The Production Wellhead Device is comprised of three components, which
                                      including Casing Head, Tubing Head and Christmas tree. They are mainly used
                                      for production well to control pressure and adjust flow rate of oil (gas) well.
                                      They are also available for controlling Wellhead during acid fracturing, water
                                      injection and well performance test. During of PSL1 to PSL3, they can meet AA、
                                      BB、CC、DD 、EE working condition’s requirement.

                                      The bearing part of the device is made of low alloy steel through heating treatment
                                      with high bearing capability and high reliability and safety. According to various
                                      working condition, the material of sealing elements include Propyl Cyanide,
                                      Hydrofluoric, Teflon, Tetrafluoride, Austenitic Stainless Steel with high corrosion
                                      resistance and perfect sealing property.
