O&G Pipeline Commissioning Procedure (& Pre - NiGenNov 19, 2019 · Flushing out natural gas lines can be done with the help of mechanical devices (pigging) or chemically by forcing chemical compounds through the pipeline channels. Pigging During a pigging operation , a device called a pig is driven through the interior of the pipeline system to clean it and flush out retained impurities.
PE 607:Oil & Gas Pipeline Design, Maintenance & Repair 15 CONNECTING PIPES Pipes available in sections or segments* of 20-ft length. For steel pipes, the maximum section length is usually 40 ft. Segments transported to the construction site Before being laid in ditches, sections joined (connected) together to form a long pipeline PIPELINE PIGS - NACE Houston SectionCHEMICAL BATCH PIGGING In a dry gas pipeline, batch pigging involves running a batch of oil soluble inhibitor or biocide ahead of a single pig; or between two pigs so that the whole internal pipe surface is wetted. In a liquids pipeline, batch pigging can be used to separate products by reducing the interface between products.

They are mainly used to run petroleum or natural gas pipelines, or cable trays over a river, gorge, highway, or other obstacles. A pre-engineered modular pipe rack is the main artery of a process
Pipeline pickling is the process of conditioning a new gas pipeline before putting it into service. In new gas lines, it is common to experience odor fade in gas as the natural gas odorant reacts with rust and mill scale inside new steel pipes, thereby producing less odorous compounds. The process of conditioning the line ensures the safe Pipe and Pipeline Inspection ServicesPipe Inspection during Manufacturing As new line pipe is rolled and/or fabricated, inspection is important to ensure no faulty pipe and materials are installed. Inspections can be at the place of manufacture or at material receipt. Intertek helps in ensuring that all pipe produced meets your requirements and conforms to accepted standards.

Jan 01, 2005 · Purging with gas. This method is seldom used for pipeline cleaning, because the amount of debris that will be removed is small. A high gas velocity is required. Pipeline drying Pipelines used to transport petrochemicals such as pro- pylene and ethylene must be dried in order for the delivered product to meet moisture specifications. Pipeline InspectionThe pipe is vulnerable to attack by internal and external corrosion, cracking, third party damage and manufacturing flaws. If a pipeline carrying water springs a leak bursts, it can be a problem but it usually doesn't harm the environment. However, if a petroleum or chemical pipeline leaks, it can be a environmental disaster.
Two types of corrosion can occur in oil and gas pipeline systems when CO2 and H2S are present in the hydrocarbon fluid:sweet corrosion and sour corrosion.Sweet corrosion occurs in systems containing only carbon dioxide or a trace of hydrogen sulfide (H2S partial pressure < 0.05 psi).
