5 Quick Steps for Installing CPVC Pipes

When installing a CPVC pipe system, there are a few different options you can choose from to join the piping and fittings. The pipes can be threaded or flanged together according to their size, each offering a strong and durable union. However, for most applications, solvent cement welding is the recommended process to use.

It does not include using glue. Instead, it is a quick and easy installation process that uses resin and solvents to chemically bond the pipes and fittings together at a molecular level, creating just one piece of continuous plastic.

To ensure that you don’t face any challenges while trying to use the solvent cement welding process, we have listed 5 easy steps to guide you through the process.

  1. Cutting, Chamfering, and Deburring CPVC

> Use tools designed for use with plastic pipes and fittings: Preferred plastic cutting tools include a ratchet cutter, wheel-type plastic tubing cutter, a power saw, or a fine-toothed saw.

> Ensure a square cut on the CPVC pipe using a miter box: Cutting the pipe as squarely as possible provides the maximum bonding surface area. The more surface area that becomes chemically bonded, the more strength the joint will exhibit.

> Do not use a dull blade or a broken cutting tool to cut the pipes

> The burrs and filings present should be removed: Burrs and filings can prevent proper contact between the pipe and fitting and may put undue stress on the pipe and fitting assembly. Use a chamfering tool or file to remove burrs and filings from the outside and inside of the pipe.

> A slight bevel should be placed at the end of the pipe: A slight bevel eases the entry of the pipe into the socket and minimizes the chance of wiping solvent cement from the fitting. For pipe sizes 2 in. and larger, a 10 to 15° chamfer of 3/32 in. is recommended.

2. Preparing the Fitting for Solvent Cement.

Wipe any loose soil and moisture from the fitting socket and the pipe end with a clean, dry rag: Loose soil and/or moisture can slow cure times and reduce the joint strength. Make sure the fit is good by checking that the pipe enters the fitting socket easily 1/3 to 2/3 of the depth.

3. Primer application

A primer is needed to prepare the bonding area for the addition of cement and subsequent assembly. Use a proper applicator, such as a dauber, swab, or paintbrush, approximately half the size of the pipe diameter.

Apply the primer to the inside of the fitting socket and the outside of the pipe end. Apply a second primer coating inside the fitting socket. Re-dip the applicator as often as necessary to ensure the entire surface of both pieces is tacky.

4. Application of Solvent Cement

> Apply solvent cement when the pipe surface is tacky (not wet) from the primer. The joining surfaces must be penetrated and softened.

> Cement should be applied with a natural bristle brush or swab half the size of the pipe diameter. For pipe sizes smaller than 2 in., a dauber may be used.

> Apply a heavy, even coat of cement to the outside of the pipe end, and a medium coat to the inside of the fitting socket. For pipe sizes greater than 2 in., apply a second coat of cement on the pipe end.

5. Assembly

> After cement application, immediately insert the pipe into the fitting socket while rotating a 1/8 to 1/2 turn until the fitting stop is reached. At this time, the fitting should be properly aligned for installation.

> The pipe must meet the bottom of the fitting socket. Once in place, the assembly should be held in place for 10 to 30 seconds to ensure initial bonding and to avoid push out.

> Check that a bead of cement is evident around the pipe and fitting juncture. Wipe off any excess solvent cement with a rag.

> Use equipment for the joining of a large diameter pipe. Kasta pipes are always made of high quality materials are long lasting and stands up to expectation of its buyer. They are made to last the test of time and endure the testing environment. Kasta pipes are always easy to install and easy to maintain.

Importance of Using Fiber duct Pipes in Telecommunication Fitting

HDPE (High Density Polyethylene) PLB (Permanently Lubricated) DUCT PIPE also commonly known as fiber duct pipe is a perfect laying system for telecommunications. These pipes are high flow capacity ducts that are highly suitable options for underground laying of optical fibers cables (OFC). These fiber duct pipes are used for laying and protecting the optical fiber cable underground and work as a conduit for the optical cables. These pipes or ducts are manufactured with very high-density Polyethylene materials, which offers very high resistance against loads under the earth’s surface and so tough that it is impact and crush resistant, keeping the delicate and very sensitive cables inside heavily protected and safe.
These pipes are manufactured in various colors and sizes like red, blue, green, orange, brown and gray that are the most commonly used colors in the manufacturing of the PLB ducts. These pipes are also manufactured in various sizes according to their usage and demand. These pipes may also be tailor-made according to the requirements of the client which is quite a good flexibility given to the clients.

The HDPE PLB Duct pipe or the fiber duct pipe has its advantages which will enable the pipes to go on in the market for a long time. Let us look into some advantages by taking these pipes into use:

1.  Availability of these pipes in various sizes and colors gives the client a good variety to choose from according to his needs and demands.
2.  The pipe offers excellent flexibility too.
3. The impact strength and its capacity to bear a lot of brunts, has made it the favorite with likes of telecommunication sector for underground laying of delicate optical fibers.
4. Due to varied applications of the pipe in varied fields of telecommunication and data handling the future of this type of pipe seems bright as the world is today dependent on data and communication. The toughness of this pipe outside and the smoothness inside makes it the perfect pipe for housing sensitive wire and delicate cables used for modern-day data transfer and telecommunications.

Let us also look into the inherent characteristics of the pipe which makes it so suitable for delicate handling that too under loads of earth pressure. The quality of these pipes has made them stand out in the sectors of telecommunication and data transfer, where wires and cables carry information that is important for daily routine life as well as high-end scientific researches.

1. ESCR (Environmental Stress Crack Resistance) is quite a prominent advantage of using these pipes.
2. Resistance to impact is of great importance as these pipes are mostly used to lay underground cable and wire layouts by serving as a conduit for the delicate and sensitive cables and wires.
3. Highly resistant to sudden impact with heavy loads and will not crush easily. This is also of immense importance as sudden loads on the surface of the earth could put a lot of load on the pipe suddenly and cause it to be crushed.
4. The smooth finish inside with very low coefficient of frictions which is eminent in its type PLB (permanently lubricated) for easy insertion of wires and cable through them for long distances under the earth. This quality is very important as the frictionless character helps the installers to get a larger area of laying covered in a shorter time.
5. The type of wire and cables a Fiber Duct Pipe is supposed to carry may be highly sensitive, fragile and delicate so the pipe itself needs to be highly sturdy and resistant to most of the environmental conditions. Temperature is one such external factor that can affect the things inside the pipe so it is of great value that the Fiber duct pipe is very temperature resistant.
6. The product is made with high-quality materials and with a process that helps it to resist cracking in most conditions.
7. The light-weight nature of the pipes gives another advantage to it in ease of handling along with its lubricant surfaces.
8. With its resistance to chemically react with water it can be easily cleaned with water.
9. UV protection of high level for the material the conduit is carrying.

The above-mentioned inherent qualities of a Fiber duct pipe make it the most suitable conduit in the underground laying of wires and cables may it be just under a sidewalk or between cities.

In short, the PLB FIBER DUCT, a pre-lubricated, robust, lightweight, and easy maintenance conduit that has stood all the expectations of industries that have delicate and sensitive information and data to be transferred through cabling.
