Hi, I am a beginner in C2 analysis, and I designed on skid piping system where the tie-in flange loads need to be taken in to account for off-skid piping stress analysis and client is asking for the same. Since I didn't consider support at tie-in flanges, how I will generate loads and moments...

Hi, I have a project in which API 10000 valves are used with material class EE & also HH as per API 6A, body/bonnet/flanges/end connectors shall be 60K material. We use API 694 F60 as body/bonnet/flanges which is a 60k material and SS 316/316L for trim material which is a 30k material...

Hi, I work for a project in which there are API 10000 gate, globe, check and choke valves are included. But as per project specification there is no requirement for API Monogram. The only requirement is design shall be as per API 6A. But valve vendor facility is not qualified for API Q1. My...

Thanks jmec. Also please explain where i can see the allowable stress value for inconel 625 pipe in table K-1. It is not listed even in 2018 edition

Hi, I need to design high pressure piping as per ASME B31.3 section K304.1.2 with API 5L X60 pipe. When i checked for "S" value in Table K-1 under 300 deg F temperature it doesn't have any value. Which value should i consider for it. please advise

Dear , Sec.8 means ASME SEC VIII DIV 1

Hi, We need hydraulic accumulator tank of 25 Liter to operate hydraulic activities. Is it necessary to provide U stamp if we construct the accumulator as per sec.8. Project requirement is to follow sec.8.

DearS, Please refer attached calculation sheet for 1" NPS nipolet which is welded in 6" NPS pipe. I calculated the wall thickness as per B31.3 & B31.8. For both wall thickness calculation I need to provide actual OD of the pipe. My concern is Nipolet is with male NPT thread and at the tip of...

Dears, I am using ASME B31.3 appendix K for a high pressure 1" line. I used 12.5% for mill allowance, 0.236 as corrosion allowance as per project specification and 2 mm thread allowance. But in NPT type threads are inclined and OD will be lesser than the standard OD (1.32 "). so how should i...

Dears, For a 1/2" 1500 BLRTJ F321 flange, what would be the soaking time for stabilization heat treatment. As per S.10 of ASTM A182, 4.7 min/mm shall be considered. But which thickness should be considered. thickness with raised face or without raised face? Code does not give a clear picture on...

Dears, How to determine the required hydro test pressure for API 6A valves, flanges. Also thetest pressure for ASME flanges & valves for which the materials are not listed in relavent ASME standards (B16.5 & B16.34). for eg: 2" 1500# WNRTJ ASTM A694 F60. in this case 694 is not listed in...

Pressure 3000 psi and temperature 195 deg F

Dear weldstan The line is actually sour crude oil with design temperature of 3000 psi. We ordered 321 material accordingly. but later we found some shortage in material. But we didn't get SS321 material from any stockist due to very less qty and they don't have the same. Instead they have SS316...

Dear Shurjati, I just want to confirm with experts. that's why i raised this query. Regards, Ummer

Dear All, My WPS have been qualified for Pno-8 & Gno-1 with ER347. Both 316/316L & SS321 are comes under same P number & G Number. Can i use the same filler rod ER347 for this. one of my friend told me that even if the same filler rod is uder to weld these material. cracking possibility is...

Hi Weldstan, Will there be any metallurgical issue as 321 is stabilized one and 316 is not.

I have 321 pipe and 316L coupling. Can i weld this or need to thread without welding. could you anyone assist me.

I am using temperature load as 35 Deg(TEMP 35 MEMB ALL). But it produces huge stresses at foundation in Fx & Fy direction. I reduced this by giving weak spring (10 Kn/mm) at Fx & Fy. I am using M27 anchor bolt and Hole dia is 40 mm. So 6.5mm gap will there all around bolt. Now my concerns is how...

Dears, How to find COG of complicated frames with equipment and piping. is there any excel sheet for this.

Dears, I need to design foundation base plate for a channel. I am referring AISC manual (DESIGN GUIDE 1, 2ND EDITION / BASE PLATE AND ANCHOR ROD DESIGN) for anchor bolt design, there i have the formula for W section only. pleasse help on this
