Colors and Uses of PVC Pipe in the Philippines

colored pvc pipes in the Philippines
PVC (Polyvinyl Chloride) pipes are the most commonly used material for piping systems in the Philippines. The ASTM (American Society for Testing and Materials) is an internationally recognized organization that develops and publishes the standards for the pipe’s pressured and non-pressured applications.

General Uses

Some of the widely used applications of it, as per,  are piping systems for plant irrigations, sewers, drain-waste-vents, water service lines, water mains, conduit, and various industrial installations.


The above-stated uses of PVC for piping systems were based on the quality of the material to provide a long usage lifespan, resistant to corrosion, environmentally sound, easy to install, cost effective, and widely accepted. That is why many companies are using PVC for most of their piping systems. It can even last for a hundred years.

Color Indicators
Electrical Conduit
Gas Distribution
All Purposes

Speaking of pipe uses, according to,  there are some indicators to know which type of pipe is to be for every piping system. For most water systems, blue colored pipes are used in main pipes. For most fire systems, red colored pipes are used. Purple colored pipes are used for water reclamation systems.  Green colored pipes are used for sanitary water systems. Orange colored pipes are used for telecommunications pipelines. Gray colored pipes are used for electrical conduit systems. Yellow colored pipes are used for gas distribution lines. And the white colored pipes are used for all types of applications.

Of all the other products invented or discovered using PVC, the pipe is the most commonly used and marketed since the second world war. Aside from that, other materials for making pipes are so scarce during that period, that is why PVC prevailed among them and made its name throughout those past years as the most cost effective and reliable piping material.

How HDPE Pipe is Assembled and Installed

We have discussed the different types of HDPE Pipe Fittings from the first two posts. We define what  an HDPE Pipe is and the several types of it that are mostly used in the piping industry. While the third post talks about how the lack of piping system affects the Agriculture in the Philippines.

But today, we will talk about the assembly and installation of HDPE Pipes through this video that I found from YouTube. This is shared by the user “adsancorpipe” and is entitled as “HDPE Pipe Installation Video – HDPE Pipe Assembly”. The video was uploaded back in June 28, 2010. It is described as an Innovative Drainage and Water Conservation Solutions using the Corrugated HDPE Pipes.


We learn from this video that it is very important to join the pipes properly to maintain high level of performance that the pipe is designed to provide.

The Assembly of the pipe is showed in step by step procedure.

  •  It should be lowered to the trench. Two workers should be enough to handle an 18-inch or smaller pipes. Larger pipes are lowered using nylon straps.
  • Once the pipes are lowered to the trench, the pipes should be cleansed to remove foreign matter.
  • Apply an approved lubricant on the bell and spigot of the gasket so that it can be aligned properly.
  • After the pipes are aligned properly, it can now be assembled.

The method of assembly is demonstrated by the video and other installation process and tips on how the job can easily be done. But there are major things to inspect the alignment and assembly of the joints.

  • Improper Alignment
  •  Foreign Material Infiltration
  • Rolled Gasket

Failure to correct any of those will compromise the joint integrity of the pipes.

Shortening and fabricating of pipes are also discussed. Scenarios like that also happen on the site of installation. But a tip is demonstrated to easily fix them and ensure the proper joining of pipes. A cut & joint kit is needed to accomplish that.

Workers are reminded that the:

“Writing on the gasket should be facing up and out toward the end of the pipe. It is important that the gasket is seated properly.”

And we are warned that the failure to do it properly will once again compromise the joint integrity.

Another tip is using a homing mark and measurement of the mark on the bell to make sure that the assembly is fitted properly.

That’s it folks! Thank you for dropping by, I hope you enjoyed our pipeful discussion. J

Agriculture has greatly played a big part in the early economy of the Philippines and in the past, there were years when we became one of the great exporters of agricultural products in Asia.  But despite the drastic plans for industrialization of our country and the fast intervention of technology in almost every aspect of our society, Philippines is still considered as an agricultural country for most of our citizens in the rural areas are still supporting themselves with agriculture.

It is true that we have seen better days of our agricultural assets. Importing products like corn, coconut, sugarcane, and rice has greatly declined in the past years. There are many visible proofs that things are not going too well when it comes to our agricultural standing, especially in the farming industry. Instead of exporting, we are now importing rice. The climate has not been friendly for us too; frequent storm visits are ruining crops and the long droughts and El Nino are creating dead seasons for planting. Soil for farming is becoming unfertile due to chemicals and pollution. Almost every decade, there are food scares like foot and mouth disease, red tide, bird flu, and mad cow disease.  Fields are turning into residential subdivision lots and golf courses. There are also little efforts for agrarian reform. We also lack research facilities. And the greatest threat to improve agriculture in The Philippines is that it is very costly for farmers to sustain crop rotation, fund fertilizer, and install reliable irrigation systems.

