ASTM A106 n-gang n-gang ai hka htung

ASTM A106 gaw, line hpe n-gun npu hta n-gun ja ai ntsin (sh) gas hpe htaw ra ai shaloi, designer law malawng tsun da ai, n-gun n rawng ai carbon steel pipe re. Dai hpe n-gun ja ai-hpring tsup ai magam bungli a matu galaw da ai rai nna, ASME B36.10M hte maren shadawn shadang tawn da ai rai nna, n-gun n rawng ai (sh) n-gun n rawng ai npawt nhpang ni hpe shinggrup na matu, shinggrup na matu hte shinggrup na matu n-gun n rawng ai jahtum ni hte jaw mai ai. ASTM A106 hta Grade A, B hte C ni hta, Grade B hpe grau jai lang ai gaw, hka htung line ni, hka htung baw ni, process piping hte power plant circuit ni a matu kam mai ai n-gun, n-gun n-gun hte weldability ni hpe kayau kaya jaw ya ai majaw re.

• Madang: ASTM A106 / ASME SA106
• Grade: B (project ahkang jaw yang A, C hpe mung mai lang ai)
• Form: Seamless, katsi ai-ngut sai (sh) katsi ai-ngut sai
• Hpang jahtum: Weld galaw na matu n-gun n rawng ai (PE) shing nrai, n-gun n rawng ai (BE)
• Shadawn shadang ni: ASME B36.10M, NPS hte aten ladaw - hpe madung tawn ai

Ndai grade hpe asan sha, kaja wa-hkang lu ai carbon–manganese–silicon hkrang hpe madung tawn nna galaw ai re. P hte S hpe hkang ai gaw pipe hpe weldable hte ngang kang hkra galaw ya ai.

Ndai lam hpa majaw ahkyak ai: carbon gaw grade hpe shi a npawt nhpang n-gun jaw ai; manganese gaw ferrite–pearlite hkrang hpe ngang grin hkra galaw ya nna, ngang kang ai lam hpe grau kaja hkra galaw ya ai; silicon gaw pipe hta nbung n-gun (sh) process media hpe htaw ai shaloi scale/oxidation hpe ninghkap lu ai atsam hpe jat ya ai.

Grade B gaw "middle" grade rai tim, hpun law malawng lang na matu n-gun ja sai.

Design hte galaw shapraw na matu lachyum shaleng ai lam: tensile n-gun gaw, gap hkat ai hte axial load ni hpe makawp maga ya ai; yield n-gun gaw, prat tup n-gun n rawng shi ai aten na shadawn sharam rai nga ai, grau nna -pressure kaba ai run ni a matu ahkyak ai; elongation gaw pipe hpe field-bent galaw nna, n-gun n rawng ai sha jung lu na matu madi shadaw ya ai.

-Katsi ai Magam Bungli hta bungli galaw ai lam
A106 Grade B gaw 400–450℃band du hkra n-gun rawng ai magri n-gun rawng ai shara ni hta bungli galaw nga na matu yaw shada ai. Ndai madang hta ferrite–pearlite n-gun kaji gaw ngang grin nga ai, silicon gaw ntsa lam hpe n-gun n rawng hkra karum ya ai, pipe gaw shi a n-gun-hkap la lu ai atsam hpe n-gun rawng hkra galaw ya ai. Dai majaw, boiler n-gun jaw ai line ni, steam header ni, heat-galai ai piping ni, sau n-gun ja ai service hte refinery utility system ni a matu masat da ai. PWHT hte welding ladat ni hpe hkrak hkra galaw yang, pipe gaw lawan ladan n sum mat ai sha, cyclic service hta mung hkawm lu ai.

A106 Grade B a matu galaw shapraw ai lam gaw accessory point n re – dai gaw pipe gaw nbung katsi ai hte n-gun kaba ai shara hta teng sha bungli galaw lu ai a lam re. Octal Pipe kaw na n-gun n rawng ai A106 Grade B a matu n-gun rawng ai hka htung lam langai gaw ndai zawn rai nga ai:

1. Billet lata ai lam hte chemistry hpe hkang ai lam
A106 tsi mawan n-gun hpe hkan sa sai sat kau hkrum ai (hkum tsup ai hku n-gun n rawng ai), n-gun n rawng ai-n-gun rawng ai carbon steel billets ni kaw nna galaw hpang ai. Ndai hku galaw ai gaw P hte S n law ai, san seng ai lam kaja ai hte weldability kaja ai hpe madi shadaw ya ai. Heats ni hpe n-gun n-jaw shi yang jep yu ai majaw Grade B a matu mechanical targets ni hpe form galaw nna heat treatment galaw ngut ai hpang du lu na re.

2. Billet hpe katsi shangun ai
Billets ni hpe shinggrup ai (sh) hkawm sa ai-beam wan wut ai wan n-ga hta, shinggrup/htu ai nbung katsi ai shara de du hkra katsi shangun ai. Ndai shara hta n bung ai katsi ai lam gaw ahkyak ai, hpa majaw nga yang, n bung ai katsi ai lam gaw, billet hpe htu ai shaloi bunghku-n-gun galai shai wa na re.

