Shiinaha oo tayo sare leh ASME/API/GOST/DIN/En/JIS Dhuumaha birta ah ee aan xidhnayn iyo alxanka
Dulmar
Waxa kaliya ee aan sameyno waxaa badanaa lala xiriiriyaa mabda'aheena " Shopper marka hore, ku kalsoonow aad marka hore, u go'doominta baakadaha cuntada iyo badbaadada deegaanka ee tayada sare leh ee aan xudduudaha lahayn iyo birta alxanka leh, waxaanu dhignaa sax iyo caafimaadka mas'uuliyadda koowaad. Hadda waxaan leenahay xirfadle Shaqaale ganacsi oo caalami ah oo ka soo qalin jabiyay Ameerika waxaanu ahayn lammaanahaaga ganacsi ee soo socda. Asal ahaan, shirkadeena waxay sii wadaysaa hal-abuurnimada, oo ay ka go'an tahay inay ku siiso alaabada ugu qaalisan iyo adeegga iibka ka dib.
Ka mid ah qalabka caadiga ah ee qaab dhismeedka birta birta ah, DIN1629 ST52 waa mid ka mid ah alaabta inta badan la isticmaalo. Heerarka Shiinaha, badanaa waxay u dhigantaa GB/T8162 Q345B. Labada waa la isku bedeli karaa midba midka kale, laakiin si buuxda iskuma dhigna. .
Marka la eego isku dhafka kiimikada:
DIN 1629 ST52: C: 0.17% max; P: 0.04% ugu badnaan; S:: 0.04% ugu badnaan; N: 0.009% ugu badnaan
GB/T 8162 Q345B: C: 0.2% ugu badnaan; P: 0.035% ugu badnaan; S:: 0.035% ugu badnaan; N: 0.012% ugu badnaan
Waxaa la arki karaa in labada halbeeg ay si wadajir ah u qeexayaan in waxa ku jira walxaha kiimikaad ay asal ahaan isku mid yihiin.
Waxqabadka makaanikada:
DIN 1629 ST52: Xoog xajin: 500 ~ 650Mpa; Awoodda wax-soo-saarka: 335 ~ 355Mpa; Ballaarinta (dhererka): 21% min
GB/T 8162 Q345B: Xoog xajin: 470 ~ 630Mpa; Awoodda wax-soo-saarka: 295 ~ 345Mpa; Ballaarinta (dhererka): 20% min
Shuruudaha qalabka farsamada ee labada ayaa sidoo kale qiyaas ahaan isku mid ah
Tijaabi walxaha:
DIN 1629 waxay u baahan tahay tijaabinta xajinta, tijaabada fidsan, tijaabada cidhiidhiga, kormeerka dusha sare, kormeerka cabbirka; falanqaynta alaabta dhammaatay
GB/T8162 Q345B waxay u baahan tahay kormeerida ka kooban kiimikaad, Tijaabada adkaysiga, tijaabada adkaanta, tijaabada saamaynta 20℃, tijaabada fidsan, tijaabada foorarsiga, tijaabada korantada ee aan burburin
Waxaa la arki karaa in shuruudaha mashruuca tijaabada ah ee GB/T8162 Q345B asal ahaan ay daboolaan DIN1629
Shuruudaha dulqaadka:
DIN1629 wuxuu dhigayaa:
Dulqaadka OD:
OD≤100mm, ±1% ama ± 0.5mm
100mm OD≤200mm, ± 1%
OD >200mm, ± 1%
Dulqaadka WT:
OD≤130mm: ≤2* heerka WT: + 15% -10%
2*Standard WT<s≤4* heerka WT:+12.5% -10%
>4* Heerka WT: ± 9%

0.11 * heerka WT: ± 10%
320mm<OD≤660mm:≤0.05* Heerka WT: + 20% -15%
0.05*Standard WT<s≤0.09* heerka WT: +15% -12.5%
0.09* heerka WT: + 12.5% -10%
GB/T8162 ayaa dhigaya:
Dulqaadka OD:
± 1% ama ± 0.5mm ee ka weyn
Dulqaadka WT:
OD≤102mm: ± 12.5% ama ± 0.4mm ee ka weyn
OD >102mm: WT≤0.05mm, ± 15% ama ± 0.4mm kuwa weyn
0.05mm<WT≤0.1mm, ± 12.5% ama ± 0.4mm kuwa weyn
WT :0.1mm, +12.5% -10%
Dulqaadka labada ayaa sidoo kale qiyaas ahaan isku mid ah
Sidaa darteed, Q345B iyo ST52 waa la isku bedeli karaa midba midka kale marka loo isticmaalo jawi caadi ah mana jirto shuruud gaar ah. Marka deegaanka ama shuruudaha ay aad u adag yihiin, isbarbardhigga wuxuu u baahan yahay in si taxadar leh loo tixgeliyo.
