Distribution courses in the eWebOQ® Distribution Library address a wide range of pertinent distribution line topics, from plastic pipe fusion to installation of residential and commercial meters and regulators.
*Includes Performance Checklist
Addresses natural gas odorization and its regulation, distribution systems, class determination, testing, recordkeeping, odorometer operation and maintenance, and safe handling and storage.
Examines types of plastic pipe used in the heat fusion process, principles of heat fusion, the heat fusion process, inspection and testing of fused joints, safety precautions when handling polyethylene pipe, hazards of static electricity, and spark prevention.
Examines types of plastic pipe used in the electrofusion process, basic principles of electrofusion, the electrofusion process, inspection and testing of fused joints, safety precautions when handling polyethylene pipe, hazards of static electricity, and spark prevention.
Examines Lycofit® fittings, joining plastic pipe with mechanical fittings, and installation of various kinds of couplings.
Teaches the user how to: determine present system and facilities conditions, review proposed up-rate pressures, understand and write an up-rate plan, determine system conditions prior to pressure increases, and maintain required up-rate records.
Addresses precautions and practices for handling and storing plastic pipe, installation of plastic pipe for natural gas main and service lines, installation of transition fittings, installation of excess flow valves, abandonment and reinstatement of mains and services, and installation of tracer wire.
Addresses direct burial of plastic pipe; tie-ins and tapping service punch tees; squeezing plastic pipe, including the squeeze-off procedure; inserting plastic pipe in an existing line; pressure testing mains and services; purging mains; and repairing PVC pipe.
Examines general safety precautions for natural gas operations and maintenance; testing for gaseous or oxygen-deficient atmosphere; lock-out and tag-out of gas valves; trenching and excavation safety guidelines; hazards of directional boring; traffic management, including traffic control zones; hazards of static electricity, including possible ignition; and the Hazard Decision Tree Analysis.
Addresses proper handling, storage and inspection of steel pipe; typical right-of-way and easement requirements, including pipeline depth and clearance from other underground structures; pipe installation requirements for overhead and underground highway, railroad, stream, river, and levee crossings; pipeline installation, including joining pipe by welding or with fittings, lowering-in, pressure testing, and backfilling the excavation; and stell Distribution Service line installation, connection to curb valves, and connection to the main tapping.
Designed for gas transmission and distribution participants. This course addresses tie-in considerations regarding job planning, safety, equipment, materials and manpower; tie-in procedures, including line shutdown, purging, welding, pressure testing, required fittings, and returning the pipeline to service; tie-in configuration connections; and installation of one-and two-piece control fittings, steel-to-plastic transition fittings, curb and service valve tees, three-way tees, tapping and drilling, and stopping procedures for steel pipe.
Examines the requirements for atmospheric corrosion control. This course addresses the corrosion process; surface preparation; attributes of and risk factors for atmospheric corrosion; and protective methods used to control atmospheric corrosion.
Examines the basic parts of a residential gas distribution system; installation of meters and regulators; protecting a residential gas system from pressure damage; meter and regulator selection; installation of a meter set and adjusting a meter’s set point; testing for gas system leaks; and service wrap-up procedures.
Addresses the basic parts of a commercial gas distribution system; installation of meters and regulators; protecting a commercial gas system from pressure damage; meter and regulator selection; installation of a meter set and adjusting a meter’s set point; testing for gas system leaks; and service wrap-up procedures.
