stress – strain curve :

stress – strain curve Stress = Force / Cross sectional area Strain = Deformation / Original Length

ALLOWABLE STRESS :

ALLOWABLE STRESS = 1/3 X TENSILE STRENGTH. = 2/3 X YIELD STRENGTH .

stress in pipes :

stress in pipes Circumferential or Hoop Stress Total force acting on longitudinal section = Intensity of Pressure x projected area = p x d x l - - - - - - - - - eqn – 1 Total Resistance force acting on cylinder wall = Intensity of Pressure x projected area = h x 2t x l - - - - - - - - - eqn – 2 From Equation 1 & 2 h = p x d / 2t

stress in pipes :

stress in pipes Longitudinal Stress Total force acting on transverse section = Intensity of Pressure x cross section area = p x π /4 d^2 - - - - - - - - - eqn – 1 Total Resistance force = Intensity of Pressure x projected area = L x π d t - - - - - - - - - eqn – 2 From Equation 1 & 2 L= p x d / 4t

SCHEDULE NO :

SCHEDULE NO SCH . NO = 1000 P /S P = Internal pressure (PSI) S = Allowable Tensile Strength Sch. 5 , Sch.10,Sch.20, Sch. 40, Sch.80,Sch.160. Sch.XS, Sch. XXS Sch. 5 S , Sch.10 S ,Sch.20 S , Sch. 40 S , Sch.80 S ,Sch.160 S . Sch.XS, Sch. XXS :- S = Stainless Steel

pipe wall thickness calculations :

pipe wall thickness calculations Tm = t + c = P Do / 2(SEW + PY) + C P = Internal pressure (PSI) Do = Outside Diameter. S = Allowable Tensile Strength E = Joint Efficiency factor W = Weld joint strength reduction factor Y = Coefficient.

piping materials :

piping materials MATERIAL SELECTION STRENGTH - Pressure. DUCTILITY OR FORMABILITY - Stress. TEMPRATURE CORROSION RESISTANCE FATIQUE

piping materials :

piping materials PIG IRON Note – Pig iron contains ‘2%’ to ‘3%’ Carbon. 2C + O 2 2CO 2CO + O 2 2CO 2

piping materials :

piping materials PIG IRON Note – At high Temperature more than 300 Deg C. oxygen bubble get expand rapidly - So to remove this oxygen from pig iron we are adding 0.1% Si (Silicon) which have high affinity towards the silicon Si + O 2 Sio 2

piping materials :

piping materials CARBON STEEL - Then we will get Deoxidized steel called as “ KILLED STEELS “ - Si(Silicon) is doing Deoxidizing Process. - ASTM A 106 Gr . A - 0.25 C , 0.1 Si. Gr. B - 0.30 C , 0.1 Si. Gr . C - 0.35 C , 0.1 Si.

piping materials :

piping materials ASTM A – 53 A – Indicate Ferrous material as a main material B – Non Ferrous material. C – Non Metallic material. Note – If Carbon content more than “ 0.35 ” material becomes Brittle - Material contain carbon more than “ 0.35 “ are not weldeble

piping materials :

piping materials SOFTENING TEMP = 0.4 X MP (Melting point) = 0.4 x ( 1535 + 273) = 723 deg . K = 450 deg. C ( 723 K – 273 K) “Above 450 deg C “ STRENGTH PITTING SCALING CREEP

piping materials :

piping materials So that’s why for application more than 450 deg. C We have to add Cr ( Chromium) = STENGTH ELONGATION Mo ( Molybdenum) = STENGTH ELONGATION

piping materials :

piping materials ALLOY STEELS Used for the application in which temp. is Above 450 deg C “ Ex. ASTM A 335 P11 = 1 – 4% Chromium , 0.5 % Molybdenum ( 510 deg C.) P22 = 2 – 4% Chromium , 1 % Molybdenum ( 565 deg C.)

piping materials :

piping materials ALLOY STEELS But at the Temp. 400 Deg . C. the carbon in the steel gets activated & react with chromium to formed “ Chromium carbide” C 11 + Cr 22 Which increase Corrosion in boundary levels. “SENSILIZATION “ Chromium carbide formation Depletion of chromium at grain boundaries

piping materials :

piping materials LOW TEMPRATURE STEELS For Application of pipe in -250 Deg. C , We can use Ni ( Nickel) as a ingredient which increase ductility & strength Elongation Strength At low temperature material becomes brittle For that Ni is best solution

piping materials :

piping materials “STAINLESS STEELS TREE” Carbon content in the steel is responsible for the “Sensilization” for that we are adding ‘ Titanium ‘ Carbon has high affinity towards the titanium than chromium & chromium get safe that avoid Sensilization of ‘C’

piping materials :

piping materials “STAINLESS STEELS TREE” 304 18% Cr ,8% Ni,0.1% C 304L 18% Cr ,8% Ni,0.O3% C 317 18% Cr ,8% Ni,0.1% C 316 18% Cr ,8% Ni,0.1% C 321 18% Cr ,8% Ni,0.1% C 347 18% Cr ,8% Ni,0.1% C 348 18% Cr ,8% Ni,0.1% C 2% Mb 4% Mb Titanium (10% of Carbon) Cb + Nb Cb 308 19% Cr ,9% Ni,0.1% C 309 20% Cr,12% Ni,0.1% C 310 25% Cr ,14% Ni,0.1% C WEAR RESISTANCE STEEL STABALIZED STEEL FOR HIGH TEMPRATURE APPLICATION
