    摘要: A device for and method of testing fluid compatibility may include placing a first fluid in a fixed-volume testing chamber and placing a second fluid in a sample chamber. The method may also include heating the fixed-volume testing chamber to about a temperature of a subterranean environment and pressurizing the fixed-volume testing chamber to about a pressure of the subterranean environment. The method may further include determining, at a temperature and pressure of about the temperature and pressure of the subterranean environment, a first rheology value of the fluid within the fixed-volume testing chamber, moving a portion of the second fluid from sample chamber into the fixed-volume testing chamber, and determining, at a temperature and pressure of about the temperature and pressure of the subterranean environment, a second rheology value of the fluid within the fixed-volume testing chamber.

    摘要: A gate valve has a body, the body having a cavity and a flow passage intersecting the cavity. A seat is mounted to the body at the intersection of the flow passage and the cavity. A gate is installed at the cavity and has an engaging face that slidingly engages the seat while the gate is being moved between open and closed positions. The end faces between a seat pocket and the seat are hard-coated and smooth-finished to provide sealing when mated. The hardcoated pocket and seat sealing surfaces extend the life of the valve by eliminating the need for an elastomeric seal of limited life.
