Ultraliner PVC Alloy Pipeliner
The Products section of our website provides information regarding the material properties, available dimensions, installation process, installation equipment, as well as the manufacturing process pertaining to Ultraliner PVC Alloy Pipeliners. Hydroliner is the only company to provide both ASTM F 1871 and F 1504 industry standard pipeliners. We encourage you to consider the differences between Ultraliner PVC Alloy Pipeliner's Higher Compliance [complying with ASTM F 1871] and Higher Stiffness [complying with ASTM F 1504]. Hydroliner is also the only company which regularly supplies fold and form PVC pipeliners in diameters from 4" up to 30".
For a general description of how our products work and what they help you to accomplish, continue reading below. You can find the most widely used submittal documents here. For concise answers to specific questions, we encourage you to search Ultraliner's Frequently Asked Questions [FAQ]. We also invite you to study "The Strengths of Ultraliner" to develop a greater understanding of the advantages of using Ultraliner's PVC Alloy pipeliners.

Product Overview - What a difference a PVC Alloy makes!
Ultraliner PVC Alloy Pipeliner is the perfect pipeline rehabilitation solutions for gravity and low pressure wastewater or storm sewers and culverts.
PVC Alloy is a term used to describe Ultraliner's uniquely enhanced PVC material which has been specifically engineered for use in trenchless applications. Not only does the Ultraliner PVC Alloy have sufficient material stiffness to provide full, independent structural integrity, but it also has extremely high impact strength, enables a high degree of dimensional stability, and can relieve high levels of stress without structurally compromising the material. The Ultraliner PVC Alloy material is an extremely "tough" material in the truest sense of the word.
The PVC Alloy material can be "thermoformed" at steam temperatures, enabling Ultraliner PVC Alloy Pipeliner to essentially "blow-mold" to the conformation of the host pipe. Upon "blow-molding," Ultraliner PVC Alloy Pipeliner will conform almost exactly to the shape of an existing pipeline, including size transitions, tight bends, offset joints, and other irregularities. Ultraliner PVC Alloy Pipeliner will even conform tightly to the shape of corrugated pipe.
In addition to its strength, flexibility, ductility, and tight fit, Ultraliner PVC Alloy Pipeliner is extremely resistant to chemicals and abrasion. In fact, years of laboratory tests and experience in actual installations indicate our product will not degrade in a typical sewer environment.
NO POST-INSTALLATION SHRINKAGE
An important characteristic of Ultraliner PVC Alloy Pipeliner is that, due to Ultraliner's unique material and installation process, there is no significant shrinkage, neither radially nor longitudinally, after it has been installed. Therefore, it maintains its tight fit (and its ability to control groundwater migration) for the design life of the material.
Ordinary thermoplastics have a "memory" of their original, manufactured size and shape. If that memory is not altered or disrupted, thermoplastic pipes have a tendency to shrink back towards their original size and shape after they have been expanded.
However, Ultraliner's unique PVC Alloy compound and our special installation procedure allow the "memory" of Ultraliner PVC Alloy Pipeliner to be reset to the new, expanded shape and size. As a result, once an Ultraliner PVC Alloy Pipeliner has been properly installed, it will not shrink away from the host pipe.
FACTORY MANUFACTURING ASSURES CONSISTENT QUALITY
Ultraliner PVC Alloy Pipeliner is manufactured in a highly controlled environment.
When you specify Ultraliner PVC Alloy Pipeliner, you will always get the same high-quality product. Since the pipeliner is manufactured in a tightly controlled factory environment, you are assured that every foot of your new pipeliner will meet your specifications and all applicable industry standards. In fact, the only variations from one Ultraliner installation to the next are the ones you specify.
Prior to insertion, Ultraliner PVC Alloy Pipeliner is shaped into a reduced form to assist in installation.
Once pulled through the pipeline, it is expanded tightly against the host pipe.
4" to 12" Ultraliner PVC Alloy Pipeliner is coiled in a flat shape and folded during insertion; whereas 15" and larger Ultraliner PVC Alloy Pipeliner is coiled in an "H" shape.
CAREFULLY CONTROLLED INSTALLATION ASSURES PERMANENT FIT
The profile of Ultraliner PVC Alloy Pipeliner is folded in the field with small diameter pipeliners (12" or smaller) and may be deflected to a smaller circumference at the factory during the manufacturing process with the "bulkier" large diameter pipeliners (larger than 12"). This reduces the cross-sectional area of the pipe by almost half without disrupting the ability to effectively "blow mold" the pipeliner into its new memory configuration.
The reduced size, the high abrasion resistance, and the very slick surface allow Ultraliner PVC Alloy Pipeliner to be pulled into a pipeline through an existing access point, such as a manhole, without trauma to either the Ultraliner PVC Alloy Pipeliner or the host pipe. Because the pipeliner is pulled along the invert without contacting the crown of the pipe, Ultraliner PVC Alloy Pipeliner is routinely used to line extremely crushed pipe with minimal risk of generating a collapse.
Normally, Ultraliner PVC Alloy Pipeliner is installed in sections of about 300 feet --- from one manhole to the next --- although installations of 8" and 10" pipeliners exceeding 1,000 continuous feet and installations of 21" and 24" pipeliners exceeding 500 continuous feet have been successfully accomplished. Typical installations only require four to five hours to pull and process the pipeliner, with additional time required to fully reinstate the service connections. Short lengths of culvert pipe, which lack service connections, are often completed in two to three hours.
Once inserted, the pipeliner is heated sufficiently to allow the material to "relax" and to reset the PVC Alloy's "memory" to the new size and shape it has assumed. As a result, the installed Ultraliner PVC Alloy Pipeliner will not attempt to return to its original size or shape after it has cooled, nor will it longitudinally shrink.
Ultraliner PVC Alloy Pipeliner's tight fit against the irregular shape of the host pipe mechanically locks the pipeliner in place throughout its service life and thereby controls the leakage of groundwater between the host pipe and the pipeliner.
After the pipeliner has properly cooled, pressure is relieved and the ends are trimmed at least 3 inches from the manhole walls. Lateral service lines are located and reopened using remote-controlled devices. The unique Ultraliner PVC Alloy material is more ductile (less brittle) and relieves stresses more readily than typical PVC compounds, thereby avoiding cracking or shattering of the pipeliner when the services are reestablished.
THE ULTRALINER INSTALLATION PROCESS
Ultraliner PVC Alloy Pipeliner is pulled into a prepared host pipe.
The Ultraliner PVC Alloy Pipeliner is plugged and expanded with steam and air pressure.
The Ultraliner PVC Alloy Pipeliner forms a permanent, tight-fitting new pipe.
Because Ultraliner can be installed quickly through existing access points, there is very little or no disruption to the community. Most residents are amazed when they later learn that construction took place and the pipes have been renewed.
The original pipeline will be sealed, thereby controlling infiltration, exfiltration, and root intrusion, with a jointless, smooth pipeliner which will not degrade.
The pipe (or the existing "hole in the ground") will have a renewed service life expected to exceed 50 years.
