ASTM A335 P11 High-Pressure Seamless Tube
ASTM A335 yog tus qauv rau qhov kub thiab txias siab seamless alloy steel yeeb nkab siv hauv cov chaw tsim hluav taws xob thiab lwm yam kev lag luam. Cov kav dej no yog ua los ntawm chrome molybdenum steel thiab yog tsim los tiv taus qhov kub thiab txias. ASTM A335 P11 seamless tubing yog tsim los ntawm chrome-molybdenum alloy steel nrog tsawg kawg nkaus chromium ntsiab lus ntawm 1 feem pua thiab 0.25 feem pua molybdenum. Carbon, silicon, manganese, phosphorus, sulfur, thiab nitrogen kuj muaj nyob rau hauv cov hlau. Alloying ntsiab txhim kho lub zog, toughness, thiab corrosion kuj ntawm cov kav dej.
ASTM A335 P11 seamless tubing muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab tuab kom haum rau ntau yam kev siv. Tubing muaj nyob rau hauv ODs xws li 1/8 "mus rau 24" thiab phab ntsa thickness xws li SCH 20 txog SCH XXS. Tube ntev tuaj yeem nyob ntawm ib qho ntev (SRL) mus rau ob lub sijhawm ntev (DRL) lossis raug kho kom tau raws li qhov xav tau ntawm cov neeg siv khoom.

Qhov siab tshaj plaws kub txwv ntawm ASTM A335 P11 alloy steel yeeb nkab yog 600 degree (1112 degree F), thiab nws yog siv nyob rau hauv high-pressure daim ntaub ntawv xws li chav boilers, pipelines, thiab siab hlab ntsha. Ib txoj kev kub los yog txias-daws yog siv los ua cov raj seamless, uas ua kom cov phab ntsa tuab tuab thiab zoo kawg nkaus polish. ASTM A335 P11 seamless tubing muaj lub zog tensile siab, zoo ductility, thiab zoo heev corrosion thiab oxidation kuj, ua rau nws zoo tagnrho rau high-pressure thiab high-temperature daim ntaub ntawv uas yuav tsum tau kev cia siab thiab durability.
ASTM A335 P11 seamless tubing yog siv nyob rau hauv ntau lub lag luam, xws li lub zog tsim, roj thiab roj, petrochemicals, thiab refineries. Lawv feem ntau yog ua haujlwm nyob rau hauv high-temperature, high-pressure applications, nrog rau chav boilers, tshav kub exchangers, pipelines, thiab siab hlab ntsha. Cov kav dej no kuj tau siv rau hauv kev tsim kho ntawm superheater thiab reheater raj hauv thermal fais fab nroj tsuag, uas pab txhawb rau cov nroj tsuag kev ua tau zoo thiab kev vam khom.
Cov yam ntxwv ntawm ASTM A335 P11 High-Pressure Seamless Tube
- Zoo heev mechanical zog
- Zoo heev corrosion thiab oxidation tsis kam
- Kev ua tau zoo ntawm qhov kub thiab txias
- Zoo heev durability
- Zoo heev nto finish
- Zoo ductility thiab toughness
ASTM A335 P11 Seamless Yeeb Nkab yog raug rau ntau qhov kev ntsuam xyuas kom paub tseeb tias nws qhov zoo thiab kev cia siab. Kev tshuaj ntsuam xyuas tshuaj, kev ntsuas lub zog tensile, kuaj hardness, kuaj qhov cuam tshuam, thiab ntsuas hydrostatic yog cov kev xeem ua. Cov kev sim uas tsis yog kev puas tsuaj xws li kev kuaj ultrasonic, kev ntsuas tam sim no, thiab kev kuaj cov hlau nplaum kuj tuaj yeem siv los nrhiav qhov tsis zoo lossis tsis zoo.
