ASTM A106 Seamless Pipe

Say ASTM A106 et say estandarten seamless carbon steel pipe ya ibabaga na maslak a managdesinyo no say linya et kaukolan ya mangawit na ambetel a pluido odino gas diad silong na presyon. Ginawa iya parad serbisyo ed atagey a temperatura, say sukat to et unong ed ASME B36.10M, tan nayarin iter na plain odino beveled ya sampot parad welding, bending tan flanging. Diad saray Grade A, B tan C ed ASTM A106, say Grade B so sankarakelan ya uusaren lapud mangiiter na napanmatalkan ya panlalaok na biskeg, ductility tan weldability parad saray steam lines, refinery headers, process piping tan power plant circuits.

• Standard: ASTM A106 / ASME SA106
• Grado: B (wala met so A, C no iyabuloy na proyekto)
• Porma: Anggapoy tahi, ambetel-asumpal odino ambetel-asumpal
• Sampot: Plain end (PE) odino beveled end (BE) parad welding
• Sugat: PANAG-ANDE B36.10M, NPS tan eskedyul tan eskedyul na .

Say grado et nibase ed simpli, kontroladon maong ya carbon-manganese-silicon ya desinyo. Say panangontrol ed P tan S et mamasiansia ed tubo ya na-weld tan malet.

Akin ya importante iya: say carbon so mangiiter na base strength ed grado; Say manganese et ontutulong pian napabiskeg so istruktura na ferrite-pearlite tan napaaligwas toy inkapekder; say silicon et mamaaligwas ed resistensya na scale/oxidation no say tubo et walay awit ton ambetel ya singaw odino process media.

Say grade B et "tatae" ya grado balet mabiskeg la parad maslak ya aplikasyon na tanaman.

Say pangipatalos parad desinyo tan panaggawa: say biskeg na tension so manprotekta ed panagputok tan panag-adyer iran karga; say pamabiskeg so limitasyon sakbay na permanentin deporsyon, nagkalalo la ed importanti parad saray atagey a tuloy{a} say apegpeg a batik; say karukey so mamaseguro a say tubo so nayarin uma{1} linmuyuko, in-weld tan pangiyan na ag-onkupas.

Performance ed High-Temperature Service
Say A106 Grade B et ginetman mansiansia ed serbisyo ed temperatura na metal ya anggad 400-450℃band. Diad sayan lebel say ferrite-pearlite microstructure et mansiansian malet, say silicon et ontulong ed tapew ya ag-onkupas, tan say tubo et mansiansian makaawit na pressure-. Kanian saya so nibaga parad saray boiler feed lines, steam headers, heat-exchanger piping, hot oil service tan refinery utility systems. No duga so PWHT tan welding procedures, say tubo et nayarin onkukurang met ed cyclic service ya anggapoy maples ya pakaandi na inka-tough to.

Parad A106 Say Grade B say rota na panaggawa so aliwan sakey a punto na aksesorya – saya so rason no akin a say tubo so talagan makapankimey ed atagey a temporaryo tan pananesdes. Say tipikal a rota na gilingan parad ag-onkupas ya A106 Grado B ed Tubo na Oktuso et singa saya:

1. Say pampili na billet tan say panangontrol ed chemistry
Say produksyon et onggapo ed pinatey (sigpot ya deoxidized), pino-grain carbon steel billets ya akaabot la ed A106 chemical range. Saya so mangiseguro na abeban P tan S, maong a kalinisan tan pakayarin man-weld. Saray heats et tseken antis ya i-roll pian naabot iray mechanical targets parad Grade B kayari na panagporma tan panag-heat treatment.

2. Pampainit na billet
Saray ballesa so pinainit ed panag-ikot odino panakarhea{0} na hurnoan a hurnoan ed makapakebbiew a temperatura. Importante dia so unipor lan panag-init lapud say ag-inkaparparehon temperatura so pansengegan na bakor{2} na kapal sano natusok so leet.

