Gukoresha ASTM A671/A671MUmuyoboro w'icyuma wa LSAW

Igiciro gito cya ASTM kuri Pipe y'Ibyuma 252

Uburyo bwo gukora

Uburyo bwo gukora umuyoboro wa Longitudinal Submerged-arc Welded (LSAW) Pipe ni ubu bukurikira:

Gupima icyuma gipima icyuma gipima → gusya impande → gucuranura mbere → gushushanya → Gusudira mbere → Gusudira imbere → Gusudira hanze → Gusuzuma icyuma gipima → Gusuzuma X-ray → Kwagura → ikizamini cya hydraulic → l. Gusukura → Gusuzuma icyuma gipima → Gusuzuma X-ray → Gusuzuma X-ray → Gusuzuma uduce twa magnetic ku mpera y'umuyoboro

Ibisobanuro birambuye by'umuyoboro w'icyuma cya karuboni wa ASTM A671 LSAW(JCOE):

Ikorwa: Imiyoboro y'icyuma ya LSAW (JCOE)

Ingano: OD: 406~1500mm Uburemere: 6~40mm

Icyiciro: CB60, CB65, CC60, CC65, n'ibindi.

Uburebure: 12M cyangwa uburebure bwagenwe uko bikenewe.

Impera: Impera isanzwe, Impera ifite imigozi, Ifite imigozi;

2. Itandukaniro riri hagati y'umurambararo munini n'umurambararo muto wo hanze.

3. Guhuza-Gukoresha uburebure bwa metero 3 bushyizwe ku buryo impera zombi zihura n'umuyoboro, 1/8 santimetero (3mm).

4. Ubunini - Ubunini bw'urukuta ntarengwa ahantu hose mu muyoboro ntibugomba kurenza santimetero 0.01 (0.3mm) munsi y'ubunini bwagenwe.

5. Uburebure bufite impera zidakozwe mu mashini bugomba kuba hagati ya -0 + 1/2 santimetero (-0 + 13 mm) y’ibyavuzwe. Uburebure bufite impera zikozwe mu mashini bugomba kuba nk’uko byemejwe hagati y’uwakoze n’uwaguze.

Ibizamini bya tekiniki ku muyoboro wa ASTM A671 LSAW Carbon Steel:

Isuzuma ry'Umuvuduko—Imiterere yo gukurura inyunganiramikorere y'urusobe rw'imigozi igomba kuba yujuje ibisabwa kugira ngo ibikoresho bya plate bikomere cyane.

Ibizamini byo gucukura biyobowe na transverse-guided-weld-bend —Ikizamini cyo gucukura kigomba kwemerwa niba nta mvune cyangwa izindi nenge zirenze 1/8 santimetero (3mm) mu cyerekezo icyo ari cyo cyose zigaragara mu cyuma cyo gucukura cyangwa hagati y’icyuma cyo gucukura n’icyuma cyo hasi nyuma yo gucukura.

Isuzuma rya radiyo-shusho-Uburebure bwose bwa buri shuli yo mu cyiciro cya X1 na X2 bugomba gusuzumwa hifashishijwe radiyo hakurikijwe kandi bukujuje ibisabwa n'amategeko agenga ASME Boiler and Pressure Vessel Code, Ingingo ya karindwi, igika cya UW-51.
