Shanghai Toko Tech Co, Ltd. is a professional manufacturer and supplier of high-performance special alloy pipes and components. While renowned for its seamless products, TOKO TECH also provides ALLOY 600 (UNS N06600) welded coiled tubing, offering a cost-effective solution for high-temperature applications that require excellent oxidation resistance and mechanical strength, while benefiting from the economic advantages of the welding process and the installation convenience of long continuous lengths.
Temel Özellikler ve Avantajlar.
Mükemmel Yüksek Sıcaklık Oksidasyon Direnci. Maintains the core characteristic of ALLOY 600, forming a protective chromium oxide layer that provides outstanding resistance to oxidation at temperatures up to 1177°C (2150°F). This makes the welded coil ideal for continuous high-temperature service.
Karbürizasyon ve Sülfidasyona Direnç.Isıl işlem ve endüstriyel fırın uygulamalarında yaygın olan karbonlama ve sülfür içeren bileşikler içeren atmosferlere karşı iyi direnç gösterir.
İyi Korozyon Direnci.Çeşitli organik ve inorganik kimyasallara karşı iyi direncin yanı sıra tatlı ve alkali suların korozyonuna karşı mükemmel direnç sunar. Klorür-iyon stres-korozyon çatlamasına karşı oldukça dirençlidir.
Cost-Effectiveness: Welded tubing typically has a lower production cost compared to seamless tubing, providing an economical alternative for projects where the extreme pressure ratings of seamless tubing are not required, but core high-temperature material properties and long lengths are essential.
Continuous Coiled Length: Supplied in long continuous coils, eliminating multiple connection points and simplifying installation in complex high-temperature systems such as furnace radiant tubes and heat treatment fixtures.
Manufacturing Process & Quality Focus:
The tubing is formed from precision-rolled ALLOY 600 strip (with controlled composition: Ni ≥72%, Cr 14-17%, Fe 6-10%, C ≤0.15%), which is then longitudinally welded using advanced Tungsten Inert Gas (TIG) or Laser WeldingTemiz, yüksek bütünlüklü bir kaynak sağlamak için koruyucu atmosfer altında işlemler. Kritik bir adım daçözelti tavlama ısıl işlemi at 1038-1149°C (1900-2100°F) of the finished coil, followed by pickling & passivation. This process dissolves any carbides that may have formed during welding, restores the corrosion and oxidation resistance in the weld heat-affected zone (HAZ), and ensures a uniform, passive surface finish.
