Sanitary double-tubesheet n-gun galai ai jak ni gaw, malu masha, tsi mawan, hte shinggyim nga pra masa zawn re ai san seng ai lam grai law ai bungli ni a matu galaw da ai, grai kaja ai n-gun galai ai arung arai ni rai nga ai. Shanhte a madung hkrang gaw, n-gun ja ai san seng ai lam hte n-gun ja ai san seng ai lam ni hpe hkan sa ai sha n-ga, media hpe cross-n san seng ai lam hpe hkrak hkra pat shingdang lu na matu, garan ginhka ai pat shingdang ai lam hpe jat bang ai, double-tubesheet hkrang hpe jai lang ai.
Ndai nbung galai shai ai jak a double-tubesheet hkrang gaw kata hte shinggan tubesheet lahkawng lawm nna, lapran kaw isolation chamber langai mi nga ai. Ndai gaw shell hte tube maga na media leak ni hpe aten dep - yu reng lu shangun ai. Kata na hka htung kata kaw hka pru wa yang, kaga maga de hkrak sha awu asin byin ai hta, media gaw isolation chamber de shang wa ai majaw, process safety hpe lu la mai ai. Dai arung arai gaw, 316L n-gun n rawng ai n-gang (sh) dai hta grau tsaw ai -madang n-gun rawng ai n-gang ni rai nna, ntsa maga de Ra Less (sh) 0.4μm hte maren sha rai nna, GMP (Kaja ai Hpaga Lam) hte FDA (US Lusha hte Tsi Hkringmang Dap) madang ni hpe hkan sa ai.
Hpaji masa hte seng nna, san seng ai double-tubesheet nbung galai shai ai jak ni gaw, gasket hte seal ni kaw na awu asin byin wa na hpe yeng seng kau lu na matu, hkum tsup ai hku shinggrup da ai (sh) argon arc welding matut mahkai lam ni hpe jai lang ma ai. Shi a lwi ai lam hpe hkrang shapraw ai gaw, nbung laru hpe grau kaja hkra galaw ya ai, htunghking hku lang ai single-tubesheet jak ni hte shingdaw yang, nbung hpe htawt sit ai atsam hpe 15%-20% jat ya ai. CIP (san seng ai-- shara) hte SIP (sterilization-- shara) ni hpe mung galaw ya ai. Kalang lang jai lang ai lam ni hta, hkaulan mam arung arai ni hpe pasteurization galaw ai, tsi htu ai shaloi nbung katsi ai hpe hkang lu ai, san seng ai tsi ni hpe katsi/katsi shangun ai lam ni lawm ai.
Hkringmang daju a matu, double-tubesheet structure gaw, garan ginhka nna jep joi ai lam hpe loi shangun ai, isolation chamber kata na leak hpe mu tam ai gaw, byin mai ai hkrat sum lam ni hpe tau hkrau sadi jaw ya ai majaw, n-gun yawm mat na masa hpe shayawm ya lu ai. Tsi hte malu masha hpaga lam ni gaw, hkan sa ai lam hte akyu rawng ai lam hpe grau nna ra sharawng ai majaw, san seng ai double-tubesheet heat exchangers ni gaw ahkyak ai bungli galaw ai arung arai ni a matu ra sharawng ai hparan ladat langai byin wa nga ai. Hpaji masa ni gaw modular design, hpaji rawng ai hku yu reng ai lam, n-gun lang ai lam hpe shayawm ai lam ni hpe madung tawn ai.
