Embodiment Construction

[0020]Design of Riser tube stalk consists of following components

[0021](1) Neck; it is shapped to match various casting machine designs and is part of the main body of riser tube. Neck-less design is also adopted when interagted flange (3) is designed within the main body (4) of the Riser tube stalk.

[0022](2) Sealing slots; Feature provided in the form of slots to hold sealing material between metallic and ceramic parts of the riser tube. Mechanical sealing is achieved by using very high temperature sealing compounds. The sealant has working temperatures of over 1200° C. and is shapped to the slot profile. Shape and quantity of slots vary according to level of sealing required. Some riser tubes may not require sealing slots where a different type of sealant can be applied in the form of expansion filler (10).

[0023](3) Integrated flange; The flange is an integrated feature of this design. It can be of any dimension in shape, diameter and height. Since the flange is cast or machined w...

Abstract

The invention Ceramic Metal Riser Tube stalk is designed to countermeasure the problems caused by the use of conventional riser tubes. The subject matter uses metals and ceramics combination therefore achieving properties of both materials. The invention reduces safety risks of Riser tube replacement, down time, reduces losses caused by casting defects and it is economical to manufacture. Components of the subject matter can be reused for further economic benefits.
