Abstract

815,192. Pipe joints. FOXBORO CO. May 7, 1957 [May 11, 1956], No. 14557/57. Class 99(1). [Also in Group XXXVI] A device such as electromagnetic flow sensing unit 10 mounted on a pipe 11 is inserted in a pipe line 12 by a joint wherein a pipe end of the device is formed with a flange collar 30 having a peripheral screw-thread on which is screwed an assembly ring 31. The device is placed on the pipe 11 and the ring screwed on, the possibility of damage being avoided to the device as may occur when flanges are welded on in the usual manner. The unit 10 comprises a coil assembly 13 formed of two major windings 14, 15 placed edge to edge and connected by a strap 16. The coil assembly 13 has an inner diameter greater than the outer diameter of pipe 11 and is supported by U-channel brackets 17, 18 to which the windings 14, 15 are connected by straps 21, 22 and bolts 19, 20 the brackets 17, 18 being secured to the pipe 11. The assembly is protected by a split cover 23 which fits over the pipe 11 with suitable O-rings 25 to seal out dirt and moisture and is secured by bolts 26. Electrical leads are taken through a boss 27 on the cover 23. The pipe 11 and brackets 17, 18 are of non-magnetic material e.g. stainless steel and within the pipe 11 an electrically insulated lining sleeve 29 is provided which may be made of rubber, synthetic plastic &c., or a material which may be sprayed and is chemically and physically inert to the liquid flow. The rings 31 may be rotated for alignment of the bolt holes for easy assembly and disassembly of the device.
