Product Application

Advantages of using Resiline

Application characteristics

  • The product is easily pumped and therefore provides a superior application
  • Avoidance of exotherm spike – avoids a rapid high spike in exotherm on initial application and cure.

Lining applications

  • Resiline can be used as a corrosion protection coating for the internal rehabilitation of pipelines irrespective of the material of construction
  • Resiline can be applied to a range of pipe diameters ranging from 3″ (75mm) upwards*
  • Resiline 320 linings from 40 mil (1mm) minimum thickness up to 120mil (3mm) thickness can be applied in a single pass operation**
  • Resiline 320 linings up to a maximum thickness of 9mm may be applied in multiple passes***
  • Resiline 330 linings from 40 mil (1mm) minimum thickness up to 240mil (6mm) thickness can be applied in a single pass operation

Cleaning and Lining Equipment

Resiline recommend the use of Cleaning Equipment and Lining Rigs from Schur-BPH Limited

Application Process

The rehabilitation process begins with a full site evaluation and condition assessment. Specific details addressed during this project planning phase include environmental and regulatory compliance, traffic controls and the strategic location of the access pits. A detailed work schedule is then created to minimise impact on traffic, businesses and homeowners.

Install all traffic, pedestrian and worker safety equipment. Access pits measuring around 1.5 meters x 2.5 meters (5 feet x 8 feet) can be excavated. The pipe is isolated, de-watered and typically a 1.2 meter section of the pipe is cut out and removed.

The can be cleaned using a mechanical cleaning process (rack feed boring, drag scraping, forced air vortex aggregate or high pressure water jetting). This restores the pipe to its original capacity, after cleaning foam swaps may be used to remove loose debris and standing water. Prior to lining a CCTV inspection of the pipe is completed and digitally recorded, service laterals are mapped and inspected to ensure they are clear of debris.

The material is deposited on the inner wall of the pipe using a controlled spin-cast spray lining technique. During lining, a propriety software and hardware system monitors and controls the equipment to ensure proper application in each section of pipe.

Once the installed liner has cured it can be inspected, CCTV inspection completed for each section, including each connection. A detailed lining report is maintained by the applicator and copies of all records are provided to the asset owner or operator. If the pipe has been lined with Resiline 320 (drinking water pipe) then disinfection can take place according to local or country standards after 60 minutes.

Once the return to service procedures are completed the pipe can be reconnected. Equipment is easily demobilised after each lined section and access pits can be filled and paved.
