This ar­ti­cle dis­cusses in de­tail the var­i­ous re­quire­ments for de­sign, test­ing of pip­ing items from a man­u­fac­tur­ing per­spec­tive with re­spect to the two im­por­tant pip­ing spe­cialty items: steam traps and flame ar­resters.

Con­sol­i­dated in­for­ma­tion on Spe­cialty Pip­ing items is not read­ily avail­able – what­ever is avail­able is scarce and scat­tered. This ar­ti­cle seeks to ad­dress this as­pect and has put to­gether var­i­ous re­quire­ments/as­pects re­quired for the de­sign, test­ing of any SP items from a man­u­fac­tur­ing per­spec­tive. This ar­ti­cle dis­cusses in de­tail two im­por­tant pip­ing spe­cial­ity items: steam traps and flame ar­resters.

In oil and gas or any chem­i­cal in­dus­try pip­ing spe­cial­ity (also known as SP items) items play a very im­por­tant role. Most of these SP items are utilised to safe­guard var­i­ous process equip­ment such as pumps, com­pres­sors etc. Thus it is es­sen­tial to care­fully de­sign these SP items so that the plant op­er­ates safely and as per re­quire­ment. Faulty de­sign or wrong se­lec­tion of the SP items can lead to huge fi­nan­cial losses as well as can cre­ate un­safe en­vi­ron­ment within the process plant.

Un­like other bulk pip­ing items such as valves, pipes, fit­tings etc., these SP items are not pre­de­fined within pip­ing class spec­i­fi­ca­tion. Most of these items do not have ded­i­cated in­dus­try stan­dards but are used within the pip­ing sys­tem and hence are re­quired to meet the re­quire­ments set out in ap­pli­ca­ble pip­ing code, like de­sign, test­ing etc. One of the rea­sons for their non­in­clu­sion in pip­ing spec­i­fi­ca­tion is that they can change from project to project. Most of these SP items are ven­dor spe­cific and de­signed based on the process data pro­vided such as pres­sure, tem­per­a­ture, flow rates etc. There are var­i­ous spe­cial­ity items such as strain­ers, steam traps, flame ar­resters etc. Nor­mally process data sheets are pre­pared to spec­ify these SP items.
