Di bawah ini adalah contoh dari calculasi terhadap penggunaan trust block dalam suatu system pmipaan yang dipasang di bawah tanah.Dan kebanyakan trust bloc ini dipasangkan ke pipa PVC .Untuk itu , dengan mengambil info dari http://www.engineeringtoolbox.com/ , kami uraikan perihalnya di bawah ini:

TRUST BLOCK

The resulting force on a thrust block or anchor depends on the fluid mass flow and flow velocity and the pressure in the bend.

Resulting force due to Mass flow and Flow Velocity

The resulting force in x-direction due to mass flow and flow velocity can be expressed as:

Rx = m v (1 - cosβ) (1)

= ρ A v2 (1 - cosβ) (1b)

= ρ π (d / 2)2 v2 (1 - cosβ) (1c)

where

Rx = resulting force in x-direction (N)

m = mass flow (kg/s)

v = flow velocity (m/s)

β = turning bend angle (degrees)

ρ = fluid density (kg/m3)

d = internal pipe or bend diameter (m)

π = 3.14...

The resulting force in y-direction due to mass flow and flow velocity can be expressed as:

Ry = m v sinβ (2)

= ρ A v2 sinβ (2b)

= ρ π (d / 2)2 v2 sinβ (2c)

Ry = resulting force in y direction (N)

The resulting force on the bend due to force in x- and y-direction can be expressed as:

R = (Rx2 + Ry2)1/2 (3)

where

R = resulting force on the bend (N)

Example - Resulting force on a bend due to mass flow and flow velocity

The resulting force on a 45o bend with

• diameter 114 mm = 0.114 m

• water with density 1000 kg/m3

• flow velocity 20 m/s

can be calculated by as

Resulting force in x-direction:

Rx = (1000 kg/m3) π ((0.114 m) / 2)2 (20 m/s)2 (1 - cos45)

= 1196 (N)

Resulting force in y-direction:

Ry = (1000 kg/m3) π ((0.114 m) / 2)2 (20 m/s)2 sin45

= 2887 (N)

Resulting force on the bend

R = ((1196 N)2 + (2887 N)2)1/2

= 3125 (N)

Note - if β is 90o the resulting forces in x- and y-directions are the same.

Resulting force due to Static Pressure

The pressure and the end surfaces of the bend creates resulting forces in x- and y-directions.

The resulting force in x-direction can be expressed as

Rpx = p A (1- cos β) (4)

= p π (d / 2)2 (1- cos β) (4b)

where

Rpx = resulting force due to pressure in x-direction (N)

p = gauge pressure inside pipe (Pa, N/m2)

The resulting force in y-direction can be expressed as

Rpy = p π (d / 2)2 sinβ (5)

where

Rpy = resulting force due to pressure in y-direction (N)

The resulting force on the bend due to force in x- and y-direction can be expressed as:

Rp = (Rpx2 + Rpy2)1/2 (6)

where

Rp = resulting force on the bend due to static pressure (N)

Example - Resulting force on a bend due to pressure

The resulting force on a 45o bend with

• diameter 114 mm = 0.114 m

• pressure 100 kPa

can be calculated by as

Resulting force in x-direction:

Rx = (100 kPa) π ((0.114 m) / 2)2 (1 - cos45)

= 299 (N)

Resulting force in y-direction:

Ry = (100 kPa) π ((0.114 m) / 2)2 sin45

= 722 (N)

Resulting force on the bend

R = ((1196 N)2 + (2887 N)2)1/2

= 781 (N)

Menghitung berat steel pipe

If the outside diameter and the wall thickness of a steel pipe is known, the weight per foot can be expressed as:

m = 10.68 (do - tw) tw (1)

where

m = weight per foot (lbs/ft)

do = outside diameter (inches)

tw = wall thickness (inches)

Example - Weight of 4" Schedule 40 Steel Pipe

The outside diameter (do) of 4" Schedule 40 Steel Pipe is 4.500 inches. The wall thickness is 0.237 inches. The weight per foot can be calculated using (1) as:

m = 10.68 ((4.500 in) - (0.237 in)) (0.237 in)

= 10.79 lbs/ft

PFD & P&ID , THE PARTS OF PIPING DESIGN ENGINEERPFD dan P&ID adalah bagian yang tak terpisahkan dalam terbentuknya suatu piping system karna induk dari semua itu adalh PFD dan P&ID..Untuk PFD , biasanya yang membuat adalah Process Design Engineer sedangkan untuk P&ID yang membuat adalah Process Engineer tapi yang ikut andil besar adalah Piping Design Engineer dan ControlSystem Design Engineer. Dimana mereka memberikan inputan-tambahan mengenai apa yang dibuat olehprocess engineer.

Dimana ini uraian ringkas mengenai PFD dan P&ID yang kami ambil dari http://www.engineeringtoolbox.com/ dan dalam bahasa Inggris. Gunakan goggle terjemahan bilamana kurang paham.

