QAUV Pawg ntawm ASTM cov qauv cuam tshuam rau hluav taws xob tiv thaiv welded hlau kav

ASTM cov qauv npog muaj cov ntsiab lus ntau, tab sis peb pawg yog qhov tseem ceeb tshaj plaws rau HUAYGANThluav taws xob tiv thaiv welded steel yeeb nkabKev Lag Luam: Cov Qauv Qauv (Kev txhais cov qauv hlau), cov qauv khoom lag luam (tswj cov yeeb nkab tshwj xeeb), thiab cov qauv ntsuas (tawm cov txheej txheem pov thawj).

Cov Qauv Cov Qauv: Txhais cov qauv hlau qib hlau

Cov qauv khoom siv qhia txog cov tshuaj lom neeg muaj kuab lom thiab cov khoom siv zoo ntawm cov hlau siv los uaCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, ua kom tau cov khoom siv raw.

ASTM A36: Tus ua haujlwm rau ERW kav

ASTM A36 yog qhov ntau siv cov roj carbon qauv txheem steel txheem, zoo tagnrho rau tib yamHlobCov kav dej hauv qis - rau -} nruab nrab siab siab kawg siab:

Tshuaj Muaj Tshuaj: C Tsawg dua los yog sib npaug rau 0.29%, mn 0.80%- 1.050, p tsawg dua lossis sib npaug lossis sib npaug los yog sib npaug zoo weldability thiab lub zog nruab nrab. Huayang Qhov chaw A36 Hlau Coils los ntawm cov ntawv pov thawj (piv txwv li, Baosteel, Shougang, Shougang) thiab ua Spectrometric Testing kom paub tseeb muaj pes tsawg leeg; Hauv 2024, 3 pob khoom ntawm cov coils nrog ntau cov pa roj carbon ntau (0.31%) tau raug tsis lees paub kom tsis txhob Weld Brittleness;

Cov Khoom Siv Neeg Kho Tshuab: Tensile lub zog 400mpa {{4 4}} 550mpa, elongation ntau dua los yog sib npaug rau cov kab lis dej num ib tug kab mob scaffolding thiab cov kab sib sau ua ke. Huaayang Ely48 × 3.5mmHlobCov kav dej (A36) muaj lub zog nruab nrab ntawm 460Mpa, tshaj tus qauv tsawg kawg thiab txhawb nqa 200kg / m load) Guangzhou CBD Skyscraper Project.

ASTM A106 Qib B: High {{}}}} Kev Ua Yeeb Nkab Hlau rau HFW Kav

ASTM A106 qib B yog cov qauv roj carbon steel rau siab-}}} qhov siab kav, ua haujlwm raws li Huayang'sHFW Steel Kav:

Tshuaj Muaj Tshuaj: C Tsawg dua lossis sib npaug 0.30%, mn 0.29%-}} Huayang tswj hwm qis dua lossis sib npaug rau 0.030% rau A106 qib BHFW Steel Kav, txo qis kub tawg kev phom sij los ntawm 40% vs. A36;

Cov Khoom Siv Neeg Kho Tshuab: Tensile lub zog 415Mpa {{4 4}} 550mpa, tawm los ntawm 241mpa, elongation ntau dua los yog sib npaug rau 22% -thes cov khoom sivHFW Steel KavTxhawm rau tiv taus 6MPA siab hauv cov roj sib kis. Lub 2023 shanxi - BeiJing Nkev Pipeline Siv HUAYAG LUB A106 Qib BHFW Steel Kav(Φ219 × 8mm), uas walstood 8Mpa hydrostatic kev sim yam tsis muaj kev xau.

Cov Qauv Khoom: Kev Tswj Xyuas Hluav Taws Xob Hluav Taws Xob Ntau Welded Steel Yeeb Nkab

Cov qauv khoom txhais cov qauv seem, cov qauv, thiab kev ua tau zoo rauCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, kom ntseeg tau lawv cov kev xav tau thov.

ASTM A53: Txheem rau ERW kav hauv qis -- cov ntawv thov nruab nrab

ASTM A53 yog thawj tus qauv rau seamless thiab welded steel kav, suav nrogHlobCov kav dej, npog ob qib (A thiab B) rau dej, roj av, thiab chav dej sib kis:

Kev yuav tsum tau muaj tsawg yam nyob sab: Rau kev teem sijhawm 40HlobCov kav dej (piv txwv li, φ100 φ100 φ 0 6. 6.TTM A53 qhia txog cov txheej txheem tuab 0.79 hli thiab phab ntsa thickness kam rau ± 12.5%. Huaayang ntau tshaj cov qauv no, kev ua tiav ± 0.1mm od thev tau ntawm laser sizing, kom pom kev sib xyaw ua ke nrog lub qhov muag weld fittings;

Weld zoo: ASTM A53 xav tauHlobCov kav dej kom dhau hydrostatic kuaj (1.5 × rated siab) thiab tsis yog- kev sim weld. Huaayang Ua 100% HydOSTATIC TESTING (1.8MPA rau φ100mm kav) thiab 100% ultrasonic khuam kom nrhiav tau (ut) rau A53Hlobkav dej, nrog 99.7% dhau tus nqi hauv 2024;

Daim Ntawv Thov Thov: 2024 baoding them taus tsev num siv 3,000 tons ntawm Huayang lub TTM A53 qib BHlobCov kav dej (М5 × 2.77mm) rau dej muab {} Lawv ua raws li cov nqi qis (tsawg dua lossis muaj kev sib npaug ntawm lub neej.

ASTM A106: Txheem rau HFW kav hauv siab -} siab scarsios

ASTM A106 Siv rau cov roj hlau steel rau siab- kev pabcuam kub (txog li 454 degree), ua rau nws tseem ceeb rau HUAYGANHFW Steel KavHauv lub hwj chim tiam thiab roj refining:

Siab - kub kev ua tau zoo: ASTM A106 qib b yuav tsum tau cov kav dej kom muaj zog kom lub zog loj dua los yog sib npaug ntawm 400℃{3} huayang'sHFW Steel KavNtsib qhov no ntawm Post - weld annealing (720℃-750 degree), ua kom muaj kev deformation hauv thermal cog cov kab;

NDT yuav tsum tau: ASTM A106 MOMILATE X - Cov Hluav Taws Xob Hluav Taws Xob rau 10% ntawm cov kav dej (20% rau cov phiaj xwm sab hauv weld. Lub 2024 Tangshan Thermal fais fab nroj tsuag yuav tsum tau 20% x {{{} Ray Kev kuaj xyuas ntawm Huayang's φ273 × 10mmHFW Steel Kav-} txhua tus dhau nrog cov khoom tsis xws luag;

Daim Ntawv Thov Thov: Ib 2023 Indonesian Roj Refinery siv 2,000 tons ntawm Huayang's A106 qib BHFW Steel Kav(Φ219×8mm) for 6MPa crude oil transmission-ASTM A106 compliance enabled the pipes to withstand corrosive oil and high pressure without failure.
