1. A heat exchanger, especially for a gas or oil heated water heater, comprising at least one outer tube (11) conducting a first heat transfer medium and through which extends at least one inner tube (31) smaller in diameter for a second heat transfer medium which is in heat exchange rel...
Gasoline, the fuel used in most vehicles today, is a refined product made from crude oil. Despite the shortened "gas" being used for when you're at the pump, it is different from natural gas, which you may use to heat your home, dryer, or stovetop. The Bottom Line Oil is one of ...
while crude oil prices reflect global conditions, natural gas prices are more geographic and specific to seasons. While Europe's gas prices rose, the U.S., the world's largest natural gas producer, was relatively insulated from supply disruptions in Europe. ...

Under the action of the thermal welding cycle, due to the change of structure and properties of the weld and heat-affected zone, coupled with the influence of stress and diffusible hydrogen, cracks may occur. Especially with the increase in pipeline strength level (such as ×80 grade pipeline...
Meanwhile, the heat released from the oxidation reaction during air flooding causes thermal expansion of the oil along with the bond-breaking reaction of the oil, thus forming a flue gas front which results in better displacement effects in low permeability reservoirs [16,17]. Nevertheless, the ...