The inadequacy in funding for development and research of projects that will actually help farmers has been a pressing issue that has pushed farmers to find alternative solutions to continue cultivate their farms. One of the best breakthroughs in agriculture, to adapt to poor irrigation and drought, is building an HDPE pipe irrigation and sprinkler system. These plastic piping are ideal for Philippine climate since there are no harsh winters that may freeze the water inside the pipes and water is less likely to evaporate during warm days. HDPE pipes and fittings are lightweight which make them easy to handle and transport, and it is also available in broad range of sizes. These HDPE pipes can also be extended as watering systems for hydrating poultry and live stocks; cleaning stables, coops, and pens; and humidity control—a perfect fit for both small and big scale farms.

Having a reliable HDPE pipes in the Philippines irrigation and water system does secure some of the agricultural needs and lessens other labors that usually takes longer to accomplish. This idea has also opened up the minds of agriculturist to try alternatives that will somehow answer to the current agricultural situation such as indoor farming which also makes smart use of HDPE pipes.

It is relieving to see that there are alternatives available to save the industry that is once the pride and glory of the country. Let this serve as a wake-up call for us about the things that we take for granted for progress’s sake before it become just an agricultural pipe dream.

Pipe Fittings Applications and Example Part 2

In my previous post, I have enumerated several pipe fittings Philippines, in this post; I will continue to add more types of pipe fittings and their example.

This is just brief descriptions of additional types of fittings, and there may be more of them and not posted here.

Pipe Wyes are another pipe fitting that allows one pipe to join another pipe at some degree or angle. It is named as Wye because its name suggests, it is a Y-shaped fitting.

Reducers according to Wikipedia is the component of a pipeline that reduces the pipe size from a larger to a smaller diameter. Normally, the length of the reduction is usually equal to the average of the larger and smaller pipe diameters. This also has two types, the concentric and eccentric reducer pipe fitting.

End Caps


End caps are pipe fittings that terminate a run by closing an end of the pipe. This used to stop liquid flow in a pipeline system.

Wall Anchors and Water Stops

Image Source:

Wall anchors are used as a support for pipes by strapping it around the pipe within a wall. This makes the pipe secure, aligned and supported from possible dents from the wall. The movement of pipes is also reduced. Water stops are used to ensure that prevents thrust movement and ensure positive water sealing.

Branch saddles

Image Source:

A pipe saddle is a structure that consists of a saddle and integral base that support the pipe by transmitting loads of forces to the adjacent structure. And branch saddles are used to make this support much stronger so the load is handled properly.

Transition Fittings


Transition fittings are the type of pipe fitting that is used mostly in natural gas distribution and systems. Most joint meeting in a piping system is supported by transition fittings.

Butterfly Valve Spacers

Image Source:

The spacers are the types of fittings that are used in butterfly valves and are placed between flanges and valve to prevent damage to the disc when opening the valve. The flanges must be positioned properly and the disc must be partially open.

That’s it folks, the second part of the post is done. Stay tuned for more pipe discussion.

This type of pipe fitting is a rigid ring that holds an elastomeric seal to its shape and place. It is commonly used with 0-Rings, lip seals and as reciprocating shaft seals.

Molded Ells

molded ell 90 degree pipe fitting

The standard molded ells have 45 degree and 90 degree ells that come in ¾ inch to 12 inch (IPS) and 4 inch to 12 inch (DIPS). This type of pipe is made through injection molding.

Fabricated Ells

Fabricated Fittings 90 Degree Elbow
This is a special type of molded ell pipe fitting; it has variety of sizes and ranges from two segment 45 degree fittings, up to five 90 degrees sweep elbows.

Molded and Fabricated Tees

Molded Tees pipe fitting

This type of pipe fitting is molded fitting that forms letter T. It can also be fabricated as reducing tees. Some forms are ButtXButtXSocket Tees, and ButtXButtXMPT Adapter Tees.


crosses pipe fitings

This pipe fitting is also called as the four-way fittings. The fitting becomes a cross if the branch line passes completely through a tee.

These are just some of the pipe fittings, their definition, application and sample picture. This post is for educational purposes only. I hope this is helpful and feel free to leave your comments and suggestions.