The Process Flow Diagram - PFD, a schematic illustration of the system

A Process Flow Diagram - PFD - (or System Flow Diagram - SFD) shows the relationships between the major components in the system. PFD also tabulate process design values for the components in different operating modes, typical minimum, normal and maximum. A PFD does not show minor components, piping systems, piping ratings and designations.

A PFD should include:

• Process Piping

• Major equipment symbols, names and identification numbers

• Control, valves and valves that affect operation of the system

• Interconnection with other systems

• Major bypass and recirculation lines

• System ratings and operational values as minimum, normal and maximum flow, temperature and pressure

• Composition of fluidsSystem Flow Diagrams should not include:

• pipe class

• pipe line numbers

• minor bypass lines

• isolation and shutoff valves

• maintenance vents and drains

• relief and safety valve

• code class information

• seismic class information

P&ID (PIPING & INSTRUMENT DIAGRAM)A Piping and Instrumentation Diagram - P&ID, is a schematic illustration of functional relationship of piping, instrumentation and system equipment components

P&ID shows all of piping including the physical sequence of branches, reducers, valves, equipment, instrumentation and control interlocks.

The P&ID are used to operate the process system.

A P&ID should include:

• Instrumentation and designations

• Mechanical equipment with names and numbers

• All valves and their identifications

• Process piping, sizes and identification

• Miscellaneous - vents, drains, special fittings, sampling lines, reducers, increasers and swagers

• Permanent start-up and flush lines

• Flow directions

• Interconnections references

• Control inputs and outputs, interlocks

• Interfaces for class changes

• Seismic category

• Quality level

• Annunciation inputs

• Computer control system input

• Vendor and contractor interfaces

• Identification of components and subsystems delivered by others

• Intended physical sequence of the equipment

This figure depict a very small and simplified P&ID:

A P&ID should not include:

• Instrument root valves

• control relays

• manual switches

• equipment rating or capacity

• primary instrument tubing and valves

• pressure temperature and flow data

• elbow, tees and similar standard fittings

• extensive explanatory notes

Demikianlah dari saya dan semoga bermanfaat buat teman-teman semua.

APA ITU PIPE STRESS ANALYSISAPA ITU PIPE STRESS ANALYSIS

Pipe Stress Analysis dalam Bahasa Indonesia adalah analisa tegangan yang terjadi pada pipa akibat dari perubahan temperature/suhu baik itu dari dalam ataupun dari luar pipa tu sendiri.Dari dalam pipa itu sendiri adalah :1. Fluida2. Flow 3. Gesekan

Sedangkan dari luar pipa adalah :1. Cuaca baik cuaca panas atau dingin2. situasi kondisi dmana dia dipasang, apa itu dalam tanah atau diatastanah.

Tapi yang jelas Pipe Stress Analisis berhubungan dengan material yang terkandung pada pipa. yach Pipa PCV, Pipa CS atau Pipa SS atau lainnya tentunya berbeda kemampuannya dlm mereduce stress.

Makanya sebelum kita menentukan/ menghitung Pipe Stress Analysys ada bainya kita lihat dulu jenis materials yang terkandung pada suatu pipa.

DIsamping dengan pembebanan yang trdapat pada pipa tersebut baik itu dari fluida, berat pipa itu sendiri

sistem perpipaan yang diberikan dalam pedoman yang ditetapkan oleh kode yang berlaku dan standar

industri tertentu.

Tujuan dari perpipaan fleksibilitas dan analisis stres adalah untuk menjamin keamanan terhadap: • kegagalan material perpipaan atau struktur dari overstress jangkar • kebocoran di sambungan • overloads pada peralatan terhubung

BAGAIMANA MENGLASIFIKASIKAN STRESS PADA PIPA :

A. Critical Service Piping Systems1. Pump, turbine, blower, and compressor piping2. Piping designed for 500 F or greater.3. Piping designed for 1000 psig or greater.4. Piping greater than 24 inches diameter.5. Piping connected to sensitive equipment, such as fired heaters, fin-fan coolers, reactors and boilers.6. Piping supported or guided from stress-relieved vessel.7. Jacketed piping.

B. Intermediate Service Piping Systems1. Piping designed for 250 to 499 F.2. Piping designed for 500 to 999 psig.3. Piping from 6 in. to 24 in.. diameter.

4. Nonmetallic piping.5. Vacuum lines.6. Pipeway and yard piping.

C. Mild Service Piping Systems1. Other piping not indicated in Critical and IntermediatePiping Systems.

What are the basic loads considered by the stress engineer?1. Primary Load (Sustained Load) – Refers to the type of load that remains constant throughout the operating life of a piping system. This includes the dead weight of the pipe, valves, insulation, flanges, snow, other mechanical loads, and the live load represented by the flowing commodity in the pipe.

2. Secondary Load (Thermal Load) – Refers to the type of load that goes through a cycle as the piping system heats up and cools down in its normal course of operation. Loads due to thermal expansion, anchor or structural movements due to wind or seismic, tank or equipment settlement are secondary loads.

3. Occasional Loads –Refers to the type of load caused by wind, seismic, psv discharge, water hammer, and slug flow effects. Pressure waves due to weapons blast effects are also considered occasional in nature.
