Abstract
A method of replacing pipe couplings is provided. The couplings, such as elbow joints, “T” couplings, “Y” couplings, etc., have a traditional conduit construction including tubular end sections which telescopically connect to pipe ends. The couplings are removed by cutting the pipes adjacent to the couplings tubular sections so that the pipes have a reduced length. A replacement coupling is connected to the pipe ends. The replacement coupling has tubular sections which are extended to have an increased length “L”. The increased length allows the replacement coupling to mate to the respective pipes even though the pipes have a shortened length than prior to removal of the replaced coupling.
Claims11
A method of replacing a pipe coupling comprising the steps of:
- providing a pipe joint including a first coupling having at least a first tubular input section having a length and a second tubular input section having a length, said pipe joint further including a first pipe telescopically joined to said first tubular input section and a second pipe telescopically joined to said second tubular section;
- providing a second “replacement” coupling including a first tubular input section having a length greater than the length of said first coupling's first input section and a second tubular input section having a length greater than the length of said first coupling's second input section;
- removing said first coupling from said pipe joint by cutting said first pipe adjacent to said first coupling and by cutting said second pipe adjacent to said first coupling wherein said first pipe is shorter than prior to said cutting and said second pipe is shorter than prior to said cutting;
- and
- after removing said first coupling from said pipe joint, coupling said first and second pipes together with said replacement coupling by telescopically joining said replacement coupling's first tubular input section to said first pipe and telescopically joining said replacement coupling's second input section to said second pipe to form a pipe joint.
