Pipe Lining Process

Our cured-in-place pipe lining repair process is a time-tested and widely-used method for repairing broken, cracked, and failed sanitary sewer pipes. Save the landscaping, driveway or foundation of your business or institution and avoid disturbing the surrounding properties with a muddy mess, detours and loud construction noises for weeks at a time.

With the staggering costs of traditional digging and pipe replacement, the services offered by the Pipe Lining Company, A CIP PIPE, LLC Company make sense for your commercial or industrial property. Why would you choose any other method? Cured in pipe lining can save you and your business money.

The Pipe Lining Company, A CIP PIPE, LLC Company specializes in repairing commercial, industrial and institutional properties pipes that include iron, clay, PVC, Orangeburg, HDPE, ABS, concrete and more.

The Pipe Lining Installation Process

Our pipe lining process uses heated conditioned air to move a non-toxic abrading agent through designated pipe runs and segments. The movement of the agent through the pipe dislodges the corrosion buildup and transports it to an exit opening in the pipe where it is collected in a cyclonic grit unit and dust collection system. The waste corrosion product is non-toxic and easily disposed of without any harm to the environment. The result is a clean, rust-free polished surface inside the pipe.

Following pipe cleaning, a potable water-safe, liquid epoxy is distributed through the piping using heated controlled airflow to facilitate optimal adhesion and curing. The pipe lining will cure within 12-24 hours, after which time the system is reassembled and returned to service the next day. The result is a smooth and durable finish resistant to further corrosion and deterioration.

Step 1: Pipe system diagnosis and set-up

The existing pipe system is inspected for integrity and spot repairs on excessively worn joints and fittings are made where necessary. Valves are removed and their locations temporarily fitted with unions and/or couplings that remain through the restoration sequence. Sitting water is drained from the pipe system and air is introduced into the system to test for leaks. Temporary bypass water piping provisions are installed as necessary.

Step 2: Pipe cleaning

The pipe runs being restored are dried with heated compressed air to remove all moisture. The air medium is then used to distribute an abrading agent throughout the pipe to remove all rust and corrosion products. The removed corrosion material is subsequently gathered into a collection unit. Air is again surged through the pipe to remove any residual debris and dust fines.

Step 3: pipe lining

The cleaned pipe system is re-heated to create an optimal internal pipe surface environment prior to the epoxy coating. An air pressure leak test is again performed prior to coating. Conditioned air is then introduced into the pipe to uniformly distribute the epoxy lining throughout the pipe segment. Following the coating application, continuous controlled air is sent through the piping to facilitate epoxy curing.

Step 4: System re-assembly and evaluation

After the lining is cured, all removed valves and fittings are returned to their original locations. A final leak test and inspection are performed. Water quality, volume, and flow are tested.

Certified and Approved Pipe Lining Materials

Our pipe lining materials are laboratory tested and certified. They exceed specifications and standards set by the American Section of the International Association for Testing Materials (ASTM). They last a minimum of 50 years and are environmentally safe.

The pipeliner materials we use are made from flexible, double-layered felt with one strong coarse fabric reinforcement layer. The tubular liner is sized correctly so it expands and fits tightly within the circumference of the original pipe. The tube’s outside layer is coated with a 2mil thick Polyvinyl Chloride finish.
