include batch ovens, vacuum furnaces, and solar furnaces. Industrial furnaces are used in applications such as chemical reactions, cremation, oil refining, glasswork, metallurgy, mechanical engineering, chemicals, ceramic, and building materials. Industrial furnaces using fossil fuels are characterized by heat losses from flue gases with a temperature of 500°C and above.

PT&P supplies many products that are well-suited for furnace applications. The first category we’ll take a look at is engineered spring supports. We size furnace springs the same way as we would for a conventional variable or constant spring support. Construction may include a welded design instead of bolted and custom nameplates with the test data and ID tag. Most furnace spring supports are coated with red oxide primer to avoid potential hazards when exposed to high temperatures.

Ptp furnace application variables in service combined

PT&P specially designed and fabricated hundreds of altered Type-A variable spring hangers in order to accommodate the special travel and spring rate needed to support the furnace tubes of a hydrogen reformer in Venezuela. To accommodate customer-specified travel and spring rates, modified spring coils were required. With a travel of 8-7/8″, the variable spring hanger casing lengths were increased from the standard size of 32″ to over 6′ long. The calculated spring rate is 79 lb/sq in for an operating load of 2,804 lb. and an installed load of 3,505 lb. The housings are coated with heat-resistant paint, which protects the spring coils from corrosion and high temperatures in the furnace area.

Expansion joints are not installed inside furnaces due to the extremely high temperatures of the environment and the piping system. Expansion joints will typically be found on the ductwork and in the piping coming in and out of the furnace. In the last six months, we have shipped over 40% of our expansion joint jobs in less than 2 weeks to meet customer project deliverables.
Fabric expansion joint application

Fabric expansion joints that are in-service near furnaces, typically include a 3-layer belt consisting of silicone, fiberglass, PTFE, and mineral wool insulation. The configurations are either round, rectangular or square as seen in the examples below.

Furnace bags are used to seal high-temperature tubes that penetrate the furnace floor. The furnace bag consists of multiple layers of flexible, flame and heat-resistant, impervious fabric designed to operate from start-up to high-temperature design conditions. The bag will expand and contract with the varying furnace temperatures.

Furnace Bag

Stainless steel clamps or band straps connect one end of the pipe that goes through the penetration opening and the other to another sleeve in the furnace floor. A tapered steel coil is installed around the conduit inside the bag to prevent the fabric from collapsing inward during vacuum conditions. PT&P’s standard furnace seal bag is nickel reinforced, with a special coating that reduces airborne fibers and increases tensile strength.
