Standard fittings like elbows and tees vary from manufacturer to manufacturer and a tolerance of 25% should be assumed in calculations. Precision engineered items like control valves and metering orifices will of course have much tighter tolerances, and these will usually be stated as part of the accompanying engineering documentation.
24-03-2020· The term "value chain" refers to the process in which businesses receive raw materials, add value to them to create a finished product, and then sell the finished product to consumers. A "supply ...
6. Loss through valves and fittings. Losses for these items are calculated by converting to equivalent length of piping and adding to the total pipe length. 7. Loss caused by pipe friction can be calculated when the pipe size, the pipe length and the flow through the pipe are known. With these three items, the friction loss can be determined.
06-08-2016· Tee type Pipe Fitting Tee type fitting is a component of plumbing system which is in T-shape. It is having one inlet and two outlets, outlets are arranged at 90 o to the main line connection (inlet). It can also be used to combine the flow from two inlets to one outlet. They are also available in different materials and different sizes.
The following types of fittings are included in the product pipe system: Straight pipes, bends, tees, reducers and unions; Special fittings such as sight glasses, instrument bends, etc. Valves for stopping and directing the flow; Valves for pressure and flow control; Pipe supports

It is equivalent to the "old" 3.1.B certificate. This is an inspection certificate according to EN 10204:2004 that declares the 'metallic products' are in compliance with the order requirements and supply test results. We do not release any material for production until a satisfactory material certificate is received.
per the requirement. Fittings are fixed in the plumbing system to join straight pipes or any section of tubes. We can say that the water-supply fittings like elbow, tee, socket, reducer, etc., are fitted to change the direction of flow, distribute the water supply from the main pipe to other pipes of equal size or lower size, etc.
G2.3 Water fittings and materials for water fittings complying with paragraph 2(1) of Schedule 2 should be tested by an approved test house and the results published in approved lists. G2.4 When water fittings or materials are specified to a British Standard or other document, the reference is to the latest available edition of the

Manufacturers of pipe work fittings and valves often publish a fitting's associated 'K' factor. Pipe Fitting Loss Formula. Fluid head loss through a fitting can be calculated by the following equation: h = K x v² / 2g where h = pressure loss in terms of fluid head, i.e. fluid head loss K = manufacturer's published 'K' factor for the fitting
Fittings such as elbows, tees and valves represent a significant component of the pressure loss in most pipe systems. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method. The strength of the equivalent length method is that it is very simple to calculate.
The below mentioned flow equation describe the flow rate of a fluid through a valve. The form of this equation used by valve suppliers is: where C is the valve flow coefficient, q the flow rate of the liquid through the valve, Δp = p1 – p2 the pressure difference across the valve and G the specific gravity (relative density) of the fluid.
Calculate friction losses for fittings and valves in a section of pipe expressed in equivalent length of pipe (in feet). Example: Your section of 2" pipe has 2 x gate valves, 2 x 90° elbows, 4 x straight true tee's and 12 branch tee's Select 2" for nominal pipe size and enter 2 gate valves, 2 90° elbows, 4 straight true tee's and 12 branch tee's.
03-09-2016· Fittings can also include items that are hung by a nail or hook such as mirrors or paintings on the wall. These items are not usually permanent items of a house. All the free standing furniture in the room, including couch, chairs, tables, ornaments as well as the plant and the carpet can be considered as fittings.
At the time of fires, by manipulating the cut-off valves, plenty of water supply may be diverted and concentrated for fire-fighting. Disadvantages: Cost of pipe laying is more because relatively more length of pipes is required. More number of valves are required. The …

for individual valves. THERMOPLASTICS ARE NOT RECOM-MENDED FOR COMPRESSED AIR OR GAS SERVICE.* This guide considers the resistance of the total valve assembly as well as the resistance of individual trim and ﬁ tting materials. The rating assigned to the valve body plus trim combinations is always that of the least resistant part.
24-03-2020· While many people believe logistics—or the transportation of goods—to be synonymous with the supply chain, it is only one part of the equation.
the supply source. These pressures are as follows: 1. Pressure required at fixture to produce required flow. See 607.3 and 607.4. 2. Static pressure loss or gain (due to head) is computed at 0.433 psi per foot (9.8 kPa/m) of elevation change. Example: Assume that the highest fixture supply outlet is 20 ft (6.1 m) above or below the supply source.
05-01-2015· Globe valves are available with either linear or equal percentage inherent characteristics, giving them versatility not generally available with the rotary valves. In fact, most globe control valve designs can be changed from linear to equal percentage (and vice versa) by changing the trim.
