Gas pipe bondingFocuses on a United States rule for bonding gas piping systems. Concern of the electric and gas industries; Resulting debate on how big does the bonding conductor need to be; National Fuel Gas Code.Hartwell, Frederi...
During the last decades, the worldwide demand for transportation fuels with a quality that satisfies environmental regulations has increased. At the same time, the availability of light crude oil has undergone a decline, which has gradually been offset by heavy crudes (Alvarez and Ancheyta, 2009...
Gas pipe bondingYou need to size bonding conductors to gas piping the same as those for water pipes and structural steel -even though they aren't used as electrodes.Frederic P. HartwellEC&M
PURPOSE: A bonding gun for joining polyethylene gas pipes is provided, to join the joining part of polyethylene gas pipes and to bond the defected part of a polyethylene gas pipe for preventing the breakage of a gas pipe due to earth pressure. CONSTITUTION: The bonding gun(100) comprises a...
Method and apparatus for bonding under pressure, a lining in a pipe, in particular in a distribution conduit of gas old buriedA lining 1, pre-glued internally is unwound of a coil 2 and is introduced through a pressure chamber 5 and by a control group in a pipe 14. The end front of...
Due to the bonding of solid particles, there is a serious problem of gas-solid flow pipe and conduit blockage in a large number of processing industries. In response to this problem, the paper uses specialized simulation tools (ANSYS R16.0 FLUENT) to study the effects of gravity on the flow...
Hydrogen bonding has a significant impact on the thermodynamic nature of inhibitors. Hydrogen bonds can easily develop between water molecules and ionic liquids. Therefore, when ionic liquids come into contact with hydrates, the water molecules in the hydrates create hydrogen bonds with the ionic ...

ASTM G8-96; Standard Test Methods for Cathodic Disbonding of Pipeline Coatings. ASTM International: West Conshohocken, PN, USA, 2019. Wood, R.J.K.; Wharton, J.A.; Bello, J. Evaluation of the Adhesive Properties of Downhole Corrosion Resistant Polymeric Coatings Determined by Cathodic Disbond...
The cathodic disbonding test apparatus includes an electrolytic cell, potentiostat, and voltage meter. Torque Testing of External Coatings The integrity of the external coating is essential to withstanding the downhole envi- ronment temperature, water salinity, and chemical compatibility. However, the ...
