Predictika · Pre-insulated district heating and cooling piping

An AI sales agent's district piping order, checked before it goes out

An AI sales agent prepares an order for a pre-insulated piping run: the system, service, size, temperature and pressure, jacket and insulation, sections and field joints, and leak detection. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the system and ordering rules and returns a verdict, every reason and the figures it computed.

Scope: Perma-Pipe pre-insulated piping orders: Multi-Therm, Poly-Therm and Chil-Gard systems with PermAlert leak detection for district heating and cooling. See everything this validator covers

This validator models pre-insulated district heating and cooling piping orders, not just the scenarios shown below. Product names and the facts Perma-Pipe publishes are noted in the fine print at the end; all other limits are typical.

  • Systems — Multi-Therm (steel carrier pipe with aerogel insulation inside an insulated steel conduit with an FRP or HDPE jacket, for steam and hot water up to 750 F), Poly-Therm (polyurethane or polyisocyanurate foam with an FRP jacket, up to 250 F, for hot and chilled water) and Chil-Gard (PVC service pipe, polyurethane foam, PVC jacket, for underground chilled and condenser water).
  • Pressure, size and installation — temperature and pressure limits, nominal sizes, section lengths, field joints for each run, two feet of cover and thrust blocks at direction changes for Chil-Gard, and a flow velocity limit.
  • Leak detection and approvals — PermAlert cable that must cover the run, required on steam lines; engineering review for large pipe sizes and for Multi-Therm near its limit; sign-off for very long runs.

Any pre-insulated district heating or cooling piping order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Perma-Pipe piping is engineered to order and quoted per project, so this validator produces no price build-up or line-item quote), fittings and expansion loops, oil and gas pipeline coating, double-containment piping and other Perma-Pipe systems such as Xtru-Therm, PVC-Therm and Galva-Gard. Limits and rules that Perma-Pipe has not published are typical for pre-insulated piping; see the fine print at the end of the page.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A system whose jacket, insulation, service and temperature limit all go togetherOnly with care
Each system needs its own set of product rules. It works, but every new system or option is another set of rules to maintain.		System, service, temperature, jacket and insulation are in one request and every pairing is checked together.
Installation requirements that depend on the system, such as cover, thrust blocks and flow velocityOnly with workarounds
The requirement links the system on one line with quantities on others, so it needs cross-line rules that interact with the rest.		Every choice is in one request, so a missing item is found whichever order the choices arrive in.
Sections, field joints and leak detection cable that must cover the runOnly with care
The needed quantities depend on the run and the section length; each needs its own calculation and comparison.		Required sections, joints and cable are computed on every call and compared with the order.
A stated length that must match the sectionsOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed total, but someone has to write and maintain that comparison.		The stated figure travels with the order and is compared with the computed length on every call.
Large sizes, near-limit temperatures and very long runs that need reviewOnly with workarounds
Approval routing usually lives in a separate workflow, so the quote can leave the rep before the approval is raised.		The verdict says needs approval and gives each reason on the same call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a pre-insulated piping run: the system, service, size, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the system and ordering rules and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Multi-Therm system for a steam line: a 9,000 ft run of 26 inch pipe in 225 sections of 40 ft. The order states that it contains 9,000 ft of piping. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings and one approval, all in one answer. The operating temperature of 780 F is outside what this system handles (Multi-Therm up to 750 F, Poly-Therm up to 250 F, Chil-Gard below 100 F). The jacket on the order is not the one this system is built with (Multi-Therm an FRP or HDPE jacket, Poly-Therm an FRP jacket, Chil-Gard a PVC jacket). The insulation on the order is not the one this system is built with (Multi-Therm aerogel with polyurethane foam, Poly-Therm polyurethane or polyisocyanurate foam, Chil-Gard polyurethane foam). The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings and one approval in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for a system whose jacket, insulation, service and temperature limit all go together, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the operating temperature to 720 F, the nominal size to 24 inches, the jacket to FRP and the insulation to aerogel and polyurethane foam. Two more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The five blocking findings are cleared; two approvals remain for a person: large steel pipe size and temperature near the system limit.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the operating temperature to 650 F and the nominal size to 20 inches.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared, and the validator's figure matches the order.
    18. 
      
  18. Six problems caught in one call, fixed in two passes, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
