Peb peb lub ASTM A105 Carbon Steel Threaded Flanges ua kom daws tau cov teeb meem hauv cov kav dej uas tsis muaj hluav taws kub (welding) uas tsis yooj yim. Cov xov uas muaj (ASME B1.20.1 compliant) nkag siab tob rau hauv cov kav dej yam tsis muaj stripping – peb muaj cov ntawv qhia uas qhia tau tias muaj 30% ntau dua pull-out strength dua li machined-thread competitors.
Nrog 485-655 MPa tensile strength (per ASTM A105), lawv tuav tau Class 150-300 systems mus txog 360°F (182°C) yam tsis muaj teeb meem. Qhov tseem ceeb yog peb cov carbon uas tswj tau (0.25-0.29%): muaj zog txaus rau cov steam lines, tab sis tseem muaj peev xwm weld tau thaum koj xav hloov kho. Piv nrog stainless, koj yuav tau txais 40-65% ntau dua rau ib lub unit ntawm cov non-corrosive applications xws li compressed air lossis hot oil circuits.
Txhua lub Carbon Steel Threaded Flange tau txais peb qhov kev kho tshwj xeeb:
Lub flange no yog hot-forged los ntawm vacuum-degassed steel. Nrog cov impurities tsawg dua hauv cov steel, muaj cov defects tsawg dua ntawm cov xov.
Ua ntej threading, tau ua stress relief treatment ntawm 1200 degrees Fahrenheit (txog 650 degrees Celsius) kom cov xov tsis yooj yim deformed tom qab ua tiav.
CNC-cut threads nrog Class 2B fit (nruj dua li ASME's 3B requirement)
Zinc-plated per ASTM B633 Type II (48-hour salt spray tested)
Peb tshuaj xyuas cov xov peb zaug nrog go/no-go gauges thiab 3D scanners – vim tias cov fittings uas tsis zoo yuav ua rau koj poob cov neeg yuav khoom.
Tab tom ua haujlwm nrog 4 kab tshwj xeeb nrog:
20000-piece lub peev xwm txhua hli (npaj txhij rau cov refinery turnarounds)
150+ thread rolling dies (1/8" rau 12" NPT tag nrho)
Real-time PMI checks (handheld XRF txheeb xyuas chemistry ntawm qhov chaw)
Barcode-tracked MTCs nrog heat numbers (tsis muaj paperwork yuam kev)

Cov Lus Qhia Tseem Ceeb (Key Selection Tips)
Plumbing & Domestic Water
Q235B, ASTM A105
Tap water, cold water
Ua ntej xam nqi; Class 150 txaus rau low pressure.
Oil & Gas (Low-Pressure Lines)
ASTM A105, A350 LF2
Natural gas, light oil (≤300 psi)
Xaiv LF2 rau cold climates; xyuas kom thread sealant compatibility.
Chemical Processing (Mild)
Neutral solvents, coolants
Tsis txhob siv kub siab (>400°C); siv Teflon tape rau sealing.
Fire Protection Systems
Water, fire-retardant fluids
Class 150 zoo tshaj rau kev nruab sai (tsis tas yuav weld).
HVAC Piping
Q235B, ASTM A36
Refrigerants, hot water (≤100°C)
Xaiv BSPP
Tsis Tas Yuav Weld (No Welding Needed)
