Abstract
A pipe bend or elbow containing a cast basalt or similar lining 3, the lining being recessed over an arc of the outer periphery inside the bend or elbow to accommodate all impact resistant tile or tiles 4, or the pipe wall itself is recessed to accommodate the tile or tiles to provide a pipe having a reinforced bend or elbow. <IMAGE>
Description
SPECIFICATION
Improvements in Pipe Bends or Elbows
This invention relates to improvements in pipe bends or elbows for conveying abrasive material, and is an improvement in or modification of the invention described in our prior specification No.
1,563,784.
Specification No. 1,563,784 claims a pipe or pipe elbow for conveying abrasive or corrosive materials, comprising a ductile shell having a cast basalt lining and an elbow reinforced with impact resistant tiles grouted to a tray of mild steel plates the tray being grouted to the shell.
Although the reinforced lining was originally primarily employed for conveying pulverised fuel to power stations, it has now been found that the invention is applicable in many other fields such as ash slurries and water borne coal and the object of the present invention is to simplify the manufacture of the pipe bend or elbow and to improve its wear resistance.
According to the invention a pipe bend or elbow contains a cast basalt or similar lining, the lining being recessed over an arc of the inner periphery of the bend or elbow to accommodate an impact resistant tile or tiles or the pipe wall itself is recessed to accommodate the tile or tiles, to provide a smooth internal surface.
The invention will be described with reference to the accompanying drawings:~
Fig. 1 is a side elevation of an elbow;
Fig. 2 is a section through Fig. 1;
Fig. 3 is an elevation of one section shown in
Fig. 1;
Fig. 4 is a section on line 4-4 of Fig. 3:
Fig. 5 is a perspective view of part of the section shown in Fig. 3 to a larger scale, the outer shell being omitted.
A pipe bend or elbow 1 is formed of a plurality of segments 2 to end segments 2a and an outer shell 5 of mild steel or like material is formed with an inexpensive lining 3 of cast basalt, cast iron, cast steel, Nihard (Registered Trade Mark) to B.S.
4844, concrete or similar plastics, ceramics, glazed earthenware or the like.
The lining 3 is formed with recesses 3a to accommodate alumina or impact resistance tiles 4 of a fine grained dense sintered 96%-97.5% alumina with a ceramic bond.
The tiles 4 are arranged as segments over about 1200 of the outer circumference of the pipe but may also extend down stream of the pipe beyond the bend as excessive wear may also occur in this area.
Alternatively the pipe shell 5 itself may be made from a wear resistant material as before described and recessed to accommodate the tiles.
The tiles may be affixed in the recesses by epoxy resin or other suitable adhesive or mechanically secured therein.
Claims
1. A pipe bend or elbow containing a cast basalt or similar lining, the lining being recessed over an arc of the inner periphery of the bend or elbow to accommodate an impact resistant tile or tiles or the pipe wall itself is recessed to accommodate the tile or tiles, to provide a smooth internal surface.
2. A pipe bend or elbow as in claim 1, in which the tiles are arranged in segements over substantially 1 200 of the outer circumference of the pipe.
3. A pipe bend or elbow as in claims 1 or 2, in which the tiles extend downstream of the bend.
4. A pipe bend or elbow substantially as described with reference to the accompanying drawings.
New Claims or Amendments to Claims filed on 26 Sex 1980.
Superseded Claims 1 to 4.
New or Amended Claims
1. A pipe bend or elbow for conveying abrasive or corrosive materials comprising an outer shell, a lining of cast basalt and tiles of fine grained dense sintered alumina ceramic arranged as segments over substantially 1200 of the outer circumference of the pipe and secured to the basalt lining by an epoxy resin, the lining being recessed to accommodate the tiles to provide a smooth internal surface.
2. A pipe bend or elbow as in Claim 1 in which the tiled segment is extended down stream of the bend.
3. A pipe bend or elbow for conveying abrasive or corrosive material substantially as described with reference to the accompanying drawings.
**WARNING** end of DESC field may overlap start of CLMS **.
Claims (4)
1. A pipe bend or elbow containing a cast basalt or similar lining, the lining being recessed over an arc of the inner periphery of the bend or elbow to accommodate an impact resistant tile or tiles or the pipe wall itself is recessed to accommodate the tile or tiles, to provide a smooth internal surface.
2. A pipe bend or elbow as in claim 1, in which the tiles are arranged in segements over substantially 1 200 of the outer circumference of the pipe.
3. A pipe bend or elbow for conveying abrasive or corrosive material substantially as described with reference to the accompanying drawings.
3. A pipe bend or elbow as in claims 1 or 2, in which the tiles extend downstream of the bend.
4. A pipe bend or elbow substantially as described with reference to the accompanying drawings.
New Claims or Amendments to Claims filed on 26 Sex 1980.
Superseded Claims 1 to
4.
New or Amended Claims
1. A pipe bend or elbow for conveying abrasive or corrosive materials comprising an outer shell, a lining of cast basalt and tiles of fine grained dense sintered alumina ceramic arranged as segments over substantially 1200 of the outer circumference of the pipe and secured to the basalt lining by an epoxy resin, the lining being recessed to accommodate the tiles to provide a smooth internal surface.
2. A pipe bend or elbow as in Claim 1 in which the tiled segment is extended down stream of the bend.