3. Hka lum ai hku htu ai (hollow galaw ai)
Dai n-gun ja ai billet hpe cross-roll (sh) mandrel htu ai jak ntsa hta htu nna, n-gup n-ga n-gun n rawng ai shell byin hkra galaw ai. Ndai shara kaw pipe gaw ngang kang ai grup yin kaw nna n-gun n rawng ai pipe de gale mat wa ai. Yaw shada ai lam gaw, lapran n-gun n rawng ai sha, grup yin bunghku langai sha nga ai shell hpe galaw shapraw na matu re.

4. Galu ai hte plug/mandrel hpe shinggrup ai
Dai hpang, dai n-gup magap hpe galu shangun nna, mandrel (sh) plug mill ntsa de shinggrup nna, masat da ai diameter hte bunghku n-gun hte grau ni htep hkra galaw ai. Bunghku hpe grau kaja hkra galaw na matu hte ntsa hpe grau kaja hkra galaw na matu rolling stand law law hpe lang mai ai. Ndai lahkam gaw kata na npu hpe n-gun ja hkra galaw na matu hte bunghku n-gun hpe hkam sharang lu ai daram tawn da na matu ahkyak ai.

5. Sizing/shayawm ai hka htung
Sizing (sh) shayawm ai mill gaw pipe hpe hpang jahtum na OD hte grup yin de du hkra woi sa wa ai. Grau tsaw ai aten ladaw ni (bunghku kaba ni) a matu, shingjawng ai lam hpe n-gun n rawng hkra gram lajang da ai. Ndai kaw hkrak ai sizing ngu ai gaw, welding galaw na matu loi ai hte shara kaw grau hkrak hkra-up ai lachyum re.

6. Katsi ai hte dingyang galaw ai .
Katsi ai hku bungli galaw ngut ai hpang, pipe ni hpe hkang lu ai ladat hte katsi shangun nna, dingyang galaw ai jak hku nna lai shangun ai. Dingyang ai lam gaw, shawng nnan galaw da ai spool ni a matu hte, shi hkum shi welding galaw na matu ahkyak ai.

7. Hka lum ai hku tsi lajang ai (ra ai hku)
Pipe kaba ai, shayawm ai ratio hte mari ai wa ra sharawng ai hta hkan nna, pipe ni hpe normalize galaw mai ai (sh) stress-relief galaw mai ai.

Normalizing gaw ferrite–pearlite hkrang hpe grau kaja hkra galaw ya nna, galu kaba ai lam hta atsam marai ni hpe rap ra hkra galaw ya ai hte ngang kang ai lam hpe grau kaja hkra galaw ya ai.

Stress relief gaw byin pru wa ai stress ni hpe shapraw kau ya ai, dai gaw hpang de thermal cycling hpe mu lu na system langai mi de pipe hpe weld galaw na rai yang akyu nga ai.
Ndai hkang lu ai katsi ai lam gaw A106 Grade B hpe katsi ai magam bungli hta shi a ductility hte hkra machyi ai lam hpe hkam sharang lu hkra karum ya ai lam rai nga ai.

8. Hpang jahtum galaw ai, NDE hte hka chyam dinglik ai
Hpang jahtum na pipe ni hpe galu ai hku gang je kau nna, jahtum ni hpe face/beveled galaw nna, galu ai langai hte langai hpe ntsa lam hte dimensional hkrak ai lam hpe myi man hte jep yu ai. Dai hpang, pipe hpe chyam yu ai:

• n-gun hpe hkang lu ai hpe sakse madun na matu hydrostatic chyam dinglik ai
• eddy-ya aten (sh) ultrasonic NDE hpe kata/ntsa n kaja ai lam ni hpe tam na matu
• makawp maga na matu masat kumla hte ka-up/varnish
• Ndai lahkam yawng ngut ai hpang she MTC hte pipe hpe shapraw kau ai.

Hpa majaw nga yang, lam ting gaw n-gun n rawng ai majaw (longitudinal weld n nga ai), pipe gaw grup yin ting grup yin hta n-gun langai sha re ai n-gun hpe ninghkap lu ai – madung lam gaw A106 hpe welded pipe hta grau nna -temperature service galaw na matu lata la ai lam re.

(madung hku nna jaw ya ai, bungli masing hpyi shawn ai hpe hkan sa mai ai)

Pipe hpe pressure hte hot service a matu hkap la mai hkra galaw na matu, ASTM A106 gaw ASTM A999 hta lawm ai madung ra kadawn ai lam ni hpe tsun mayu ai. Octal Pipe gaw chyam dinglik ai lam hpe tup hkrak jaw ya lu ai:

• Hydrostatic chyam dinglik ai lam gaw galu kaba ai lam hpe sakse madun na matu
• N jahten sharun ai jep joi ai lam (eddy current (sh) ultrasonic) gaw ntsa hte kata na n kaja ai lam ni hpe jep yu na matu
• Hpaji hte maren hkan sa ai lam hpe jep yu na matu n-gang a katsi ai hta n-gun hte ngang kang ai hpe chyam yu ai
• Ductility hpe madun na matu n-gun n rawng ai / shinggrup ai chyam dinglik ai lam ni
• Dimensional bung ai hpe kam na matu myi hte mu lu ai, OD, bunghku hte galu ai hpe jep yu ai
• MTCs ni gaw EN 10204 3.1/3.2 de hkum tsup ai katsi ai hte chyam dinglik ai lam hpe hkan tam lu na matu
