They are widely used in joint corrosion prevention, leakage prevention, protection of petroleum, natrual gas and heat insulation pipelines, etc. They are predominant in high mechnical strength, strong anti-aging capability, good sealing property, corrosion resistance, convenient construction, etc. Application:1. For girth welding of pipeline 2. Composite Contends with Arctic Conditions in Underwater A diver applied SnapWrap to address corrosion on multiple girth weld joints on a 10-inch (254- mm) underwater gas pipeline. The water temperature at the work site was 43°F (6°C) The diver installed the SnapWrap composite sleeves, working with zero visibility. A new tool was designed to allow the diver to install long sleeves without assistance.

Company History. Known as a leader in the industry, the Kingdom has witnessed major developments in the pipeline industry. To meet the demands of the harsh environment and for protection of cross-country and sub-sea oil, water and gas pipelines against corrosion the Al-Qahtani Pipe Coating Terminal was established in 1945. What are Tape Coatings? - Definition from CorrosionpediaAug 31, 2017 · They are applied along the length of the pipes. They are mostly used in the pipeline (gas, oil, water and solvent waste) and marine industries to provide a protective shielding against cathodic corrosion and waterproofing on girth weld joints and fittings depending on the surrounding environmental conditions and climate.

What is a Girth Weld? - Definition from Corrosionpedia

Aug 16, 2015 · Girth welds are the different types of arc welding processes applied in the joining of two pipes along the circumference during a phase construction of a pipeline depending on the ease of implementation and the environmental factor. They are used in making circumferential welds in pipeline and underground systems. girth welding - English definition, grammar, pronunciation The apparatus is particularly suited to coating girth welds of a pipeline. patents-wipo The heat recoverable polymer material can include a surface having an adhesive coated thereon disposed on the girth


PURPOSE OF GIRTH WELDS Girth welds allow the connection of standard 40 or 80 long sections of coated pipe into longer lengths required to build a pipeline. Longer sections create transportation problems. Each 100 miles of pipeline can contain up to 13,200 girth welds.
