Les barres de forage, ou drill rods en anglais, jouent un rôle crucial dans l'industrie de l'exploration minière et pétrolière. Elles constituent un élément essentiel des équipements de forage, permettant de percer le sol et d'atteindre les profondeurs nécessaires pour explorer les ressources naturelles. Dans cet article, nous examinerons les différents types de barres de forage, leurs matériaux, ainsi que leur importance et leur application dans l'industrie.

  • Oil seals, often made from high-quality rubber compounds or synthetic materials, are designed to prevent the leakage of lubricants while inhibiting the ingress of contaminants. The 8 in the name likely refers to the percentage of oil-resistant material used in the seal's construction, enhancing its ability to withstand exposure to various oils and lubricants without degradation.

  • Double oil seals are commonly used in high-pressure and high-speed applications where maintaining a clean and uncontaminated environment is crucial. Industries such as automotive, aerospace, petrochemical, and heavy machinery manufacturing all benefit significantly from this technology Industries such as automotive, aerospace, petrochemical, and heavy machinery manufacturing all benefit significantly from this technology Industries such as automotive, aerospace, petrochemical, and heavy machinery manufacturing all benefit significantly from this technology Industries such as automotive, aerospace, petrochemical, and heavy machinery manufacturing all benefit significantly from this technologydouble oil seal. For instance, in automotive engines, double oil seals ensure that engine oil stays within the system, preventing oil leaks that could lead to engine failure or environmental pollution.
  • Nitrile (NBR): The nitrile rubber or nitrile provides excellent resistance to numerous oils and greases, including mineral grease and hydraulic oil. There are several synthetic lubricants and greases in the market based on glycol which may cause harm to NBR rubber compounds depending on their composition. Due to their excellent durability and cost-effectiveness, these seals are used in a wide range of operating conditions. However, NBR is unable to withstand exposure to acids and solvents.
  • In addition to helping ignite the fuel in certain conditions, the spark plug also plays a role in maintaining the proper temperature of the combustion chamber

  • The primary material, rubber, offers exceptional flexibility and resilience. It can conform to irregular surfaces, seal tightly, and maintain its seal even under varying temperatures and pressures. Rubber edge gaskets are designed with a specific type of rubber, each tailored to suit different environmental conditions and chemical resistances. For instance, silicone rubber gaskets are ideal for high-temperature applications, while neoprene gaskets excel in resisting oils and chemicals.
