Lub hauv paus ntawm kev saib xyuas niaj hnub rau longitudinally welded steel kav yog nyob rau hauv kev saib xyuas kev ncaj ncees ntawm longitudinal weld, qhov xwm txheej ntawm cov tshuaj tiv thaiv -corrosion txheej, thiab kev ua haujlwm tsis ua haujlwm. Kev tshuaj xyuas tsis tu ncua, tu, tiv thaiv kev ntsuas, thiab kho qhov tsis xws luag yog qhov tseem ceeb los tiv thaiv kev tawg tawg lossis tawg los ntawm kev ntxhov siab.
Kev soj ntsuam tshwj xeeb Weld: Ua txhua lub hlis twg (lossis txhua hli hauv qhov chaw hnyav) kev tshuaj xyuas qhov ntev ntawm cov welds los xyuas cov kab nrib pleb, undercut, lossis corrosion. Rau cov kav dej uas muaj zog los yog qhov tseem ceeb, ua kev tshuaj xyuas txhua xyoo- koom nrog kev kuaj ultrasonic lossis magnetic particle- txhawm rau txheeb xyuas qhov tsis muaj fusion lossis qaug zog tawg, nrog rau kev tsom mus rau qhov kub ntawm qhov vuam - thaj tsam cuam tshuam.
Kev Tiv Thaiv - Corrosion Coating Maintenance: Tshawb xyuas cov khoom tiv thaiv sab nraud -corrosion coatings (xws li 3PE, galvanizing) rau tev lossis khawb. Yog tias kuaj pom muaj kev puas tsuaj, ntxuav, zom, thiab rov ua dua qhov chaw nrog cov khoom sib xws hauv 48 teev; xyuas kom meej tias cov hlau liab qab yog nruj me ntsis tiv thaiv los ntawm kev sib cuag nrog corrosive media.
Kev Tu thiab Tiv Thaiv Ntog: Tsis tu ncua tshem cov roj, vuam spatter, thiab cov plua plav ntau. Siv cov tshuaj ntxuav tshwj xeeb rau stainless hlau los tiv thaiv chloride ion corrosion; khaws cov pa roj carbon steel kom qhuav thiab ua kom zoo- tso cua kom tsis txhob muaj cov dej noo ntau ntxiv uas ua rau cov tshuaj tiv thaiv electrochemical.
Kev Saib Xyuas Kev Ua Haujlwm: Saib xyuas kev hloov pauv hauv lub siab, kev co txawv txav, thiab nruab nrab kev sib raug zoo. Tiv thaiv overpressure, dej rauj, los yog corrosive media los ntawm kev ua kom qaug zog tsis ua hauj lwm nyob rau hauv longitudinal welds; tshuaj xyuas cov kev txhawb nqa thiab cov hangers kom ntseeg tau tias lawv tsis xoob, uas tuaj yeem raug welds rau kev ntxhov siab ntxiv.
Cia thiab Kev Tswj Ib puag ncig: Khaws cov kav hlau tsis muaj zog hauv tsev; Sab nraum zoov stacking yog nruj me ntsis txwv tsis pub. Rau kev ua haujlwm ntev -lub sijhawm tsis ua haujlwm, siv cov pam pam nitrogen lossis tiv thaiv- xeb roj los tiv thaiv oxidation ntawm cov phab ntsa sab hauv.
