It is a controlling element. They are widely used in chemical process industries. It is used where throttling and shut off combination is required. It offers good flow characteristics.

Spherical Plug

This valve consists of a two-way globe and the ball rotates between resilient seats. It is compact and requires low maintenance and no lubrication.

Ball Valve

It this type of valve, the controlling element is a disc called as blade, vane or flapper, which rotates in horizontal or vertical direction and allows the fluid to flow. This valve is suitable for throttling or on-off operation at low pressure drop.

Butterfly Valve

A valve that permits fluid to flow freely in one direction and contains a mechanism to automatically prevent flow in the other direction. It is principally used in industrial piping connections for gas, water, steam, air and other general vapor services.

Check Valve

This valve used on cold water system, heating system, compressed air lines and other pipeline with excessive pressure.

Safety Valve

A tubular section or hollow cylinder, usually but not necessarily if circular cross-section, used mainly to convey substances which can flow.

Pipe

This pipe is made of asbestos fibers and Portland cement and formed under pressure to created a durable and strong pipe. The thickness of the pipe is twice as that of the standard cast iron pipe which make it remarkably superior for embedment in concrete structure for having the same material properties. It can be used as soil, waste, ventilation and downspout.

Asbestos Pipe

It is one of the oldest plumbing materials used by Egyptians, the Greeks and Roman builders as soil and waste pipe such as floor mounted water closets. Also for radioactive wastes and for special laboratory corrosive wastes. Lead is highly resistant to acid and is suitable for underground installation. But because lead is poisonous, it is never used to convey water for human consumption.

Lead Pipe

It is durable and corrosive resistant material. Although it is little more costly than other pipe, this is the most popular water supply pipe, its fitting are cost lesser than steel pipes. It has a smooth surface inside that allows it to accommodate larger quantity of liquid even in a small diameter.

Copper Pipe

They are suitable for hot and cold water supply system and sanitary system (DWV), air conditioning, refrigerator and liquid petroleum gas piping.

Copper Pipes

This type of copper pipe is the heaviest and thickest, it is generally suitable for underground plumbing installation. It is available either rigid(hard temper) or flexible (soft temper),soft temper is also available in coils.

Type K

This type of copper pipe is lighter than type K, it is most popular for use in water supply of residential and radiant heat installation. Same as type K it is available either hard or soft temper, and in coils.

Type L

This type of copper pipe is used for branch supplies where water pressure is not too great, but it is not used for risers and mains. It is in hard temper only and is available in straight lengths.

Type M

This type of copper pipe is the thinnest copper tube and is main application is for the non-pressure installation. It is made in hard temper only same as the type M.

DWV

This pipe is known as “Gray Cast Iron”. The most popular and specified material for drainage system. It is suitable for plumbing needs of a 25- storey building or less. It is however not suitable to a building exceeds 25-storey because of vibrations of the building which can affect and cause water leak of the pipe joints.

Cast Iron Soil Pipe (CISP)

This pipe is also prone to corrosion caused by the action of Carbon Dioxide, Sulfur Oxide and Methane gases which can leads to rust due to oxidation.

Cast Iron Pipe

Extra heavy duty pipe and generally used for underground installation.

XV Type (CISP)

Standard duty and generally used for Building Installation.

SV Type (CISP)

This kind of CISP is used for well-fitted hub and spigot connection

Standard Pipe

This kind of CISP recommended when the length of pipe needed is more than 150 cm long where cutting is not necessary.

Single Hub Pipe

This kind of CISP is preferred when a piece of pipe is shorter than 150cm long when the pipe is cut, both end cans serve as joint connector.

Double Hub Pipe

This kind of CISP acts as a substitute to standard pipe and does not need caulking of joints anymore. Cheaper and easily connected using a neoprene rubber sleeves.

Hub less Pipe

A pipe that is made from alloy of cast iron and silicon. This is commonly used in laboratories, industries and other installations where acid wastes are being discharge. The characteristics of this pipe is brittle and requires stronger support for pipe that is installed horizontally to prevent sagging of joints.

Acid Resistant Cast Iron Pipe

It is for bell-and-spigot cast iron soil pipe (CISP) and other similar joints shall be firmly packed with oakum or hemp and filled with molten pig lead to a depth of not less than 25.4 mm.

Caulked Joint

This pipe is made out from mild steel, drawn through a die and welded, cast into 6 meters long.

Galvanized Steel Pipe

This pipe is not recommended for hot water supply system because temperature will deteriorate the quality of pipe faster.

Galvanized Steel Pipe

Pipe are linked by screwing with the help of threads, whereas one is a male thread and one is a female thread, in every junction.

Threaded Joints

This pipe is developed in Germany in 1935 and was introduced in the Philippines at the early 70’s.

