With shallow grooves attached into raised surface, this flange face assures a positive grip with the gasket. Instead a round metallic ring is used that rests in a deep groove cut into the flange face. The donut-shaped ring can be oval or octagonal in design. As the bolts are tightened, the metal ring is compressed, creating a tight seal. The ring and groove design actually uses internal pressures to enhance the sealing capacity of the connecting flanges. Using a gasket material softer than two adjoining flanges is an excellent way to eliminate the possibility of a fluid escape.
Gaskets can be made of materials such as asbestos, rubber, neoprene, Teflon, lead, or copper. Flanges are designed to match the bolt circle and bolt hole dimensions of other flanges that are of the same and bolt diameter and pressure rating. Bolts are available in two types, machine or stud. Machine bolts have a "head" on one end and threads on the other.
Stud bolts have threads throughout their entire length and require the use of two nuts. Valves can Control not Only the flow but also the rate, the Volume, the Pressure and the direction of a fluid within a pipe.
STEM Stem can be moved manually or to be driven hydraulically, pneumatically or electrically under remote or Automatic control or mechanically by weighted lever, Spring etc. Piping Stress analysis is a term applied to calculations, which address the static and dynamic loading resulting from the effects of gravity, temperature changes, internal and external pressures, changes in fluid flow rate and seismic activity.
Codes and standards establish the minimum requirements of stress analysis. The piping engineers can provide protection against some of these failure modes by performing stress analysis according to piping codes. This phenomenon is known as creep. Note: maximum or minimum normal stress is called principal stress.
Primary stresses are not self-limiting. These displacements can be caused either by thermal expansion or by outwardly imposed restraint and anchor point movements. Secondary stresses are self-limiting. Peak stresses are the highest stresses in the region under consideration and are responsible for causing fatigue failure.
The longitudinal stress due to internal pressure. Bending stress is zero at the neutral axis of the pipe. The hoop stress varies throughout the pipe wall. Shear Stresses tend to cause adjacent planes of the pipe slip against each other. Examples are a chemical plant, petroleum refinery, loading terminal, natural gas processing plant, bulk plant, compounding plant and tank farm.
The loadings required to be considered are pressure, weight live and dead loads , impact, wind, earthquake-induced horizontal forces, vibration discharge reactions, thermal expansion and contraction, temperature gradients, anchor movements. The thickness of the pipe used in calculating SL shall be the nominal thickness minus mechanical, corrosion, and erosion allowance.
The sum of the longitudinal loads due pressure, weight and other sustained loads and of stresses produced by occasional loads such as earthquake or wind shall not exceed 1. The loads can be classified into three categories. They are primary loads, secondary loads and occasional loads. The response of the piping to various loads is different. The primary load is also known as sustained load.
The primary loads are due to self-weight of the piping, its contents, insulation, refractory, inner casing, outer casing, internal pressure and external pressure. The secondary loads are due to temperature change and relative settlement of foundations. The occasional loads are due to wind, earth quake, water hammer, steam hammer, safety valves blowing jet reactions, surge load, blast load and accidental loads.
If the piping is not provided with adequate supports, it will be over-stressed and excessively deform. Over-stressing will cause premature failure. Excessive deformation will impair the performance of piping. Even though, it allows the horizontally mounted pipe to move vertically, it prevents the vertically and horizontally mounted pipe from any side movements.
REST This is a support in the vertical direction only upwards , it represents the support under the Flanges and valves. Constant effort spring hangers are usually incorporated for vertical thermal movements in excess of 50mm.
Usually variable load hangers are made of helical springs. The load varies from cold condition to hot condition. There are several types of constant load hangers. They are safer when compare with expansion joints but take more space. Expansion loops may be symmetrical or non-symmetrical.
Symmetrical loops are advantageous to use because leg is used efficiently to absorb an equal amount of expansion from both directions. The Expansion loop is usually located on the side of the hottest line. The Expansion loop, as a rule, should be located in the center of the distance between two anchors. The height of the expansion loop is normally twice the width. Bellow joints are tubular metal conduits with thin walled toriodal convolutes, which greatly reduce the axial stiffness of the conduit.
Bellows are intended to control the pipe stresses and strains caused by the natural thermal expansion of material as it changes from ambient temperature to steady state temperature during start up and in reverse direction during shut down. Pipe axial stresses and strains are controlled by bellows.
The change in bellow length is met with relatively little existing force because of the inherent flexibility of toroidal convolutes.
The flexibility is expressed as a spring constant over the applicable range of axial compression for the specific bellow configuration. Point, and the objective of this book is to guide the piping engineer to that point. Although the.
