PVC Piping

 

PVC (Poly Vinyl Chloride) is a thermoplastic type of plastic ( Plastic that can be softened by heating). It is sometimes known as ‘Vinyl’ in Europe and predominantly so in North America. In Europe, ‘Vinyl’ usually refers to certain specific flexible applications, such as flooring, decorative sheets, and artificial leather.

PVC is a thermoplastic made of 57% chlorine (derived from industrial-grade salt) and 43% carbon (derived predominantly from oil/gas via ethylene). It is less dependent than other polymers on crude oil or natural gas, which are nonrenewable, and hence can be regarded as a natural resource-saving plastic, in contrast to plastics such as PE, PP, PET, and PS, which are totally dependent on oil or gas. This chlorine gives PVC excellent fire resistance.

International Standard for PVC Piping

They are manufactured conforming to various world Standards: ISO 4422 and ISO 3633, DIN 8062, ASTM-D-2241 and ASTM-D-1785, IS 4985, IS 12231, and IS 13592.

ASTM D1785 “Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80, and 120” is manufactured to meet the needs of a broad range of industrial, commercial, and residential piping systems.

ASTM D1785 covers pipes made for water distribution and irrigation systems.

Properties of PVC PipingPVC Piping is Non-Toxic.

PVC Piping is strong and rigid.

PVC Piping is resistant to almost all acids, corrosive liquids & gases.

PVC Piping may be damaged by some solvents and chlorinated hydrocarbons.

Maximum usable temperature 140 deg F (60 deg C).

Usable for water, gas, and drainage systems.

Not usable in hot water systems.

PVC Piping Joints

They are available in Solvent Weld Socket Joint as well as in Rubber Ring Socket Joints.

The Selfit (Solvent Cement Joint) pipes have one end self-socketed and the other end plain, which fits snugly without the use of copiers. The strong solvent cement joint is permanent and trouble-free.

PVC Piping Size Range

20 mm to 560 mm.

PVC Piping ApplicationsPotable water supply Schemes,

Domestic/Industrial Plumbing,

Soil, Waste, and Rain Water Drainage Systems,

Lift & Gravity Irrigation Systems,

Chemical transportation,

Agriculture Pumpset Suction and Delivery Pipes,

Rising Main & Distribution Lines.

PVC Piping Fittings

PVC Pipe

PVC pipes are either selfie i.e. joined by solvent cement or with gasket connections.

PVC Pipe

Gasketed PVC Pipe

Equal Tee

Used for branch connection of the same size as the main pipe in PVC piping. This is a molded PVC fitting

PVC Reducing Tee

Used for branch connection of size less than main pipe in PVC piping. This is a molded PVC .

PVC Reducing Tee

Elbow

Used for 90-degree direction change of PVC piping. This is a molded PVC fitting.

PVC Elbow

Coupler

This fitting is used to connect two pipe pieces in case of a single piece of pipe is not sufficient for the required straight length. This is a molded PVC fitting.

PVC Coupler

End Cap (Plain / Threaded)

This fitting is used to terminate a PVC pipe in case it is a dead end, or for future extension. It is a molded fitting.

PVC End Cap

Service Saddle

Service saddle is used to support PVC pipes in the field.

FTA ( Female Threaded Adapter)

This fitting can be used as an interface to threaded steel pipes or to connect male threaded valves of steel or plastic.

MTA (Male Threaded Adapter)

A male-threaded adapter is used to connect female-threaded fittings of steel or plastic.

Reducer Bush

A reducer bush is used to abruptly change the diameter of the pipe. It causes more pressure loss than a normal reducer.
