Patent ID: 7997303

Claim:
A pipe segment for transporting a hot particulate material in a carrier gas in a transfer line, which said pipe segment includes: (a) an outer pipe, section; (b) an inner pipe section defining a passageway for a hot particulate material and a carrier gas, the inner pipe section being positioned within the outer pipe section, and the inner pipe section being formed from or having an inner lining of an abrasion resistant material; and (c) a support means supporting the inner pipe section in relation to the outer pipe section so that the inner pipe section can expand axially relative to the outer pipe section in response to temperature changes in the material being transported in the pipe segment, the support means including a first support means located at one end of the pipe segment, the first support means including a support member that can receive an end of an inner pipe section of an adjacent pipe segment when the adjacent pipe segment is positioned in use in end to end relationship with the said pipe segment and can allow axial expansion of that inner pipe section relative to the outer pipe section of the said adjacent pipe segment in response to temperature changes in the material being transported in the said adjacent pipe segment, wherein the support member is directly connected only to the outer pipe section of the said pipe segment.
