Testing Steel Pipe Sample Clauses

Testing Steel Pipe. When a section of pipe of a length deemed adequate by the Engineer is ready for testing, the line shall be thoroughly cleaned by forcing a “pig” through the pipe a sufficient number of times to remove foreign matter which may have been trapped inside the pipe during construction. After cleaning, all new mains shall be proved to be gas tight by an appropriate pressure test. The Engineer or Owner may require the Work to be divided into convenient sections for testing. All test segments shall be backfilled throughout its entire length before starting the test, except for necessary bell holes and open valve settings as approved by the Engineer or Owner. The Contractor shall furnish all labor, materials and equipment for carrying out these tests. All tests shall be conducted in the presence of the Engineer or his representative.
