Process and Extraction Piping Contractor in Colorado

Yes, across the Front Range and statewide: pressurized extraction systems, solvent and gas handling, sanitary process lines for beverage and food production, and utilities. We self-perform fabrication and welding, and we supply material certification, weld logs and qualification records as a matter of course rather than on request.

Because the service is flammable solvent or high-pressure carbon dioxide in an occupied building, so a pressure-containing failure is a safety event rather than a product loss. Equipment sold without material certification may be entirely sound, and the problem is that nobody can demonstrate it when an authority having jurisdiction, an insurer or a buyer conducting due diligence asks.

Start with the two things that can be recovered. Pressure testing can be repeated, and relief device sizing can be recalculated and verified against the system as it actually exists rather than against an assumption inherited from the supplier. That calculation is the most valuable single check available on an inherited skid. Material certification and weld records cannot be recreated, so components of unknown provenance in critical service are usually replaced.

At tender rather than after award: ASME Section IX welder qualifications, the welding procedure specifications and supporting qualification records, current for the material and configuration, plus a commitment to material certification with heat number traceability and a weld log tied to an isometric. A fabricator who can produce those at tender has them.

ASME B31.3 covers process piping, and the fluid service category determines how demanding the design, examination and testing requirements are. That determination should be made before fabrication, because examination not performed at the time cannot be created retrospectively. The piping code sits alongside, not instead of, the electrical area classification for the space.

Everything electrical within the classified space: motors, instruments, junction boxes, lighting and the control panel. It lands on the piping scope because transmitters and actuated valves mount on the pipe, so instrument selection has to be coordinated with the classification before procurement rather than discovered at commissioning when a device cannot be installed where the pipe needs it.

Because the classification frequently assumes a ventilation performance, and that assumption sits on a drawing nobody revisits. If ventilation was later reduced, obstructed by a layout change, or never achieved the assumed rate, the classification the electrical equipment was selected against no longer describes the room. Confirming the assumed rate and measuring the actual one is modest work and unusually worthwhile.

The piping code does, and the area classification question appears wherever flammable vapor is present, which includes a stillhouse. What differs is scale and pressure: extraction systems commonly operate at pressures well above anything in a brewery, which raises the consequence of a component of unknown rating and makes provenance more important rather than less.

Very little. At 8.62 cents per kilowatt-hour against a national average of 8.13 (EIA, 2024), Colorado is slightly above the midpoint, so insulation and heat recovery decisions follow process and safety requirements rather than tariff. On extraction systems the economics are dominated by throughput and by the cost of an unplanned shutdown, not by utilities.

Use the form on this page or call 201-450-8280. Useful inputs are what the system handles and at what pressure, whether any existing equipment lacks documentation, whether the space is classified and against what assumed ventilation, line sizes and approximate footage, and whether this is new build or modification. If you have an inherited skid, say so, because that changes where we start.

With vapour lines sized for the evaporator's rate and sloped to the condenser, condensate returned to solvent storage through closed lines, and the whole loop vented only through the emission control the permit requires. Recovery efficiency is a piping and condenser design outcome, and it determines solvent cost and emissions together.

Hydrocarbon systems run at pressure with butane or propane and need pressure-rated piping, relief and leak detection throughout; ethanol systems run at low pressure and often very cold, so their piping is designed for low-temperature embrittlement and condensation rather than pressure. The area classification applies to both, for different reasons.

Materials that stay ductile at the chiller's temperatures, insulation with a vapour barrier so that the lines do not ice and drip, and expansion provision for the contraction between ambient and operating temperature. Cold ethanol lines built with ambient-temperature details ice, leak and crack.

With short, large-bore lines to the vacuum pump, traps to catch solvent and product carryover before the pump, and joints that hold vacuum without leaking air into the process. Vacuum leaks slow evaporation and pull air into a solvent system, which is both a process and a safety problem.

Detectors at low level where solvent vapour collects, set to alarm and to increase ventilation at a fraction of the lower explosive limit and to shut down the process at a higher fraction, with the interlocks tested on a schedule. Detection without interlocks tells people about a hazard it did nothing to control.

Solvent boiling points and vapour pressures are altitude-sensitive, so recovery and evaporation steps operate at different conditions than at sea level, and pressure relief calculations use local atmospheric pressure. Procedures written elsewhere are checked for altitude.

ASME Section IX welder and procedure qualification, with weld records kept, and visual and where required radiographic inspection under B31.3. Sanitary orbital welding to ASME BPE applies where the product-contact side is hygienic.

Glycol lines insulated and traced where they can freeze, carbon dioxide lines rated for the pressure at the lowest ambient and vented safely, and outdoor equipment winterised before the first freeze. Front Range temperature swings can move a line from summer expansion to winter freeze within a week.

Relief devices sized for the credible overpressure cases, set within the equipment's rating, discharging to a safe location, and documented. Missing or undocumented relief is a common survey finding on inherited equipment.

By pressure or vacuum testing to the code's requirements before solvent is introduced, with the test recorded. Leak testing with solvent in the system is not a test; it is an incident.

High-pressure carbon dioxide is not flammable but operates at very high pressure, and its piping and vessels are designed and documented to the codes for that pressure. The documentation requirement is the same; the hazard is different.

Colorado's wide temperature swings move outdoor stainless runs materially, and expansion provision and support design account for it. Rooftop and yard piping on Front Range sites is designed with the range.

With material records, weld records and drawings for product-contact lines, and with the CIP circuit design recorded so that cleaning validation references it. Colorado's brewing sector has a great deal of undocumented piping from rapid expansion.

Insurers and fire authorities increasingly require documented equipment, classified areas and engineered ventilation, and a facility without them may not be insurable or permitted. Documentation is a licence to operate.

By purging solvent from the system, disconnecting under permit with the area's classification observed, documenting the system's condition, and re-verifying it at the new site as if it were newly installed. Extraction skids move between Colorado operators often, and the move is where their history is lost.
