tests conducted on pipe as large as 24-in. (600-mm) diameter have shown these stress values to be valid for larger diameter PVC pipe. NOTE 5—PVC pipe made to this specifiion is often belled for use as line pipe. For details of the solvent cement bell, see

Materials Used in Water Supply Pipes

PVC stands for polyvinyl chloride. Of the different types of plastic pipe used for water supply, PVC has a wide variety of pluing uses, from drainage pipe to water mains. It is most commonly used for irrigation piping, home, and building supply piping. PVC is also

K-factors, Y-factors, and press brake bending precision

7/3/2018· Types of Bends First, let’s step back and talk about the types of bends you can make in sheet metal. Have no fear; I will bring the K-factor into the discussion soon. Until then, bear with me. There are four types of bends: minimum-radius, sharp, perfect, and radius.

Polyvinyl chloride - Wikipedia

PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile appliions such as doors and windows. It is also used in making bottles, non-food packaging, food-covering

Guide on How to Choose the Right Pluing Pipe

There are many types of pluing pipes for residential or commercial buildings. Pluing pipes such as PEX, Copper, and PVC are normally used depending on their appliion and the loion in which they are installed. Also, there are some other pluing pipe

PIPE FITTING FRICTION CALCULATION can be calculated based on the following formula where K …

PIPE FITTING FRICTION CALCULATION The friction loss for fittings depends on a K factor which can be found in many sources such as the Cameron Hydraulic data book or the Hydraulic Institute Engineering data book, the charts which I reproduce here in

Chapter 6 - Design of PE Piping Systems - Plastics Pipe Institute

Chapter 6 Design of PE Piping Systems 159 The Hydrostatic Design Stress, HDS, is the safe long-term circumferential stress that PE pipe can withstand. It is derived by applying an appropriate design factor, DF, to the Hydrostatic Design Basis, HDB. The method

A Beginner''s Guide to PVC Fitting End Types

If you''ve worked with PVC pipe for any length of time, you will know that there are many different PVC end types. From spigots to barbed inserts, the look and purpose of different PVC end types vary widely. For newcomers to the wide world of PVC, this may be

Losses in Pipes

Like pipe friction, these losses are roughly proportional to the square of the flow rate. Defining K, the loss coefficient, by allows for easy integration of minor losses into the Darcy-Weisbach equation. K is the sum of all of the loss coefficients in the length of pipe
