Pipe Pickling or Pickle Gas Pipeline to Solve Odor Fade

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.

Pipeline Drying - ScienceDirect

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.
