Aħbarijiet - ASTM A53 Ċart tal-piż tal-pajp ta 'tarf sempliċi

Il-piż tal-pajp tal-azzar huwa fattur ewlieni fid-disinn tal-inġinerija u l-istima tal-baġit, għalhekk id-dejta tal-piż preċiża mhux biss tgħin biex tiżgura stabbiltà u sikurezza strutturali iżda taffettwa wkoll l-ispejjeż tal-materjal u l-arranġamenti tat-trasport.

Sussegwentement, dan l-artikolu ser jagħti dettalji dwar it-tabelli tal-piż għalihomASTM A53Pajp ta 'l-azzar Plain-End u tiddiskuti kif tikkalkula l-piż speċifiku ta' pajp ibbażat fuq daqsijiet differenti u ħxuna tal-ħajt.

Ħarsa ġenerali lejn ASTM A53

ASTM A53huwa standard użat ħafna għall-pajp tal-azzar tal-karbonju, żviluppat minn ASTM (Soċjetà Amerikana għall-Ittestjar u l-Materjali).Dan l-istandard jispeċifika r-rekwiżiti tekniċi għal pajp tal-azzar tal-karbonju mingħajr saldatura u wweldjat b'reżistenza, li jintuża prinċipalment għat-trasport ta 'gassijiet, fwar, ilma, u fluwidi oħra u xi skopijiet strutturali.Minħabba l-prestazzjoni affidabbli u l-applikabilità wiesgħa tiegħu, sar il-materjal tal-għażla f'ħafna proġetti ta 'inġinerija.

L-oqsma ewlenin ta 'applikazzjoni huma t-trasport ta' fluwidi, bini u strutturi, l-industrija taż-żejt u tal-gass, bini ta 'magni, u sistemi ta' tisħin u tkessiħ.

Il-firxa tal-varjazzjoni tal-piż tal-pajp tal-azzar m'għandhiex teċċedi ± 10% tal-piż speċifikat.

Raġunijiet għall-Użu Mifrux ta' Skedi tal-Pipe

Id-diviżjoni tal-iskeda tal-pajpijiet tal-azzar tintuża ħafna, prinċipalment minħabba li tipprovdi sistema standardizzata għad-determinazzjoni tal-ħxuna tal-ħajt u d-dijametru ta 'barra tal-pajpijiet biex tiżgura l-kwalità u s-sigurtà tax-xogħlijiet ta' inġinerija.

L-iskeda tal-pajpijiet tgħin biex tissimplifika l-proċess tad-disinn, tiżgura l-kompatibilità tal-pajpijiet prodotti minn manifatturi differenti, tnaqqas l-ispejjeż tal-produzzjoni, tadatta għal pressjonijiet u ambjenti tax-xogħol differenti, u kisbu aċċettazzjoni internazzjonali wiesgħa, li tikkontribwixxi għall-istandardizzazzjoni ta 'proġetti ta' inġinerija u prodotti madwar id-dinja.
