[Dongmeng Steel] - Sizning ishonchli ishlab chiqaruvchi va yetkazib beruvchingizASTM A312 zanglamaydigan po'lat quvurlar, ASTM A312 zanglamaydigan po'lat quvur 4 ta asosiy sinfga egaTP304/304L, TP316/316L. sanoat toifasidagi quvurli yechimlar uchun oʻlchamlar va texnik xususiyatlarning toʻliq diapazoni- taklif etadi. Biz ixtisoslashganmizASTM A312 choksiz va payvandlangan quvurlar, turli xil tashqi diametrlarni va devor qalinligini, jumladan, umumiy bosim darajalarini qoplaydiJadval 10Sva40-jadval. Neft va gaz, kimyoviy qayta ishlash, dengiz muhandisligi va oqava suvlarni tozalash kabi ko'plab B2B tarmoqlari ehtiyojlarini qondirish uchun maxsus o'lchamlar ham mavjud.
BizningASME A312 zanglamaydigan po'lat quvurlara'lo darajada past-haroratga chidamliligini ta'minlang va o'ta sovuq muhitda ham yuqori- ishlashni saqlang. Yuqori xlorid korroziyaga chidamliligi bilan ular chuqurchalar va yoriqlar korroziyasiga sezilarli darajada qarshilik ko'rsatadi, bu ularni kema qurish, dengiz suvini tozalash tizimlari va dengiz platformalari uchun quvurlar tizimlari kabi yuqori-xloridli ilovalar uchun ideal qiladi.

1. ASTM A312 zanglamaydigan po'lat quvur nima?
ASTM A312 - bu ASTM International tomonidan chiqarilgan standart spetsifikatsiyachoksiz, payvandlangan va qattiq sovuq ishlangan-ostenitik zanglamaydigan po‘lat quvurlaryuqori harorat va umumiy korroziv-xizmat uchun moʻljallangan.
2. ASTM A312 bo'yicha qanday sinflar qamrab olingan?
Umumiy baholarga quyidagilar kiradi:
TP304 / TP304L
TP316 / TP316L
TP321
TP347
TP310S
Ular orasida TP316L yuqori korroziyaga chidamliligi tufayli kimyoviy va dengiz muhitida keng qo'llaniladi.
3. ASTM A312 TP304 va TP316 o'rtasidagi farq nima?
Asosiy farq shundakimolibden (Mo) tarkibi:
TP304- Umumiy korroziyaga qarshilik
TP316– 2–3% Mo ni o‘z ichiga oladi, bu xloridlarga va chuqur korroziyaga yaxshi qarshilik ko‘rsatadi
