ASTM A335 P22 yeeb nkabyog seamless chromium-molybdenum alloy steel yeeb nkab nrog cov tshuaj muaj pes tsawg leeg uas muaj 1.90% mus rau 2.60% chromium thiab 0.87% mus rau 1.13% molybdenum. P22 seamless kav ua tau zoo nyob rau hauv siab -kub oxidation tsis kam, nrog rau tensile lub zog, yield zog, thiab toughness. ASME SA335 P22 yog cov khoom siv zoo tshaj plaws rau kev siv cov boilers, tshav kub exchangers, superheater raj, thiab chav piping systems ua hauj lwm ntawm kub tshaj 540 degree. HT PIPE muab Alloy P22 yeeb nkab nrog cov kev pabcuam customization.
ASME SA335 P22 Khoom Khoom:
- Kev pab kub ntau: -29 ℃ to 650 degree
- Zoo heev -kub creep zog
- Oxidation kuj
- Resistance rau hydrogen sulfide corrosion
- Zoo weldability; yuav tsum tau preheating thiab Post-Weld Heat Treatment (PWHT)

Cov neeg muab khoom ASME SA335 P22 Fabrication
ASTM A335 cov khoom yuav tsum yog seamless yeeb nkab (kub- dov / txias- kos); welded yeeb nkab yog nruj me ntsis txwv tsis pub.
Kev kho cua sov:
- Normalizing (kwv yees . 900-940 degree) + Tempering (kwv yees . 730-790 degree);
- Tag nrho annealing kuj tso cai;
- Ncej -Weld Heat Treatment (PWHT) yog qhov yuav tsum tau ua tom qab vuam.
Vuam Electrode Rau P22 Khoom
- Kev Npaj Cov Yeeb Nkab → Yeeb Nkab Preheating → Xaiv Txoj Kev Vuam → Xaiv Cov Khoom Siv Filler → Root Pass → Sau thiab Cap Passes → Ncej - Weld Thaum tshav kub kub kho (PWHT) → Kev tshuaj xyuas
- P22 yeeb nkab tuaj yeem welded siv GTAW, fusion vuam, ER80S-B2
