High Sulfur-Resistant and High Pressure Wellhead & Christmas Tree Solution
•We provides comprehensive solutions for high-sulfur and high-pressure wellhead equipment and gas recovery trees with its high-resistant sulfur HH-level wellhead
equipment, large-diameter fracturing trees, 140MPa casing heads, 140MPa fracturing gas production wellheads, and other products.
In recent years, China's oil and gas exploration and development has become increasingly advanced
, encountering geological conditions that are becoming more complex and generally featuring deep
reservoirs, high temperatures, and high production rates, as well as containing hydrogen sulfide and
carbon dioxide corrosive gases. These acidic gas deposits cause severe corrosion to the equipment on
the well site and require equipment that can withstand high impact wear. Conventional wellhead
devices are difficult to meet these oil and gas production requirements. Materials used for high-sulfur-
resistant wellheads are all special corrosion-resistant materials and adopts super nickel-based alloy
flow channel welding technology. They use full-metal sealing devices suitable for high-pressure
, corrosion-resistant, and harsh working conditions, which maximizes the safety of the wellhead
operation. With super nickel-based alloy flow channel welding technology, hard-surface spraying
technology, and polishing technology, 140Mpa gas-tight sealing can be achieved, and a true full-metal
sealing device can be used for high-pressure, corrosion-resistant, high-displacement, and sand-proof
working conditions. Equipped with a safety valve and wellhead control cabinet, the well can be shut
down within 5 seconds at the fastest, maximizing the safety of the wellhead operation.
