In August 2016,Centrifugally Cast tubes Duplex Stainless Steel SAF2205,totally 8 sets,were delivered to Australia by air.
This series of cast tube products include Liner Throat, Wear Ring, Seat Ring.
1.We adopted centrifugal casting process to make the tubes.
Firstly,casting a whole long tube, 1800mm long;
Secondly cut into 4 sections , 400mm long each;
Thirdly followed by solution treatment.
It is not an easy job.As the length of the tube is long, there is a certain angle in the inner wall, and 2205 material is relatively soft, easily deformed. We made efforts on special tooling to overcome the deformation of the tubes during machining process.
2.The weight of this tube is about 70kg. The tubes have passed X-ray inspection;Chemical composition and mechanical properties have passed a third-party laboratory examination.
3.For duplex steel workpiece Liner Throat, size: OD435 x ID398 x 365, we have carried out a solution treatment to enhance the strength of the material and to ensure that the stress is fully relieved.
