This paper expounds the development status of composite insulating pipe in the heating and chemical fields from the aspects of materials, structure and application. Combined with the relevant standards and technical requirements, the performance advantages and the key evaluation methods such as axial shear strength, insulation layer performance of composite insulating pipes are discussed.
In order to mitigate climate change, recent trends in building design include a lowcarbon emission approach, coupled with energy-saving initiatives. For the plastic pipe industry it is imperative to improve the heat transfer efficiency of the pipe network. Composite insulating plastic pipe has the advantage of corrosion resistance, low thermal conductivity and reliable connections. The application of composite insulating plastic plays an important role in the new and existing heating pipe networks, chemical transport, apartments and central air conditioning.
There are many types of composite insulating plastic pipes. Various plastic pipes are employed e.g., the service pipe could be PE-RT, PP-R, PEX-b or PVC. According to the different structure, it can be divided into the traditional three-layer composite structure and the new fiber reinforced flexible composite structure. According to the different forms of bonding, there are bonded pipe systems and non-bonded pipe systems.
This paper expounds the development status of composite insulating pipe in the heating and chemical fields from the aspects of materials, structure and application. Combined with the relevant standards and technical requirements, the performance advantages and the key evaluation methods such as axial shear strength, insulation layer performance of composite insulating pipes are discussed.

HDPE Pipe holds a dominant position in several markets in North America: natural gas distribution, oil patch, mining, landfill and geothermal. So why are polyethylene’s municipal water and wastewater market shares so much lower than these other industries? How has the polyethylene industry been successful in growing...

PP-R (random copolymerized polypropylene) has been widely used in hot and cold water systems. However, the standard PP-R pipes have the disadvantages of a large high-temperature thermal expansion coefficient, an insufficient notched impact strength, and a low temperature and pressure resistance. In this paper, a new...

HDPE pipe can be relatively easily scratched during the manipulation on the site, which is especially true for the marine pipelines. Installing the scratched marine pipe with the S bend method presents a risk and repair methods are usually performed. Currently, there is no standard defining the repair procedure, in...

For controlled water disinfection, typically chlorine is used and preliminary studies demonstrate its aging and crack growth acceleration effects on polyolefin pipe materials [1, 2]. Although the use of recycled plastics is not prohibited in some ISO standards for polyolefin piping systems [3–5], only small amounts...

For PE 100-RC, two tests are still under development for pipes: the point load test (PLT) and the accelerated notch pipe test (aNPT). The PLT was developed by a project group consisting of manufacturers and end users. The PLT determines the resistance to point loads as they can occur in practice. An earlier study...

The Point Load Test (PLT) [ 1, 2] was designed to simulate the SCG (slow crack growth) failure initiated by a rock pressing into the exterior wall of a polymer pipe. Today’s PE materials sustain long PLT testing times, due to its high SCG resistance design. Consequently, an accelerated “PLT+” with the support of...

Flowable fill is used for many applications, but mainly for pipe trench embedment and backfill. There are three ways that using flowable fill can be kind to the environment. Because flowable fill is self-leveling and has a strength greater than the native soil, the trench cross section can be minimized. This means...
