LSAW Welded Pipe
Longitudinally Submerged Arc Vuam Yeeb Nkab yog subdivided rau hauv UOE, RBE, JCOE steel yeeb nkab raws li nws txoj kev sib txawv. Longitudinal highfrequency welded steel yeeb nkab muaj cov yam ntxwv ntawm cov txheej txheem yooj yim thiab ceev nruam ntau lawm, thiab tau siv dav hauv kev tsim kho pej xeem, petrochemical, lub teeb kev lag luam thiab lwm yam haujlwm. Feem ntau yog siv los thauj cov kua dej uas tsis tshua muaj siab lossis ua rau hauv ntau yam engineering thiab cov khoom lag luam teeb.
Kev piav qhia ntawm cov txheej txheem tseem ceeb ntawm cov loj - txoj kab uas hla ncaj seam welded yeeb nkab:
1. Phaj tshuaj xyuas: Tom qab cov hlau phaj siv los tsim cov loj - txoj kab uas hla submerged arc welded ncaj seam steel yeeb nkab nkag mus rau hauv cov kab ntau lawm, tag nrho cov phaj ultrasonic tshuaj xyuas yog thawj zaug;
2. Ntug milling: ob npaug -sab milling ntawm ob npoo ntawm cov hlau phaj los ntawm lub tshuab milling kom ua tiav cov phaj dav, phaj ntug parallelism thiab bevel puab;
3. Pre-bending: Siv lub tshuab ua ntej- dabtsi yog khoov los ua ntej- khoov ntug ntawm lub rooj tsavxwm kom lub ntug ntawm lub rooj tsavxwm muaj qhov nkhaus uas ua tau raws li qhov yuav tsum tau ua;
4. Kev sib sau: Ntawm JCO txoj kev tshuab, thawj ib nrab ntawm lub pre- bent steel phaj yog nias rau hauv "J" zoo los ntawm ntau kauj ruam, thiab tom qab ntawd ib nrab ntawm cov hlau phaj tseem khoov thiab nias rau hauv "C" duab, thiab thaum kawg qhib qhib yog tsim "O" duab
5. Ua ntej- vuam: Koom nrog cov kav hlau txuas txuas txuas txuas txuas thiab siv cov roj tiv thaiv vuam (MAG) rau kev txuas txuas ntxiv;
6. Internal welding: siv longitudinal multi-wire submerged arc welding (mus txog plaub lub xov hlau) los txuas rau sab hauv ntawm cov yeeb nkab ncaj seam steel;
7. Sab nraud welding: siv longitudinal multi-wire submerged arc vuam rau welding nyob rau sab nraud ntawm longitudinal submerged arc welded steel yeeb nkab;
8. Ultrasonic soj ntsuam I: 100% kev soj ntsuam ntawm lub puab thiab sab nrauv welds ntawm longitudinally welded steel yeeb nkab thiab cov ntaub ntawv hauv paus ntawm ob sab ntawm lub vuam;
9. X-ray tshuaj ntsuam I: 100% X-ray industrial TV tshuaj xyuas ntawm cov welds sab hauv thiab sab nrauv, siv cov duab ua haujlwm los xyuas kom meej qhov rhiab heev ntawm qhov tsis zoo;
10. Txoj kab uas hla: nthuav tag nrho ntev ntawm cov submerged arc welded ncaj seam steel yeeb nkab los txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho qhov kev faib tawm ntawm cov kev ntxhov siab sab hauv ntawm cov yeeb nkab steel;
11. Hydraulic test: Cov kav hlau txuas tau raug tshuaj xyuas ib qho los ntawm ib qho ntawm lub tshuab kuaj hydraulic kom ntseeg tau tias cov yeeb nkab steel ua tau raws li qhov kev sim siab xav tau los ntawm tus qauv. Lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia;
12. Chamfering: txheej txheem cov yeeb nkab kawg ntawm cov yeeb nkab steel tsim nyog kom tau raws li qhov xav tau cov yeeb nkab kawg zawj loj;
13. Ultrasonic tshuaj xyuas Ⅱ: Ua ultrasonic soj ntsuam ib zaug ib zaug los xyuas qhov ua tau tsis xws luag ntawm longitudinally welded steel yeeb nkab tom qab txoj kab uas hla expansion thiab dej siab;
14. X-ray tshuaj ntsuam Ⅱ: X-ray industrial TV tshuaj xyuas thiab ua yeeb yaj kiab ntawm cov yeeb nkab kawg welds ntawm cov yeeb nkab steel tom qab kev nthuav dav thiab kev ntsuas hydraulic;
15. Tube kawg magnetic particle soj ntsuam: ua qhov kev tshuaj xyuas no kom pom qhov kawg ntawm lub raj;
16. Anti-corrosion thiab txheej: Tsim nyog cov kav dej steel yog tiv thaiv- xeb thiab txheej raws li cov neeg siv khoom xav tau.
