2. 300 Series n-gun n rawng ai hpri pipe ni: Kaja dik htum galaw lu ai atsam, gat lawk madung
300 series gaw austenitic stainless steel mung rai nna, ya aten hta grau nna jai lang ai series rai nna, ngang grin ai mying kaba ai. Shi gaw tsep kawp non-magnetic rai nna, n-gun n rawng ai, n-gun ja ai, hte welding galaw ai atsam ni hpe rap ra ai hku hkam la lu ai, shi a laksan grade ni hpe grai yaw shada ai.
1. 304 N-gun n rawng ai hpri Pipe (Madung masat masa)
Ndai gaw mung shawa ni a myit sawn ai lam hta, classic dik htum malu masha-grade stainless steel rai nna, hpaji masa hku nna rap ra ai chromium hte nickel ratio, kaja ai-rounded yawng hkra galaw lu ai, hka htung n-gun hpe grai kaja hkra ninghkap lu ai, n-gun n-gun n-rawng ai shara ni hta oxidation hpe grai kaja hkra ninghkap lu ai. Process galaw na matu, bend galaw na matu, weld galaw na matu mung grai shim ai.
304 stainless steel pipe ni gaw mung shawa hte bungli galaw ai shara law malawng hpe shinggrup da ai: lu hka pipe ni, malu masha galaw shapraw ai arung arai pipe ni, mare kata na hka jaw ai hte hka lim ai jak ni, ordinary machine, archite. etc. Nta kata hte shingra tara hku katsi ai shinggan makau grup yin ni hta lang mai ai, engineering mari la na matu madung shawng-lata ai arung arai mung rai nga ai.
2. 304L N-hprang n-gang Pipe (Carbon n law ai gram lajang ai hkrang)
304 hpe madung tawn nna, carbon dat hpe shayawm kau ai. Shi a madung akyu gaw, grau n-gun ja ai welding galaw lu ai majaw, welding galaw ngut ai hpang, intergranular corrosion byin wa na masa n nga ai, weld ni gaw loi loi hte n-gun n rawng ai, n-gun n rawng ai.
Piping bungli masing kaba ni, hka htung tank piping ni, hte galu kaba ai shara -site welding galaw ra ai pipeline ni a matu htuk manu ai majaw, industrial welding mabyin masa ni a matu grau ra sharawng ai lata la ai lam rai nga ai.
3. 316 hte 316L n-gun n rawng ai n-gang n-gang pipe ni (hpyen n-gun grai ja ai-hkam sharang lu ai version ni)
Dai lahkawng yan hta molybdenum hpe jat bang da ai, dai gaw 304 hte shingdaw yang madung shai hkat ai lam rai nga ai.Molybdenum gaw chloride ions, sau htu ai, acid{1}}base n-gun hpe ninghkap lu ai atsam hpe grai jat ya ai majaw, n-gun hpe ninghkap lu ai atsam gaw 304 hta grau kaja ai, manu mung dai hte maren grau tsaw ai.
Dai ni hta 316L gaw low-carbon version rai nna, welding galaw ngut ai hpang grau kaja ai ngang grin lam hpe jaw ya ai. Ndai zawn re ai pipe ni gaw panglai hkin-gau ginra ni, panglai hpaji, panglai hka htaw sa ai lam, tsi mawan, tsi mawan kaja ni, hka n san seng ai hka hpe jasan jaseng ai lam, hte kaga grai n hkru n kaja ai makau grup yin ni a matu laksan hku nna htuk manu ai rai nna, tsi mawan ni hte high-end sanitary ware ni hta mung law law lang lang lang ai. Salt (sh) chlorine lawm ai masa hta, 304 hpe n mai lang ai shara ni hta, 316L hpe madung hku nna lata la mai ai.
4. 321 N-gun n rawng ai n-gang Pipe (N-gun ja ai shara ni a matu laksan galaw da ai)
Titanium elements ni hpe dai arai hta bang da ai, madung gaw n-gang n-gang hpe ngang grin hkra galaw na matu re. 450℃kaw nna 850℃du hkra n-gun ja ai shara ni hta ngang grin ai bungli galaw lu ai, n-gun ja ai oxidation hte intergranular corrosion hpe grai hkam sharang lu ai.
Acid hte alkali hpe ninghkap lu ai atsam hta grai n-gun n rawng ai raitim, n-gun ja ai -n-gun hpe ninghkap lu ai atsam hpe madung tawn nna, boiler pipeline, n-gun galai shai ai jak, hte industrial n-gun ja ai -n-gun ja ai wan n-ga hpe htaw sa ai pipeline ni hta grau nna jai lang ai, kaga n-gun ja ai -n-gun ja ai jai lang ai lam ni hta mung jai lang ai.
3.400 Series n-gun n rawng ai hpri hka htung ni: Ferritic / Martensitic, shingra tara hku nna n-gun rawng ai
Non-magnetic 300 series hte n bung ai sha, 400 series n-gun n rawng ai n-gang gaw, magnetic hkrai rai nna, nickel n lawm ai, manu n law ai, bungli galaw ai lam hpe madung tawn nna, jai lang ai lam kaba lahkawng hku garan nna galaw ai.
1. 430 N-gun n rawng ai n-gang Pipe (Mawn sumli ai lam hte shani shagu lang na matu ra sharawng ai)
Shi gaw ferritic stainless steel hta lawm ai, ntsa lam hpe kaja ai hku hpraw hkra galaw ya lu ai, n-gun n rawng ai, manu n hkrat ai, manu n hkrat ai. Shi a n-gun gaw 304 hta n-gun kya ai raitim 201 hta grau kaja ai.Shi hpe shat gawk na arung arai ni, jak rung arung arai ni, shinggyim masha ni a mawn sumli ai pipe ni, nitric acid n-gun n law ai arung arai ni hta lang ai. N-gun kaba n ra ai masa ni a matu htap htuk ai, hkrang bung sumla hte madung n-gun n rawng ai hpe makawp maga ai lam hpe madung tawn ai.
2. 409, 410, 420 N-hprang n-gun n-rawng ai n-gang Pipe ni (Katsi ai-hkap la lu ai, N-gun ja ai -Version ni)
409 gaw madung hku nna katsi ai hpe ninghkap lu ai atsam hpe ahkyak shatai nna, mawdaw n-gun dat pru ai pipe ni hte bungli galaw ai shara ni hta n-gun n law ai-katsi ai wan n-gun dat pipeline ni hta law law lang lang ai; 410 hte 420 gaw martensitic stainless steels rai nna, carbon grau law ai, n-gun ja ai lam hte n-gun ja ai lam hpe n-gun jat ya lu ai, raitim shanhte a n-gun ja ai lam hpe ninghkap lu ai atsam gaw shadawn shadang sha rai nga ai.
