1. Kaja ai hkum tsup ai magam bungli
Dai composite pipe a shinggan bunghku hpe steel pipe hte galaw da nna, kata na lining hpe chromium hpe n-gun ja ai n-gun n-gun n-rawng ai alloy arung arai ni hte galaw da ai. Dai lahkawng gaw kaja ai metallurgical matut mahkai lam hpe hpaw ya ai. Dai gaw, n-gun ja ai arung arai ni a n-gun n rawng ai hte n-gun n rawng ai atsam ni hpe hkam sharang lu ai atsam nga ai sha n-ga, jak rung n-gun grai law ai hte n-gun grai law ai. Dai zawn re ai n-gun atsam hpe ninghkap lu ai atsam grai law ai gaw, shingkyit langai hte matut mahkai na matu yak ai weldability hte bu hpun ai hpe ninghkap ai lam lapran na nhtan shai ai lam hpe hparan ya lu ai, dai hku nna, dai arung arai a bungli galaw ai lam a akyu ni hpe hkum tsup ai hku galaw lu na matu, jai lang ai lam gaw shim lum ai hte kam hpa mai ai.
2. N-gun ja ai hpe ninghkap lu ai
Dai n-gun n-gun n-rawng ai n-gun rawng ai pipe a composite layer gaw, chromium alloy law ai arai langai rai nna, dai structure hta M7C3 zawn re ai hard carbide hta na 45% daram lawm ai. Hpa majaw nga yang, Ka amyu carbide a hkrang gaw rod hkrang bung ai majaw, grai ngang kang ai; dai aten hta, Ka amyu gaw grai law ai (HV1500-1800), n-gun n-gun n-rawng ai layer a microhardness gaw HRC55 a ntsa kaw rai nga ai, dai majaw n-gun n-rawng ai bungli galaw ai lam gaw kaja ai.
3. N-gun ja ai n-gun hpe ninghkap lu ai hte nbung katsi ai hpe ninghkap lu ai
Ka carbide a n-gun hte hkrang masa ni a majaw, n-gun ja ai hka hta Cr lawm ai matrix a majaw, shi gaw n-gun ja ai nbung hpe ninghkap lu ai atsam hte n-gun n-gun hpe ninghkap lu ai atsam nga ai, n-gun ja ai n-gun hpe ninghkap lu ai atsam hte n-gun ja ai shara ni hta n-gun ja ai hpe ninghkap lu ai atsam hte n-gun ja ai shara ni hta n-gun n-gun n-rawng ai hpe madun dan lu ai.
4. Composite hpaji gaw woi awn nna ngang grin nga ai
Dai n-gun n rawng ai pipe hte elbow hpe, sum mat ai foam vacuum suction casting a composite hpaji masa hku nna galaw shapraw ai, ngu ai gaw, F ladat hku nna shapraw ai. Ndai hpaji masa hku nna galaw shapraw ai composite wear-resistant pipe hta lawu na masa ni nga ai:
(1) Hpaji masa gaw asan sha rai nna, bungli galaw ai lam gaw shim lum ai hte galaw shapraw ai lam mung grai law ai. Dai
(2) Ndai hpaji masa a arawn alai ni a majaw, mold galaw ai a dimensional hkrak ai lam gaw grai law ai, n-gun ja ai n-gun atsam hku nna, n-gun ja ai n-gun atsam hku nna, n-gun ja ai hka htung a solid type hpe lang ai majaw, dai arung arai gaw, hkrak ai shadawn shadang hte kaja ai n-gun rawng ai lam ni nga ai.
(3) Alloy n-gun n rawng ai composite pipe ni hte lahput ni hpe F-method vacuum suction casting hpaji masa hku nna law law lang shapraw ai, uniform layout hte ngang grin ai bungli galaw ai lam ni lawm ai. Hpa majaw nga yang, n-gun n rawng ai, n-gun n rawng ai hte n-gun n rawng ai zawn re ai mabyin masa ni n nga na re.
5. Kaja ai thermal shock hpe ninghkap lu ai
Hpa majaw nga yang, composite wist-resistant pipe a kata hte shinggan layer ni a thermal expansion coefficient gaw htap htuk ai, bungli masa ni a matu kata na layer hpe lawan ai hte ayan galai shai ai lam ni nga ai, pipeline system gaw n-gun kaji ai hprawng hkawm ai lam hte tsawm htap ai hkrang hpe aten garai n du yang hkrat sum mat ai shaloi, n-gun n rawng ai.
6. Lang na, jung na hte jai lang na matu loi ai
Alloy composite pipe hte elbow ni hpe flange quick joints (sh) direct welding hte jung mai ai. Composite pipe a anti-shock galaw ai lam grai law ai majaw, n-gun n rawng ai majaw pipe hpe daw mi pat da ai shaloi, shi ra sharawng ai hku nna, n-gun n rawng ai sha, n-gun n rawng ai sha, n-gun n rawng ai sha, n-gun n rawng ai sha, n-gun dat mai ai, dai gaw, garan ginhka, jung da, gram lajang na matu grai shim lum ai.
