Njira Yopangira ASTM A53Mtengo wa ERW:

By kukana magetsi welded

Kuyendera kwa chipani chachitatu

Kuyesa kwamphamvu kwa thupi la chitoliro-Kuyesa kwamphamvu kuyenera kuchitidwa molingana ndi ISO6892 kapena ASTM A370.Zitsanzo za nthawi yayitali ziyenera kugwiritsidwa ntchito.Kawiri pagawo lililonse loyeserera la chitoliro chokhala ndi chiŵerengero chofanana cha kuzizira kwa abd

Mayeso a Flattening-Kuyesa kuphatikizika kumodzi kudzapangidwa pazitsanzo kuchokera kumapeto kwa machubu awiri osankhidwa pagawo lililonse.

Kupinda Mayeso- utali wokwanira wa chitoliro uyenera kuyima kukhala wopindika kupyola 90 ° kuzungulira cylindrical mandrel.

Mayeso osawononga magetsi-monga m'malo mwa kuyesa kwa hydro-static, thupi lonse la chitoliro chilichonse lidzayesedwa ndi mayeso osawononga magetsi.Kumene kuyesedwa kosawonongeka kwa magetsi kumachitidwa, kutalika kwake kumalembedwa ndi zilembo"NDE"

Kuyesedwa kwa Hydrostatic-Chubu chilichonse chidzayesedwa ndi hydro-static pressure test.

100% mayeso a X-ray a seam weld.

Kuyeza kwa ultrasonic.

Kufufuza kwamakono kwa eddy.

Kugwiritsa ntchito kwaChitoliro chachitsulo cha ASTM A53 ERW:

Chitoliro chachitsulo cha ERW mu mulingo uwu ndi Wamakina ndi kukakamiza ndipo ndi chovomerezeka kugwiritsidwa ntchito wamba mu nthunzi, madzi, gasi, ndi mizere ya mpweya.Ndi oyenera kuwotcherera, ndi oyenera kupanga maopareshoni okhudza coiling, kupinda, ndi flanging.

Katundu Wamakina:

TensileZofunikira:

	Gulu A	Gulu B
Mphamvu yamphamvu, min, psi (MPa)	48000 (330)	60000 (415)
Mphamvu zokolola, min, psi (MPa)	30000 (205)	35000 (240)

Kupakira kwaMtengo wa ERW:

Chitoliro chopanda kanthu, zokutira zakuda / Varnish, zokutira zinki ndi zokutira epoxy, ndi zina (zosinthidwa);
6 ndi pansi m’mitolo ndi gulayeti ziwiri za thonje;
Zonsezi zimathera ndi otetezera mapeto;
Mapeto osavuta, malekezero a bevel (2"ndi pamwamba ndi ma bevel malekezero, digiri: 30 ~ 35 °), ulusi ndi kulumikizana;
Kuyika chizindikiro.
