I-ASTM A213 T9/T11/T22/T91 Ingxubevange kanye ne-Stainless Tubing yamaBoiler nama-Heat Exchangers

Lapho Lawa Mashubhu Asebenza Kahle Kakhulu (nokuthi Kungani I-Stainless Ngokuvamile Iwina)

Amabhayela kagesi, ama-HRSG, izifudumezi ze-petrochemical, nezishintshisi zokushisa ezihlangene konke kuncike kumashubhu angenamthungo we-ASTM A213/SA213. Uma i-chloride-ithwala i-condensate, imijikelezo evame ukumanziswa, noma izimfuno zenhlanzeko eziqinile ziphezu kwetafula,amamaki angenasici e-austenitic (uchungechunge lwe-TP)ijwayele ukudlula i-chrome-amabanga e-moly ferritic ngenxa yokugqwala okujwayelekile okujwayelekile kanye nokumelana nomgodi, ukuqedwa kwangaphakathi okushelelayo, nokuhlanza kalula.

FAQ

Q1: Ngikhetha kanjani phakathi kwamabanga e-TP angenasici kanye ne-chrome-amabanga e-moly T ngaphansi kwe-ASTM A213/SA213?
A1:Sebenzisa amamaki e-TP kusevisi emanzi/engcolile noma ene-chloride kanye nezidingo zokuhlanzeka; sebenzisa amamaki T uma komile kakhulu-amandla ezinga lokushisa okunyakazayo yiwona oshayelayo.

Q2: Uyini umehluko obonakalayo phakathi kweshubhu ye-SA213 T11, T22, ne-T91?
A2:I-T11 iyisisekelo sezinga lokushisa elimaphakathi, i-T22 yengeza i-creep margin ezingxenyeni ezishisa kakhulu, futhi i-T91 isetshenziselwa umsebenzi ophezulu-weheater we-heater/reheater.

Q3: Yikuphi ukuhlolwa kanye nemibhalo okufanele ngiyicele ishubhu ye-ASTM A213/SA213?
A3:Cela i-hydrotest noma i-NDE test kagesi, 100% eddy current/UT uma kudingeka, i-PMI, kanye ne-EN 10204 3.1 MTC ephelele enamarekhodi okushisa-okwelapha.
