Welded flange ngu ai gaw, garan mai ai matut mahkai lam rai nna, bolt preload hku nna gaskets ni hpe shinggrup nna, shinggrup da ai lam hpe lu la ai. Shi a madung tara gaw, n-gun n rawng ai shara ni hpe jahpring na matu hte n-gun n rawng ai shara ni hpe pat shingdang na matu, flange sealing ntsa lapran na gasket deformation hpe jai lang ai lam lawm ai. .
Matut mahkai ladat
Flange disc lahkawng hpe bolt ni hte shinggrup da nna, shanhte a lapran hta n-gup magap (ga shadawn, graphite, magri-hkum hkrang n-gup magap, etc.) hpe sandwich galaw da ai. Dai preload gaw gasket hpe shinggrup nna, flange sealing ntsa na n tara ai lam ni hpe n-gun n rawng ai shara ni hpe jahpring ya ai majaw, seal byin wa ai. .
Sealing masa lam ni
Preload Stage: Bolt hpe preload galaw ai shaloi, gasket hpe preload galaw ai n-gun hta grau kaba ai (sh) maren sha re ai hpe lu la ra ai.
Operating Stage: Media n-gun npu hta, ngam nga ai n-gun gaw bungli galaw ai sealing n-gun hta grau kaba ai (sh) maren sha rai ra ai. .
Weld galaw da ai flange amyu ni
Butt-Weld Flange: N-gup magap hte matut mahkai ai lam, asan sha galaw da ai, n-gun n law ai (0.6-4.0MPa) a matu htuk manu ai. .
Socket Weld Flange: Butt weld matut mahkai ai lam, n-gun kaba (1-25MPa) hte ahkyak ai bungli ni a matu htuk manu ai. .
Laika shawk shawn ai lam ni
Pipeline hte arung arai ni hpe matut mahkai na matu, tsi mawan, tsi mawan, hte kaga hpaga lam ni hta law law lang lang ai, kam mai ai hku shinggrup da ai hte garan ginhka lu ai atsam lahkawng yan hpe jaw ya ai.
