ASTM A252 Gulu la 3 Pipe PileASTM A252 Gulu la 3 Mulu wa Chitoliro

Milu ya mapaipi a ASTM A252 Gulu la 3 ndi mapaipi achitsulo opangidwa kuti asamutsire katundu wa axial ndi lateral mu dothi kapena miyala, kupanga maziko odalirika ozama. Milu iyi imapereka kuuma, mphamvu, ndi kugwira ntchito kwanthawi yayitali-pa ntchito zazikulu zapamadzi ndi zapamadzi kuphatikiza milatho, madoko, makoma otsekera, ndi mafakitale.

Ubwino wawo waukulu:

• Kuthamanga kwambiri m'machulukidwe a nthaka
• Kulimba-kwakukulu kwa gawo lopindika
• Kutumiza kwabwinoko konyamula katundu kudzera pakukangana kwapakhungu ndi kubereka komaliza

Chemistry yotsika ya kaboni imathandizira kuwotcherera kwabwino panthawi yolumikizana.

Gulu la 3 limapereka mphamvu zapamwamba kwambiri pansi pa ASTM A252 - zabwino kwambiri-zolemba ntchito zambirimbiri.

Milu ya mapaipi a ASTM A252 Galasi 3 amapangidwa pogwiritsa ntchito njira zingapo zopangira kutengera kukula kwa mulu, zofuna zamapangidwe, ndi mafotokozedwe a polojekiti:

• ERW (Electric Resistance Welded):

Zoyenera kuchulukirachulukira ndi mphamvu zodalirika za msoko komanso mtengo wake-kagwiritsidwe kabwino ka malo{1}}kutengera maziko.

• LSAW (Longitudinal Submerged Arc Welded):

Amapereka kuwongoka kwabwino kwambiri, makoma okhuthala, komanso kukhulupirika kwa weld, yabwino pazomangamanga monga ma pier a mlatho kapena maziko a jekete yakunyanja.

• SSAW / Spiral Welded:

Imayatsa milu yayikulu yokhala ndi kuuma kokongoletsedwa ndi kuthekera kotumiza katundu m'maprojekiti akuzama apanyanja ndi madoko.

Malizitsani Zomangamanga

Kuti agwirizane ndi matope ndi mikhalidwe yoyendetsa, milu imatha kuperekedwa motere:

• Tsegulani-milu yakumapeto

Kulola kulumikiza dothi kapena kuyika kwa socket komwe kumapangitsa kuti kugwedezeka kumathandizira kwambiri

• -zotsekera milu zokhala ndi nsapato zomangika

Kupititsa patsogolo malowedwe a dothi lowundana, kupititsa patsogolo-kubereka bwino, ndi kuchepetsa kuwonongeka kwa mulu poyendetsa galimoto.

Zosankha zopanga izi zimatsimikizira kukhulupirika kwa mulu pansi pazovuta zoyendetsa pomwe zimathandizira kusamutsa katundu moyenera nthawi yonse yautumiki wa muluwo.

Zosankha zazikulu zokhala ndi mainchesi zimapereka kuuma kwapambuyo kwa madoko ndi ma milatho.

Kulunzanitsa minda kudzera m'matako-malo olowa

Kugwirizana kwa weld kumakhudza mwachindunji magwiridwe antchito

Makolala olimbikitsa amkati mwasankha kuti mupitilize kuyendetsa

Kuyesa kwa Ultrasonic kapena radiographic monga momwe zafotokozedwera

Kutengera kuwonongeka kwa malo:

• Malasha-tar epoxy
• Fusion-bond epoxy (FBE)
• Metallized zinc/aluminium spray
• Chitetezo cha Cathodic kwa milu yomira

Izi zimakulitsa moyo wautumiki wa mulu m'madothi am'madzi am'madzi kapena m'mafakitale ankhanza.

Njira zodziwika bwino:

• Impact nyundo kuyendetsa
• Kuyendetsa kwa Hydraulic / vibratory
• Kuthamanga m'mphepete mwa nyanja

Ubwino wamachitidwe:

• Kukhazikitsa mwachangu ndi kukumba kochepa
• Kugwirizana kwamphamvu ndi kudzaza konkriti & makola olimbikitsa
• Thandizo lokhazikika pansi pa mphepo, mafunde, kapena zivomezi

Zabwino kwa:

• Offshore ndi kukwera m'madzi
• Port ndi zida za quay
• Maziko a Bridge
• Zomangamanga zazikulu zamafakitale

Milu yazitsulo ya ASTM A252 Grade 3 imayendetsa bwino kwambiri, imakhala yolimba, komanso imagwira ntchito nthawi yayitali-pamalo omanga m'madzi ndi m'madzi.

Kufufuza kwathunthu, kukonzekera kumapeto, nsapato za mulu, chithandizo cholumikizira, zolemba zonse za MTC, ndi BV / ABS zowonera zomwe zikupezeka - zoperekedwa ndi Octal Pipe.

FAQ

 

 

Q1: Kodi mulu wa chitoliro cha ASTM A252 Grade 3 ndi chiyani?

A1: Kuyika maziko akuya ngati katundu wokhazikika-wonyamula membala kapena ngati chigoba cha konkriti{2}}zodzaza milu.

Q2: Kodi pali kusiyana kotani pakati pa ASTM A252 Grade 2 ndi Grade 3?

A2: Gulu la 3 lili ndi mphamvu zochepa kwambiri (pafupifupi 45 ksi zokolola ndi 66 ksi tensile).

Q3: Kodi ASTM A252 imafuna kuyesa kwa hydrostatic?

A3: Ayi-kuyesa kwa hydrostatic sikunatchulidwe pamilu ya mapaipi ya A252.

Q4: Ndi kulolerana kotani komwe kumayendera milu yamapaipi ya ASTM A252?

A4: Kawirikawiri OD ± 1%, makulidwe a khoma ± 12%, ndi kulemera +15% / -5%.
