Mahsulot tavsifi

 Neft qudug'i Rojdestvo daraxti klapan korpusi - bu quduqdan uglevodorodlar oqimini boshqarish uchun neft va gaz quduqlari tizimlarida ishlatiladigan bosim o'z ichiga olgan komponent. Valflar, g'altaklar va armaturalarning daraxtga o'xshash konfiguratsiyasi uchun nom olgan Rojdestvo daraxti haddan tashqari bosimlarda (10 000 PSI gacha), korroziy H2S / CO2 muhitida va keng harorat oralig'ida (-50 ° C dan + 120 ° C gacha) ishlaydi. 
 Ningbo Ruican ushbu valf korpusini AISI 4130 past qotishma po'latdan nozik investitsiya quyish yordamida ishlab chiqaradi, so'ngra gardish yuzlari, tishli ulanishlar va ichki oqim o'tish joylarini ko'p eksa CNC ishlov berish. Barcha komponentlar API 6A spetsifikatsiyasi va NACE MR0175 sulfidli stress yorilishiga qarshilik talablariga muvofiq ishlab chiqariladi.
