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...
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
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,
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...
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,
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
Dears,
I am designing pipe supports for 4" pipes on a base frame. Loading data are provided from caesar II. I used W4x13 beams as a vertical beam for pipe support. A horizontal W4x13 is weleded above this column in which pipes will be U bolted. But when i analysed in staad most of the beams are...
Dears,
I have modeled a frame and analysed for in-process & lifting condition. during in-process i got excessive stress due to temperature load. So i provided 10Kn/mm spring at Fx & Fz to release the same. But what should i do while making concrete foundation to get this spring action.
During...
Dears,
I have a 8" sch 120 pipe as trucnnion for a frame with 200 mm length. the trunnion in connected to frame by welding a 25 mm thk plate ( 600mm length x 300 mm width ). How to check bending strength of the plate & trunnion pipe. is there any formula in AISC to check the same. Alos one side...
Dears,
I need to design bolted moment connection in base plate. Please check and advise on attached. The geen marking are the proposed design by myself.https://files.engineering.com/getfile.aspx?folder=791f1907-faa0-4496-bee9-f54ae7fc76de&file=1.pdf