Plastic or Synthetic Pipe

This pipe pipe became more popular for waters supply system because its economic value and ease installation, especially on projects like low cost housing where cost is important.

Plastic Pipe

Types of Plastic Synthetic Pipes:

Rigid Type Flexible type

A plastic pipe that is usually black in color and its main application is for DWV system.

Acrylonitrile Butadiene Styrene (ABS)

A plastic pipe that is generally approved for pressure systems such as cold water supply, it is typically rated 23 °C and 690 kPa, thus it is not advisable for potable hot water distribution. Usually white or gray color but it can be in other colors. It is also available in coils

Polyvinyl Chloride (PVC)

This pipe is generally used for hot (rated 82 °C and 690kPa) and cold water supply, and fire suppression sprinkler system in residences. It is also used in sanitary drainage applications for its chemical resistance. Usually beige or tan in color.

Chlorinated Polyvinyl Chloride (cPVC)

This pipe is generally used for drainage, waste pipes, drain pipes,gutters and downspouts, almost replacing cast iron. it is know for having strong resistance against chemicals, sunlight, and oxidation of water.

Unplasticized Polyvinyl Chloride (uPVC)

This pipe is used in many industrial settings due to its chemical and thermal resistance, affordability, and cost. Use PPR PN 10 for cold water piping. Use PPR PN 20 for hot & cold-water piping.

Polypropylene (PP)

This pipe is generally used for septic tanks, drain fields, and storm sewer.

Styrene Rubber Plastic (SR)

This flexible plastic pipe is ideal piping material for a broad variety of applications such as potable water service or distribution lines, natural gas distribution, lawn sprinklers, sewers, waste disposal, and drainage lines. PE materials are generally resistant to most ordinary chemicals.

Polyethylene (PE)

This flexible plastic pipe is a specific type of medium- or high-density polyethylene. It is stronger and more stable than PE with respect to temperature extremes, chemical attack, and creep deformation. In contrast to metal pipes, it is freeze-break resistant.

Cross-linked polyethylene (PEX)

This flexible plastic pipe is generally used used in hot and cold water supply application, however because of several implications tied to this type it no longer recommend for used in building plumbing system.

Polybutylene (PB)

A common method for joining plastic pipe and fittings. A fast and easy installation that uses solvents and CPVC resin to chemically fuse the pipe and fitting. It sometimes mistaken as gluing but in the process the solvent doesn’t adhere the two pieces instead it makes one continuous piece of plastic pipe. This process both use for pressurized and non-pressurized application, and commonly use for UPVC pipes.

Solvent Cement Joint/Solvent Welding

The simplest way of joining thermoplastic pipe is by cementing called ____________, it reduce 3/4 of the time it takes to make a bell and spigot joints.

Solvent Welding

An integral part of plumbing system to have a continuous length of pipe for pipe network, since pipe the length of pipes available is limited. This joint can make or break a pipeline depending on the technique and workmanship used to form the joint.

Pipe Joint

Compared to brazed and soldered joint, this joint main difference is that it melts the parts together and allows them to cool, resulting in fusion. Welding is usually used in metals and thermoplastics materials.

Welded Joint

Made of cement-based material, such as Portland cement, or mortar mix. The mortar is applied to the connection of bell and spigot of two adjacent cement pipe or fittings to make a watertight seal. Except for repairs and connections to existing lines constructed with such joints, cement mortar joints arc prohibited on new building sewers.

Cement Mortar Joint

Shall be a sleeve coupling of the same composition as the pipe or of other approved materials, and sealed with neoprene rubber rings or joined by an approved type compression coupling.

Asbestos Cement Sewer Pipe Joints

Produce by bolting two flanges together with a gasket in the middle to make a watertight seal. Flanged connection is considered as second most used method of joining after welding. Flanges have an extensive moment-carrying capability, this is critical for pipes that experience lateral buckling due to temperature and pressure changes (e.g. deep waterlines).

Flanged Joint

Where a fixture comes in contact with the wall or floor, the joint between the fixture and wall or floor shall be made watertight.

Joint

A plumbing fixture used to received human excrement and discharge it through a waste pipe using water as a medium to carry the waste. It is supplied with cold water connection. It is classified according to its Design, Make, Flushing mechanism, shape and installation.

Water Closet

Designed for the removal of urine and quick exchange of users. The fixture must contain the urine, flush it down the drain, and wash the exposed surfaces. It is provided with cold water connection. Urinals have been considered a fixture for the male population. Flushing style for urinals will be similar to the water closet.

Urinals

It is used for personal hygiene. It is provided with hot and cold water connection. It can be counter mounted, under counter mounted, or wall hung. It is intended to be used for washing one’s hands and face.

Wash Basin
