What holds pipes together?

Today, the plumbing sector is one of the most important parts of construction. If you use quality plumbing fixtures, you can be sure that there is no need to replace the plumbing for a long time. One of the elements used in plumbing is fitting. The fittings actually hold the pipes side by side in the same building.

There are different type of tee fittings or types of pipe joints that we can name some of them as: Brass Flare x MIPS Adapter, Stainless Steel Bushing, PVC Cap, Chrome Coupler, Copper 90° Elbow, Black Iron Floor Flange, Chrome Pipe Nipple, Brass IPS Tee and … . There are many types of plumbing pipes for residential or commercial buildings. plumbing pipes such as PEX, Copper and PVC are used normally depending on their application and the location in which they are installed. In addition there are some other plumbing pipe types such as black, galvanized and brass. Let’s see below the best application for the most common used plumbing pipes.

Stainless steel can look very neat but it is very expensive.Stainless steel pipe are used in areas subject to corrosion and near coastal areas. This type of pipe is available in both flexible and rigid and will need some special couplings to be attached to other types of pipes. Do not confuse stainless steel pipes with galvanized pipes. It is available in various sizes and lengths. also you can prepare your reducer pipe if you want.

How are plumbing fittings measured?

The easiest way to find what nominal fitting size you need is to use follow these steps:

  • For Male Threads:
  • Measure the Outside Diameter (OD) of your pipe or pipe fitting
  • Wrap a string around the pipe
  • Mark the point where the string touches together
  • Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
  • Divide the circumference by 3.14159
  • Then use the nominal diameter conversion chart to find the nominal diameter (pipe size).
  • For Female Threads:
  • Measure the Inside Diameter (ID) of your pipe or pipe fitting (use a ruler or tape measure).
  • Use the chart on this page to find the nominal diameter (pipe size).

What are plumbing fittings made of?

For plumbing and water supply, some of the commonly used and best pipes and fittings are as under:

  1. Cast iron: Cast Iron pipe is widely used for city water-distribution systems because of its high resistance to corrosion and consequent long life. Cast iron pipe is made from pig iron. Such pipes are normally made from 5 cm to 120 cm in diameter. Under normal conditions, a cast iron pipe can be expected to last 100 years.
  2. Galvanized Iron (G.I): G.I pipes are made of mild steel sheet. Its length-wise joint is Welded Seam Type. G.I pipe is used to supply water, gas or any other liquid inside the building. These types of pipes are prepared from 12 mm ( 0.5 inches) to 15 cm ( 6 inches) in diameter. They are available in 6 meters ( 20 feet) length.
  3. Wrought Iron: These types of pipes are like G. I. Pipes. They are also used to carry water, gas or certain other liquid from one place to another. The only difference between wrought iron pipe and G.I is that wrought iron pipes are prepared by welding wrought iron sheet. In addition, seamless pipes are also made. The weight of such pipe is less. Cutting, threading, and bending of this pipe is quite easy.
  4. Steel: Steel pipes are used to carry water, gas or certain other liquid from one place to the other under pressure. These pipes are made from steel sheets. Small pipes have welded joint along the length which is not visible. Large pipes have riveted joint or welded joint. After making such pipes, they are dipped in Zinc solution. This action is called Galvanizing and is used to prevent the pipe from rusting. The average age of such pipes is from 25 years to 50 years.
  5. Copper: Copper pipes are made of small diameter. Since copper does not admit rust, so these pipes are durable. However, as copper is costly, therefore, they are used in limited places. These types of pipes are generally used to carry hot water or steam. They do not bend or sag even at high temperature.

Nowadays in the continent of Asia different countries are active in the production of different types of pipes and fittings, which is one of the lucrative businesses in the market.

Is plastic plumbing as good as copper?

