China Petroleum Fittings Manufacturer, Supplier, Factory


Overview:

Petroleum Fittings are key components used in the oil and gas industry for connecting pipeline systems and controlling the flow of fluids, covering a wide range of fittings, valves, converters, etc. They are mainly used for connection, steering, branching and pressure control of pipeline systems to ensure the safe and efficient transmission of fluids (crude oil, natural gas, etc.) in complex pipeline networks. Its functions include: connection and sealing, connecting different pipe sections by welding, threading, etc. to prevent leakage (e.g. flanges, coupling joints). Flow control, changing the direction of fluid (e.g. elbows, tees) or diverting the flow (e.g. crosses). Pressure regulation, controlling flow and pressure through components such as valves.


Application Areas:

Oil and gas transportation: Connection and distribution in long-distance oil/gas pipeline networks.

Refining and chemical facilities: Process piping systems within refineries, chemical plants.

Storage and Handling: Tank and ramp piping connections for oil depots and airport fuel supply systems.


Standardization and materials:

International standards: ISO 15590-2 and other standardized technical delivery conditions, distinguishing between conventional and acidic environment use categories.

Material Selection: Carbon steel, stainless steel mainly, some need to meet the requirements of high strength or corrosion resistance.
