Uglerod po'lat payvandlash quvurining asosiy ishlab chiqaruvchilari dunyoda nima?
Xitoy dunyodagi eng katta payvandlangan quvur prodyuseri (ishlab chiqarishning 55% dan ko'prog'ini hisobga olgan holda), asosiy kompaniyalar bastel, Tianjin Siz} Yaponiya (JFE, Sumitomo) - uning kuchli va korroziyasiz payvandlangan payvand qilingan quvurlar bilan mashhur; Germaniya (Salzgitter) aniq payvandlangan quvurlarga qaratilgan; AQSh (AQSh po'lat) 2023 yilda . API quvurlariga qaratilayotgan API quvurlariga ko'ra, 50 million tonna (asosan janubi Osiyo va Yaqin Sharq) infratuzilmasiga bo'lgan talabi o'sib bormoqda . Tirik ishqalanish Evropa va Amerika Qo'shma Shtatlariga Xitoy payvandlash uchun 15% -25 .
Yangi energiya sanoatining payvandlash quvurlariga qanday ta'siri qanday?
Fotoalbolli payvandlangan quvurlar uchun talab (7} 2 mmm) the Wind Power Power Power Savative ({6} 0} tonnadan iborat PhyShore katta diametrli (ph2000mm yoki undan ko'p) qalin devordan foydalanadi (30-60mm) welded pipes, and the material is upgraded to S355ML. Hydrogen energy pipelines promote the development of X80 grade welded pipes (anti-hydrogen embrittlement treatment). Nickel-plated steel strip welded pipes (thickness 0.5mm±0.02mm) Lityum batareya chig'anoqlari juda aniq talablarga ega. Yangi energiya transport vositalarining zaryadlash zaryadlash uchun qavslar kvadrat naychalarga bo'lgan talabni (100 × 100 × 200 mm) bajaradi va global yangi energiya payvandlash quvurlari 8 million tonnadan oshishi kutilmoqda 2025.}} {{}}
Payvandlash quvur ishlab chiqarish jarayonlari uchun yashil ishlab chiqarishning talablari qanday?
Evropa Ittifoqi Uglerod chegarasi solig'i (CBAM) kompaniyalari tonna bir tonna (maqsad<1.2 tons). Measures include: ① ERW welded pipes are switched to photovoltaic power (40% emission reduction); ② Short-process smelting of scrap steel (60% carbon reduction compared to blast furnace process); ③ Pickling-free technology (laser cleaning instead of hydrochloric acid); ④ Water-based paint instead of solvent-based. Baosteel's "green welded pipe" has passed EPD certification, and the life cycle assessment (LCA) shows a carbon footprint of 1.8kgCO₂/kg pipe. In the future, hydrogen ironmaking technology may completely change the production method of welded pipe raw materials.
Yuqori kuchliroq va engil payvandlangan quvurlarning rivojlanish tendentsiyasi qanday?

Aerosokome maydonida {{12} Payvandlash lazer-yassi gibrid payvandlashini talab qiladi (15kj / sm dan past) ni yumshatishni oldini olish uchun.
Kelajakda payvandlangan quvurlar sanoatining raqobatbardosh landshaft qanday o'zgaradi?
Raqamli konstruktsiya kalitga aylanadi: Smart fabrikalari AI Sifatli quvurlarni amalga oshiradi. Tezlatilgan: ARCECORMITTAL Hindistonning Esarli payvandlangan quvur zavodini .} 5% ni tashkil qiladi, shunda 2030 yilda, ular 350 milliard AQSh dollarini tashkil etadi, shundan iboratki, chuqurlik quvurlari va vodorod quvurlari 35 foizni tashkil etadi.
