What is the ASME U Stamp?

Introduction

We at Sure Flow stress the fact that our custom products are designed and manufactured to ASME Section

VIII, Division 1, urrent Edition! Wh"# $his write%up provides a histor" and the most important sectionsto &Sure Flow as a manufacturer'!

Sample of Sure Flow Equipment Inc. nameplate ASME U STAMPASME is the acron"m for American Societ" of Mechanical Engineers! Founded in 1((), ASME is a

 professional organi*ation focused on technical, education and research issues in the engineering andtechnolog" communit"! ASME develops and maintains internationall" recogni*ed industrial and

manufacturing codes and standards that enhance pu+lic safet"!

In 111, ASME formed a committee with the o+-ective of formulating a collection of standards to govern

the manufacture of steam +oilers and other pressure vessels! $his need +ecame apparent shortl" after theinvention of the steam engine in the late 1(th centur"! In the 1th centur" there were literall" thousands of

 +oiler e.plosions around the world, some of which resulted in man" deaths! $he committee is named the

/oiler and 0ressure Vessel ommittee! It is currentl" responsi+le for esta+lishing rules of safet" governing

the design, fa+rication and inspection during construction of pressure vessels, and to interpret these ruleswhen uestions arise regarding their content!

$he rules are compiled and pu+lished as the ASME /oiler and 0ressure Vessels ode! $he ode is divided

into 12 sections! $hese sections cover topics ranging from the construction of +oilers, pressure vessels,transport tan3s and nuclear power plant components, to the in%service inspection for pressure integrit" of

nuclear components and transport tan3s! $he most important sections to Sure Flow as a manufacturer of

strainers are Section VIII Division 1, &4ules for onstruction of 0ressure Vessels'5 Section II, &Materials'5Section V, & 6ondestructive E.amination'5 and Section I7, &Welding and /ra*ing 8ualifications'!

Since 119, ASME has accredited companies in the pressure vessel industr" to certif" that their products,

services and ualit" s"stem compl" with the ASME /oiler and 0ressure Vessel ode! When dealing withstrainers, this acceptance and certification is s"m+oli*ed +" the &: Stamp' for pressure vessels and &:MStamp' for miniature pressure vessels! Sure Flow is authori*ed +" ASME to use the : or :M ode

S"m+ols, as applica+le, on strainers +uilt in strict accordance with the provisions of the ode! $he S"m+ol

on a vessel is used to confirm the stamped item is in conformance to the latest edition of the ode!

:sing the ASME ode S"m+ol Stamp is a wa" of compl"ing with the laws and regulations in all the provinces of anada and all ;) states in the :!S!A! In addition, it has +een estimated that over 1))

countries accept the ASME /oiler and 0ressure Vessel ode as a means of meeting their government safet"

regulations!

$he reuirements of appl"ing a : or :M ode S"m+ol to a strainer encompass the whole process fromdesign to purchasing to production and testing!

Starting right with the design, there are rules to +e followed! 0arameters such as wall thic3nesses, materials,

flange ratings, welding details, and e.tent of nondestructive e.amination are determined +" design

conditionssuch as pressure, temperature, corrosion allowance, fluid running through the strainer, and an"specific reuests from the customer! /ased on these conditions a comprehensive set of calculations are

 prepared! $he" are reviewed and approved +" the ASME Inspector!

<nce the design has +een approved, the materials can +e purchased! Materials used must compl" with the

/oiler and 0ressure Vessel ode, in particular Section II 0arts A through D! Material $est 4eports arereuired for all materials! $hese reports include such things as chemical anal"sis, heat treatment performed

=as applica+le> and an" 6DE testing results! 4eview of the reports will determine if the material is in

compliance with the ode reuirements! $he reports are supplied +" the vendor with the material! Allmaterial must +e clearl" identified to trace it to the applica+le Material $est 4eport! $he ASME Inspector

will chec3 the material and review the Material $est 4eports to ensure their conformit" to the ode!

/efore production can +egin, the Inspector will verif" that the weld procedure to +e used has +een ualified

and the welders performing the welding are certified! $his is in accordance with Section I7! At the sametime, the Inspector will inform us of the e.tent of his inspection on the fa+rication part of the -o+! :suall",

he will want to see the strainer fit%up, that is the unit -ust +efore the welding is performed! $he ne.t step is

to review the unit after fa+rication is complete to ensure welding was performed to ode reuirements! At

the same time, he will review an" nondestructive testing results! $hen he will witness a h"drostatic test performed in accordance with the reuirements of Section VIII Division 1! $he final step is the application

of the nameplate! $his is also witnessed +" the Inspector! $he nameplate will +e mar3ed with relevantdesign conditions and the : or :M ode S"m+ol!
