KQ Series Sulfide-resistant Gas Production Wellhead Equipment The KQ Series wellhead equipment consists of bottom flange, upper flange, tubing head, gate valve, needle valve, small cross, stop valve and meter etc. It is mainly used for production wellhead to control pressure and for the oil(gas)wellhead to adjust flow rate; It is also available for controlling wellhead during the acid fracturing, water in ejection and well performance test. Principal Features:1、All pressurized parts and flanges on the wellhead equipment are made of high-grade alloy steel by press forging, which are also subject to non-destructive texts to ensure safety: 2、Rams and valve seats as well as needles of needle valves are manufactured with built-up or sprayed welding; 3、Key components are sulfide-resistant after heat treatment; 4、The sealing parts are made of sulfide-resistant materials, such as polytetrafluoroethylene (PTFE) and fluoro-rubber; 5、Simple in construction, light in weight and reliable in performance.
