Specialised, non-intrusive solutions for uninterrupted food and beverage operations

Allied Pipefreezing - Orange Line

In food and beverage manufacturing, system downtime can compromise more than just production targets. It can impact product quality, safety standards, and regulatory compliance. From processing lines and CIP systems to refrigeration networks and steam supplies, uninterrupted operation is essential for maintaining output and meeting strict hygiene requirements. That’s where Allied Pipefreezing Services (APS) comes in.

 

Our proven pipefreezing methods allow you to isolate and service pressurised systems without the need to drain or shut down entire networks, keeping your food and beverage facility fully operational, compliant, and productive.

Common Challenges in Food & Beverage Facilities

Allied Pipefreezing - Orange Line

Even routine maintenance becomes high risk in food and beverage environments. Key challenges include:

No-Room-for-Error Downtime:

Shutting down systems can halt production lines, compromise batch quality, and disrupt time-sensitive processes like fermentation or pasteurisation.

Hygiene and Contamination Control:

Working around live processing lines demands non-intrusive, sterile methods that protect product integrity and prevent cross-contamination.

Regulatory Compliance:

Every intervention must follow strict food safety regulations whilst maintaining HACCP standards and traceability requirements.

Multi-System Complexity:

CIP systems, process water, steam, and refrigeration networks are interlinked. One interruption can affect entire production cycles and compromise food safety.

Quality Assurance Standards:

Maintenance work must not compromise the facility’s ability to meet quality control protocols or contaminate sterile processing environments.

Testimonials

Allied Pipefreezing - Orange Line

Here are some of the nice things our clients say 
about our services.

We found the service to be invaluable. The time it took to complete the works was substantially less had a traditional shutdown be carried out. The need to continue supply to the critical wards was crucial. Other more traditional methods would not have been able to offer this benefit.

Frequently Asked Questions

Allied Pipefreezing - Orange Line
Is pipe freezing HACCP-compliant for food and beverage production environments?
Yes. Pipe freezing is inherently compatible with HACCP (Hazard Analysis and Critical Control Points) requirements because it is a non-intrusive process. The liquid nitrogen is applied externally to the pipe and never contacts the product inside. No foreign substances are introduced into the pipeline, and no contamination risk is created. The ice plug forms from the existing pipe contents, creating a clean, temporary barrier. APS provides full method statements and risk assessments that align with HACCP protocols, ensuring that all work is documented and traceable for food safety audits. Our engineers are experienced in working within food-grade environments where hygiene, quality, and traceability are non-negotiable.
APS takes a multi-layered approach to contamination prevention in food production environments. First, pipe freezing is a non-intrusive technique — the liquid nitrogen is applied externally and never enters the pipe, so there is zero risk of introducing foreign materials into the product line. Second, our engineers follow strict site protocols including appropriate PPE, hygiene procedures, and food-safe work practices. Third, all work is covered by a detailed method statement and risk assessment that addresses the specific contamination risks of the facility. Finally, all equipment brought on site is clean and inspected. For food and beverage clients, we provide full documentation for compliance records, quality audits, and traceability requirements.
Yes. Pipe freezing is effective on glycol-based cooling systems, which are widely used in breweries, soft drink manufacturing, dairy processing, and wine production. Glycol solutions freeze at lower temperatures than water, so the process requires careful assessment of the glycol concentration to determine the correct freeze parameters. APS engineers assess the glycol mix ratio and pipe conditions as part of the site survey to ensure a reliable ice plug can be formed. We have successfully carried out pipe freezing on glycol systems in brewery and beverage production environments, allowing cooling system maintenance without interrupting fermentation, storage, or production processes.
Yes. One of the primary advantages of pipe freezing is that it allows pipeline maintenance to take place while production continues. The process is quiet, generates no vibration, produces no sparks or flames, and creates no contamination risk — making it suitable for use during live food production shifts. APS frequently carries out pipe freezing in operational food factories, bakeries, meat processing plants, and dairy facilities during active production hours. Where client preference or site conditions require it, we also work during non-production windows including nights, weekends, and scheduled cleaning breaks. All scheduling is agreed in advance with the site production and engineering teams.
Can pipe freezing be used on CIP (clean-in-place) systems?
Yes. Pipe freezing can be used to isolate sections of CIP (clean-in-place) pipework for maintenance, valve replacement, or modifications without taking the entire CIP system offline. This is particularly valuable in food and beverage facilities where CIP circuits are critical for maintaining hygiene standards and production schedules. By freezing a targeted section of the CIP loop, APS allows maintenance to be carried out while the rest of the cleaning system continues to serve other production areas. This avoids the significant downtime and re-validation time that a full CIP system shutdown would require.
Yes. APS carries out hot tapping on refrigeration and chilled water systems in food storage, cold chain, and temperature-controlled processing facilities. Hot tapping allows new connections, valves, or instrumentation points to be added to live refrigeration pipework without interrupting the cooling supply. This is essential in food storage environments where any loss of temperature control can compromise product safety and result in stock losses. Our equipment handles a wide range of pipe sizes and refrigerant mediums including chilled water, glycol, and brine systems. All work is performed by certified APS technicians with appropriate food-environment safety protocols.
APS holds a comprehensive range of accreditations that support work in food and beverage environments. These include: SafeContractor (health and safety compliance), Constructionline (supply chain pre-qualification), CHAS (Contractors Health and Safety Assessment Scheme), ISO 9001:2015 (quality management), Gas Safe Register, and UVDB (utilities sector pre-qualification). Our engineers hold CSCS cards and undergo continuous professional development through a CITB-approved Training Plan. All work is documented with full method statements, risk assessments, and completion reports suitable for food safety audits, HACCP records, and BRC (British Retail Consortium) compliance documentation.
Line stopping is a mechanical isolation method used when pipe freezing is not suitable, typically on larger-diameter mains or systems with high flow rates. The process involves welding or clamping bespoke fittings onto the existing pipeline, installing temporary isolation valves, drilling under pressure (hot tapping) to access the pipe, and then inserting a mechanical stopper to block the flow. A temporary bypass can be installed around the stopped section to maintain supply to other areas of the facility during the work. Once the maintenance is complete, the equipment is removed and the fittings are permanently plugged and capped. APS has used line stopping in food manufacturing facilities — including the Warburtons bakery in Nottinghamshire — to isolate gas mains and process pipework without halting production.