The general properties and engineering of plastic pipes can be
controlled by standards, and in many applications there can be several
choices due to the overlap of properties between different plastics.
Therefore, it is necessary to fully understand the position of the user
and to master the different properties of the various types of plastic
pipes. In general, the following advantages can be considered for all
plastic pipes:

  • Corrosion resistance: Plastic pipes do not
    corrode most of the chemicals present in domestic wastewater and also
    have minimal resistance to the passage of other wastewater and other
    fluids due to the smooth surface. These pipes will never rust and will
    not corrode.
  • Lightness and ease of transportation: In addition
    to ease of transportation and cost reduction, in the case of plastic
    pipes cutting, joining and installation is much easier than other types
    of pipes such as metal pipes.
  • Flexibility and toughness:
    Particularly in underground applications, the flexibility of plastic
    pipes reduces the number of connections and easily curves the plumbing
    paths.
  • Various connection methods: In general, plastic pipes
    have the ability to thread, flange, heat weld, glue, compressor and so
    on and provide a wide variety of connections for different conditions.
  • Excellent
    hydraulic properties: Plastic pipes fall into the group of flat surface
    pipes, which results in the least energy needed to transport the
    various fluids.
  • higher life and lower cost of installation and
    maintenance: Plastic pipes have been used in most cases for more than 22
    years and have not yet reached the end of their useful service life.

Plastic pipe restrictions:
The
first major limitation of plastic pipes is their strength and low
rigidity. In the next step, these tubes are susceptible to high
temperatures.

Features of Metal Pipes:

  • Corrosion from
    inside and outside and not easy deform ability: Metal pipes are less
    resistant to corrosion if exposed to oxygen and minerals. This will
    reduce the resistance of the metal pipes and shorten their service life.
    Metal pipes are not easily formed due to their high strength and
    require a great deal of bending to bend them.
  • High thermal
    conductivity and high deposition: Metal pipes have a high thermal
    conductivity and in other words, they will waste energy. The wall of the
    metal pipes is also rough and has a high absorption of water solids,
    which reduces their service life and reduces pressure and reduces water
    flow.
  • High pressure drop and high weight and installation
    problems: Not being smooth inside these pipes as well as using multiple
    joints in this type of piping reduces the high pressure in the water
    flow, which causes the large diameter pipe to be selected to relieve
    pressure drop. Also, these pipes cause a lot of transportation problems
    due to their high weight and their high weight and their flexibility
    creates many problems for installation.
  • Low life span: The
    useful life of steel pipes is often between 10 and 12 years, and after
    this period the building installation system will have problems such as
    pipes decay, bursting, changes in color and taste of water, and in some
    cases shedding part of the building. These problems will also pose many
    risks and will lead to the replacement of the installation system which
    will cost a lot.

Can you fit plastic pipe to copper pipe?

You can connect PVC or CPVC to copper in several ways. One common method is to solder a female threaded fitting onto the copper pipe, screw in a male threaded plastic fitting and finish up by gluing plastic pipe to the plastic fitting. This isn’t the best way, though, because you can’t tighten the fitting if it leaks. The best and most safe option is to use a copper-to-plastic adapter. Those with moderate do-it-yourself skills can complete this project.

Step 1: Prepare the ends of the pipes you plan to join by wiping off dirt with a rag and filing the edges on the copper pipe with a metal file to remove burrs. These burrs are the products of cutting with a hacksaw, and if you don’t remove them the pipe won’t slip into the fitting.

Step 2: Spread all-purpose plastic pipe primer onto the end of the plastic pipe and inside of a plastic-to-copper adapter, using the brush from the can. Make certain the primer works on both PVC and CPVC — most do.

Step 3: Spread all-purpose plastic pipe cement on both the end of the plastic pipe and the inside of the plastic side of the fitting with the brush attached to the can’s lid. Immediately push the fitting onto the plastic pipe. Give it a little twist, then hold it for 30 seconds until the cement sets.

Step 4: Unscrew the compression nut from the copper side of the fitting and remove the compression ring. Slide the nut and ring onto the end of copper pipe, push the end of the pipe fully into fitting, and screw the nut to the fitting.

Step 5: Tighten the nut with a pair of tongue-and-groove pliers, but don’t over tighten it. The nut squeezes the ring against both the pipe and fitting, forming a watertight seal. You don’t need to use pipe thread tape or pipe dope.

Is it better to use 4 inch plumbing fitting?

Conserving water is an admirable goal, and by running narrower PEX lines to some fixtures, you can reduce wasted water. but not all fixtures benefit from narrower lines. Most homeowners aren’t willing to wait 15 minutes to fill their bathtubs, so running a minimum 1/2-inch line to the tub is a good idea. Other fixtures that benefit from 1/2-inch lines are washing machines and dishwashers. Sinks and showers are water guzzlers, and you can conserve by running 3/8-inch lines to them. Because the rate at which a commode tank refills is usually not important, it’s okay to run 3/8-inch line there as well.
