ASTM A252 Icyiciro cya 3 Umuyoboro PileASTM A252 Icyiciro cya 3 Umuyoboro

ASTM A252 Ikirundo cyicyiciro cya 3 nicyuma cyubatswe cyicyuma cyagenewe kwimura imitwaro ya axial na kuruhande mubutaka cyangwa urutare, bikora sisitemu yizewe yimbitse. Ibi birundo bitanga ubukana, ubushobozi, hamwe nigihe kirekire - imikorere yigihe kinini kubikorwa bya gisivili n’inyanja birimo ibiraro, ibyambu, inkuta zigumana, hamwe n’inganda.

Ibyiza byabo nyamukuru:

• Kugenda cyane mubibazo byubutaka
• Kinini - igice gikomeye cyo kunama
• Kwimura ibintu byiza cyane ukoresheje uruhu rwo guterana no kurangiza

Ubuhanga bwa karuboni nkeya bushigikira gusudira neza mugihe cyo gutera.

Icyiciro cya 3 gitanga imbaraga zisumba izindi munsi ya ASTM A 252 - nziza kuburemere -.

ASTM A252 Ikirundo cyicyiciro cya 3 cyakozwe hifashishijwe inzira nyinshi zibyara umusaruro ukurikije ingano yikirundo, ibisabwa byubatswe, hamwe nibisobanuro byumushinga:

• ERW (Imashanyarazi irwanya amashanyarazi):

Bikwiranye nuburinganire busanzwe hamwe nimbaraga zizewe hamwe nigiciro - gutanga neza kubutaka - imirimo ishingiro.

• LSAW (Longitudinal Submerged Arc Welded):

Itanga ubugororangingo buhebuje, inkuta zibyimbye, hamwe nuburinganire bwo hejuru bwo gusudira, nibyiza kubikorwa bikomeye nkibiraro byikiraro cyangwa umusingi wikoti rya offshore.

• SSAW / Spiral Weld:

Gushoboza ibirundo binini bya diameter hamwe no gukomera hamwe nubushobozi bwo kohereza imitwaro mumishinga yimbitse yo mu nyanja no ku cyambu.

Kurangiza Amahitamo yo Kubaka

Guhuza imyanda itandukanye nuburyo bwo gutwara, ibirundo birashobora gutangwa nka:

• Fungura - ibirundo byanyuma

Kwemerera gucomeka ubutaka cyangwa gushiraho urutare aho kurwanya ubukana bigira uruhare runini mubushobozi

• Gufunga - ibirundo byanyuma hamwe ninkweto yo gusudira

Gutezimbere kwinjira mubutaka bwuzuye, kunoza impera - kwihanganira imikorere, no kugabanya ibyangiritse mugihe cyo gutwara

Izi nzira zo gukora zituma ubudakemwa bwikirundo mugihe uhangayikishijwe no gutwara ibinyabiziga mugihe cyohereza imitwaro neza mubuzima bwa serivisi.

Amahitamo manini ya diametre atanga ubwiyongere bukomeye kuruhande rwibyambu nibiraro.

Gutera umurima ukoresheje buto - gusudira hamwe

Guhuza gusudira bigira ingaruka kumikorere

Imbere yo gushimangira imbere yimbere kubushake bwo gukomeza

Ikizamini cya Ultrasonic cyangwa radiografiya nkuko byasobanuwe

Ukurikije ikibanza cyangirika:

• Amakara - epoxy
• Guhuza - bihujwe na epoxy (FBE)
• Zinc / aluminium spray
• Kurinda Cathodic kubirundo byamazi

Izi ngamba zongerera serivisi ibirundo mubutaka bwo mu nyanja cyangwa ubukana.

Uburyo busanzwe:

• Ingaruka zo gutwara inyundo
• Gutwara Hydraulic / vibratory
• Kujya mu nyanja y'umusenyi

Inyungu zo gukora:

• Kwishyiriraho byihuse hamwe nubucukuzi buke
• Guhuza gukomeye hamwe na beto yuzuye & kongeramo imbaraga
• Inkunga ihamye munsi yumuyaga, umuraba, cyangwa umutwaro wikurikiranya

Icyifuzo cya:

• Kuruhande rwinyanja hamwe ninyanja
• Urukuta rw'icyambu
• Urufatiro rw'ikiraro
• Inzego nini zinganda

ASTM A252 Icyiciro cya 3 cyicyuma cyicyuma gitanga uburyo bwiza bwo gutwara, kuramba kumiterere, hamwe nigihe kirekire - mikorere yigihe kirekire mugusaba ubwubatsi bwabaturage ninyanja.

Gukurikirana byuzuye, gutegura kurangiza, inkweto zirunda, gutera inkunga, ibyangombwa bya MTC byuzuye, hamwe na BV / ABS biboneye ubugenzuzi buboneka - butangwa na Octal Pipe.

Ibibazo

 

 

Q1: ASTM A252 Icyiciro cya 3 cyicyuma gikoreshwa ni iki?

A1: Urufatiro rwimbitse nkumutwaro uhoraho - utwara umunyamuryango cyangwa nkigikonoshwa cya beto - yuzuye ibirundo.

Q2: Ni irihe tandukaniro riri hagati ya ASTM A252 Icyiciro cya 2 nicyiciro cya 3?

A2: Icyiciro cya 3 gifite imbaraga ntarengwa (hafi 45 ksi umusaruro na 66 ksi tensile).

Q3: ASTM A252 ikenera ikizamini cya hydrostatike?

A3: Oya - kwipimisha hydrostatike ntabwo bisobanuwe kubirundo bya A252.

Q4: Ni ubuhe bworoherane bukoreshwa kuri ASTM A252 ibirundo?

A4: Mubisanzwe OD ± 1%, uburebure bwurukuta ± 12%, nuburemere +15% / −5%.