3. Mainit ya panagtusok (gawa na kakiewan)
Say ambetel a billet et itusok ed sakey a cross-roll odino mandrel piercing mill pian magmaliw a hollow shell. Ditan so pansumpalan na tubo manlapud malet a malimpek ya magmaliw ya anggapoy tahi ya tubo. Say gagala et pian makapawala na shell ya anggapoy central burst tan parepareho so padir ed kaliberliber.

4. Pampaawang tan panag-roll na plug/mandrel
Insan say abot-abot a shell tan ilukot ed tapew na mandel odino gilingan pian onabot ed inka-order a diametro tan kapal na dingding. Nayarin usaren so pigaran panag-roll pian nalinisan so padir tan napaaligwas so tapew. Sayan kundang so manunan sengegan pian magmaliw a malimpek so loob a tapew tan parad pamasiansia ed kapal na bakor ed loob na panag-anos.

5. Pansukat/panagpaabeba na gilingan
Say panagsukat odino panagbabawas na gilingan so mangitarok ed tubo ed unor a OD tan inka-bilog to. Parad saray mas atagey ya eskedyul (mas makapal a dingding), i-adjust iray parok na lukot pian mansiansia so inkakonsenti. Say suston panagsukat dia so mankabaliksan na mas mainomay a panag-welding tan mas maong a tuloy{}} diad pasen.

6. Pan-cool tan panag-ayos .
Kayari na ambetel a panagtrabaho, saray tubo et palemewen ed kontroladon paraan insan ipasa ed sakey a makinan panagpetek. Say inkapeteg et importante parad saray prefabricated spools tan parad automatic welding.

7. Panpainit (no nakaukolan)
Depende ed kabaleg na tubo, say ratio na ibawas tan say pankaukolan na managsaliw, saray tubo et nayarin i-normalize odino i-stress-relieved.

Say pangi-normalize et mamapino ed istruktura na ferrite-pearlite, mamaparakel ed saray kablian to ed karukey tan mamaaligwas ed inka-tough.

Say stress relief et mangekal ed saray stress ya manporma, ya mausar no say tubo et i-welding ed sakey a sistema ya diad saginonor et nanengneng so thermal cycling.
Sayan kontroladon heat treatment so ontutulong ed A106 Grade B pian napansiansia so ductility tan impact resistance to ed hot service.

8. Pansumpal, NDE tan hydrotest
Saray asunson tubo so pinuter ed karukey, saray sampot so akaarap/alakan, tan kada karukey so inspeksion ed pakanengneng parad tapew tan sukat. Insan nasubok so tubo:

• hydrostatic test pian napaneknekan so pressure containment
• eddy-current o ultrasonic NDE pian anapen iray depekto ed loob/tapew
• panagmarka tan panag-abel/pan-ekal parad proteksion .
• Kayari labat na amin na sarayan kundang et say tubo so nibulos a walaan na MTC.

Lapud say interon rota et anggapoy tahi to (anggapoy longitudinal weld), say tubo et walaan na pareparehon pressure resistance ed kaliberliber na interon sirkumperensya – say manunan rason no akin ya say A106 so pinili nen say welded pipe parad serbisyo ed atagey-temperature.

(tipikal a suplay, nayarin ontumbok ed proyekto)

Pian say tubo parad pananesdes tan mainit a serbisyo, say ATM A106 so manutukoy ed inkalapagan iran kakaukolanen ed ASTM A 999. Say tubo ya Tubo so makapangitarya na sigpot a rota na panagsubok:

• Subok ed kada karukey pian napaneknekan so panag-alaan na presyon .
• Say agmakaderal ya panagsukimat (eddy current o ultrasonic) pian nanengneng iray depekto ed tapew tan loob
• Say panag-tension tan inka-malet so mamasubok ed kada petang na asero pian napaneknekan so mekanikal a katutulok .
• Saray subok ed panagpatag / panagyuko pian nipanengneng so inka-ductil
• Say pakanengneng, OD, dingding tan karukey so manseguro pian naseguro so sukat na laman .
• MTCs ed EN 10204 3.1/3.2 parad sigpot ya petang tan test traceability
