Khoom Taw qhia

321 pre fabrication ntawm cov yeeb nkab spoolsyog titanium -stabilized austenitic stainless hlau. Lub hauv paus muaj pes tsawg leeg yog qhov tseem ceeb 304 (18Cr-8Ni) nrog me me ntxiv ntawm titanium, feem ntau 5 × (C + N) yam tsawg kawg nkaus, uas ua haujlwm tawm mus rau kwv yees li 0.15-0.40% Ti nyob ntawm cov ntsiab lus carbon. Lub titanium ua ib txoj hauj lwm tseem ceeb: nws khi cov pa roj carbon li titanium carbide ua ntej chromium tuaj yeem tsim chromium carbide ntawm cov ciam teb.

321 vs 321H: tsis txhob sib tov

Qib	Cov pa roj carbon ntau	Hom kev siv
TIAB SA 321	0.08% max	General elevated kub
TP 321 H	0.04-0.10% (tswj min)	Kev kub siab - kev pabcuam kub ib qho ASME Code Case

321H muaj kev tswj hwm cov ntsiab lus tsawg kawg nkaus kom ntseeg tau tias nce siab -kub creep zog. Qib H yog qhov feem ntau cov kev qhia tshwj xeeb hu rau saum 540 degree. Los ntawm kev tsim qauv, 321H welds txawv me ntsis - cov pa roj carbon ntau dua txhais tau tias muaj kev pheej hmoo ntawm carbide nag lossis daus ntau dua yog tias tsis muaj kev ruaj ntseg, uas ua rau muaj kev cuam tshuam ntau dua rau cov vuam tsis zoo.

Dab tsi yog Prefabricated Pipe Spool?

Cov yeeb nkab spool yog tus kheej- ntu ntawm cov kav dej uas muaj cov kav dej nyoos txiav kom ntev, welded rau qhov tsim nyog fittings xws li lub luj tshib, tees, reducers, thiab tiav nrog flanges rau ntsia liaj qhov rooj - nce installation ntawm - site.

Es tsis txhob welding cov complex configurations siab mus rau ib tug kev tsim scaffold, tag nrho cov sub-sembly yog pre-engineered thiab ua nyob rau hauv ib tug tshwj xeeb fabrication khw. Thaum ua tiav, cov qauv ua tiav no raug xa ncaj qha mus rau thaj chaw rau poob - hauv bolting.

Ntawm -Site vs. Off-Site Fabrication

Kev tsim cov kav dej hauv thaj teb ua rau cov phiaj xwm muaj kev cuam tshuam rau huab cua qeeb, lub sijhawm ua haujlwm nruj, thiab kev txwv tsis pub nkag. Hloov mus rau kev tawm ntawm -site khw prefabrication muaj qhov zoo sib xws:

Qhov xwm txheej	Ntawm -Site Field Fabrication	Tawm -Site Shop Prefabrication
Environmental Control	Tawm rau cua, av noo, thiab nag, pheej hmoo weld porosity.	Ua kom tiav, cov khw muag khoom climatized kom ntseeg tau cov roj tiv thaiv pristine.
Vuam Ergonomics	Tsau - txoj hauj lwm vuam, yuav tsum tau hla dhau kev nyuaj.	Kev siv cov yeeb nkab tsis siv neeg rotators kom zoo ib yam - txoj hauj lwm yob vuam.
Kev Tswj Xyuas Zoo & Kev Xeem	Kev thauj cov neeg ua haujlwm radiography lossis hydro- kuaj cov rigs rau cov scaffolds siab yog pheej hmoo thiab qeeb.	Hauv -tsev NDT bays rau X-ray sai, dye penetrant, thiab hydrotesting.
Project Logistics	Cov nqi ua haujlwm siab, ntau qhov chaw scaffolding footprints, thiab qhov chaw congestion.	Parallel processing; spools yog tsim thaum lub hauv paus chaw ua hauj lwm yog poured.
