History of Pipe Lining

Pipe lining is a non-invasive pipe rehabilitation process that can be completed without excavation or demolition of property. It is a time
and money saving option for the rehabilitation of multiple types of existing pipe systems. Flow-Liner® would like to give you a general
history of when pipe lining began and how it is being utilized today.
Pipe lining has been performed in the US since the early 1970's. The technology arrived from Europe and was mainly used for large diameter sanitary
and storm underground drainage piping in municipal infrastructures. Some of the actual equipment first used in pipe lining was patented in the early
1950's. The technology was known to only a few engineering firms and contractors, therefore it was not available to everyone. The technology became
more and more popular after standards and specifications were adopted and engineering firms accepted the option of lining existing underground drainage piping.
It wasn't until the late 1990's that pipe lining became available to the general public. Pipe lining technology, in the same way most technologies evolve,
went from being only capable of lining large diameter pipes to being capable of lining small diameter pipes. This opened the door to many applications and
the market grew into residential homes and commercial building piping systems.
Now almost 40 years later and well into the 21st century, pipe lining is the main stream acceptable alternative to replacement piping. Quality standards
are in place, including engineer testing for a life expectancy of fifty plus years for liners. The technology has also evolved into multiple applications
and industries. These include potable water services, cooling systems, hot water piping, swimming pool and fountain pipes, process piping, mechanical
piping as well as electrical & telecommunication conduit. This technology now allows pipes and conduits as small as ½ inch in diameter to be lined.
As with other non-invasive specialty technologies, lining requires a trained and certified installer in order to perform a professional lining
project. Flow-Liner® prides itself with being capable of providing the necessary training, equipment, support and experience needed
for the lining industry. This includes robotic cutters, pipe cameras, special preparation cleaning equipment, as well as a variety of liners
and resins for a multitude of applications. Flow-Liner® is constantly researching and developing new products, systems and equipment
for our installers' needs as well as developing lining systems for other industry and utility markets.
Municipal officials, facility maintenance personnel, mechanical, plumbing and electrical contractors and building maintenance engineers
around the world are utilizing these technologies. Pipe and conduit lining will keep growing in demand and will become one of the world's largest industries.
