Abstract
A fire protection sprinkler system and method of monitoring corrosion in a fire protection sprinkler system that includes a pipe network and at least one sprinkler connected with said pipe network. A corrosion monitor assembly is provided in the pipe network that includes at least one metal coupon and an oxygen depletion area defined on a surface portion of the coupon. A mounting member positions the corrosion monitor assembly to be at least partially covered with water when the sprinkler system is in an operative state.
Claims26
A fire protection sprinkler system, comprising:
- a pipe network and at least one sprinkler connected with said pipe network;
- and
- a corrosion monitor assembly in said pipe network, said corrosion monitor assembly comprising at least one metal coupon and a layer of non-metal material defining an oxygen depletion area on a surface portion of said at least one metal coupon;
- and
- a mounting member that positions said at least one metal coupon and said layer of non-metal material to be at least partially covered with water in said pipe network when said sprinkler system is in an operative state.
The sprinkler system as claimed in 1 wherein said non-metal material comprises a polymeric material.
A fire protection system corrosion monitor assembly for use in a fire protection sprinkler system having a pipe network and at least one sprinkler connected with said pipe network, said corrosion monitor assembly comprising:
- at least one metal coupon having a size and shape that is configured to fit within the pipe network;
- a layer of non-metal material defining an oxygen depletion area on a surface portion of said at least one metal coupon;
- and
- a mounting member that positions said at least one metal coupon and said layer of non-metal material to be at least partially covered with water when said sprinkler system is in an operative state.
A method of monitoring corrosion in a fire protection sprinkler system having a pipe network and at least one sprinkler connected with said pipe network, said method comprising:
- providing a corrosion monitoring assembly comprising at least one metal coupon having a size and shape that is configured to fit within the pipe network and a layer of non-metal material defining an oxygen depletion area on a surface portion of said at least one metal coupon;
- and
- positioning said corrosion monitoring assembly in the pipe network in a manner that said at least one metal coupon and said layer of non-metal material are at least partially covered with water when said sprinkler system is in an operative state.
The method as claimed in 13 wherein said non-metal material comprises a polymeric material.
A fire protection sprinkler system, comprising:
- a pipe network and at least one sprinkler connected with said pipe network;
- and
- a corrosion monitor assembly in said pipe network, said corrosion monitor assembly comprising at least two metal coupons and a layer of non-metal material between said coupons, the layer of non-metal material defining an oxygen depletion area between the layer of non-metal material and one of the at least two metal coupons;
- and
- a mounting member that positions said at least two metal coupons and said layer of non-metal material to be at least partially covered with water in said pipe network when said sprinkler system is in an operative state.
A fire protection system corrosion monitor assembly for use in a fire protection sprinkler system having a pipe network and at least one sprinkler connected with said pipe network, said corrosion monitor assembly comprising:
- at least two metal coupons having a size and shape that is configured to fit within the pipe network;
- and
- a layer of non-metal material between said coupons, the layer of non-metal material defining an oxygen depletion area between the layer of non-metal material and one of the at least two metal coupons;
- and
- a mounting member that positions said coupons and said layer of non-metal material to be at least partially covered with water when said sprinkler system is in an operative state.
A method of monitoring corrosion in a fire protection sprinkler system having a pipe network and at least one sprinkler connected with said pipe network, said method comprising:
- providing a corrosion monitoring assembly comprising at least two metal coupons having a size and shape that is configured to fit within the pipe network and a layer of non-metal material between said coupons, the layer of non-metal material defining an oxygen depletion area between the layer of non-metal material and one of the at least two metal coupons;
- and
- positioning said corrosion monitoring assembly in the pipe network so that said coupons and said layer of non-metal material are at least partially covered with water when said sprinkler system is in an operative state.
