ASTM A179 / ASME SA179 Diphaephe tša Phapantšho ya Mogote - BLOG

Matseno

ASTM A179 / ASME SA179 hlalosa seamless, batang - thaloa, tlaase - khapone tšepe diphaephe boenjiniere bakeng sa bokgoni mocheso phetiso le ka tšeptjoang bopa tshebetso. Ka bonnyane-kago ya lebota le taolo ye e tiilego ya tšhipi, diphaephe tše di šomišwa kudu ka go diphapantšho tša phišo le dikhondense go ralala le diintasteri tša go hlwekiša, dikhemikhale tša petroleum, le tša mohlagase.Octal Pipe phepelo A179 / SA179 diphaephe bakeng sa lefatše EPC le thepa fabricators, go thekga bobedi diphaephe tše di se nago selo le dikopano tša go koba tša U-.

Sebopego sa Dikhemikhale

Tšweletšo & Kalafo ya Mogote

Diphaephe tša ASTM A179 / ASME SA179 di tšweletšwa ka tshepedišo ya mošomo ya tšweletšo ye e se nago selo ye e laolwago yeo e latelwago ke go thala ka go tonya ka go nepagala go fihlelela kgotlelelo ya mahlakore ye e tiilego le bokagodimo bjo bo boreledi bja ka gare bakeng sa bokgoni bjo bo kaonafetšego bja phetišetšo ya phišo-.

Tshepedišo ya tšweletšo ye e se nago selo

Hollow billet → phunya → chesang bopa → multi-feta batang thalong

Taolo ya dimenšene e netefatša gore nyakego ya fasefase-lebotong e fihlelelwa ka nepagalo

Go thala ka go tonya go godiša phetho ya bokagodimo le bohlweki bja ka gare-bohlokwa go fokotša go šilafala ka gare ga diphapantšho tša phišo

Kalafo ya mafelelo ya phišo

Ka morago ga go feta ga mafelelo ga go tonya-go goga, diphaephe di alafša ka phišo kaE kgolo go feta goba e lekanago le 1200℃F ( E kgolo goba e lekanago le 650℃) .go:

Imolla dikgateletšego tša mašaledi tšeo di bakwago ke mošomo wa go tonya
Tsosolosa ductility hlokahala bakeng saU- koba le katoloso ya tubesheet
Kaonafatša go tsepama ga sebopego sa nako ye telele ka fase ga merwalo ya phišo ya modikologo

Boemo bja bokagodimo & go lokišetša

E filwesekala - mahalago boloka tshepedišo ya go fiša ye e loketšego
Mafelelo kehlwekile le burr-free, netefatsa weldability tšepahalang kapa katoloso mochine nakong kopano
Taolo ye ya tšweletšo le ya tšhipi e thuša go netefatša bophelo bjo botelele bja tirelo, go botega ga sebopego, le go hloma mo go bolokegilego ka gare ga diphuthelwana tša diphapantšho tša go ba le segokanyipalo sa godimo -.

Tlhahlobo & Teko

Go ya ka ASTM A179 le ASTM A450/A450M:

Ntho ya Tlhahlobo	Morero
Teko ya hydrostatic goba ya NDE	Leak-netefatšo ya go gagamala
Teko ya go batalatša	Soundness le ductility hlahloba
