| 英文 | 中文 | 英文 | 中文 | |
| AMERICAN_MECHANICAL_JOINT | American Mechanical Joint | An American Mechanical Joint is a rubber gasket is compressed by a ductile iron gland drawn up with low-alloy steel bolts which affords liberal deflection and allows expansion and contraction of the line without leakage and is rated for a water working pressure of up to 350 psi. | ||
| BELLED | Belled | The end length of increased diameter into which a pipe end can be fitted. | ||
| BUTT | Butt | The connection is a flat cut end designed to mate directly to the end of another product. This connection is to connect the same sized pipes or valve ends together. | ||
| COMPRESSION_JOINT | Compression Joint | A compression joint kind of tubing or pipe connection where a nut, and then a sleeve or ferrule is placed over a copper or plastic tube and is compressed tightly around the tube as the nut is tightened, forming a positive grip and seal without soldering. Also a flexible compression fitting. | ||
| CRIMPED | Crimped | This type of joint requires the joint be crimped once sections are fit together. Some of the necessary connection parts must be added or acquired separately. | ||
| FEMALE_THREADED | Female Threaded | Female threaded | ||
| FLANGED_JOINT | Flanged Joint | Flange generally refers to the actual raised rim or lip of a fitting which can be bolted to the flange of an opposite unit. | ||
| FLARE_JOINT | Flare Joint | A Flare Joint is where a pipe or tube is widened to join with a larger diameter pipe, for example between a copper tube and a main water feed line. | ||
| GROOVED_JOINT | Grooved Joint | Outer diameter of item has a groove which is designed to be joined together using external gaskets and couplings. | ||
| LUG | Lug | The lug body has protruding lugs that provide bolt holes matching those in the flanges. An advantage of the lug body type is that piping on one side of the valve may be disassembled while the valve remains bolted in place, allowing for the remainder of the system to continue in operation. | ||
| MALE_THREADED | Male Threaded | Male Threaded | ||
| MECHANICAL_JOINT | Mechanical Joint | A Mechanical Joint is a joint which typically consists of: (a) a flange which is integrally cast with the bell of the pipe, (b) a rubber gasket which fits into the recess in the socket, (c) a follower ring which compresses the gasket, and (d) nuts and bolts used to tighten the joint. | ||
| NO_HUB_IRON | No Hub Iron | A connector for no-hub iron pipe consisting of a rubber sleeve and a stainless steel band secured by hose clamps. A variation, a neoprene sleeve with two adjustable steel bands, is used for connecting dissimilar materials, as when connecting new plastic pipe to an existing cast iron drain pipe. | ||
| PACK_JOINT | Pack Joint | Pack Joint | ||
| PLAIN | Plain | SPG - Spigot, FTG- Fitting, M- Male Pipe Size- Straight end to connect or insert into the bell end or fitting to join to connecting pipe. | ||
| PRESS | Press | This type of joint requires the joint be crimped once sections are fit together. All of the necessary connection parts are present. | ||
| PUSH | Push | A joint which can be pushed onto the opposite end manually to form a solid connection. This type of connection fits around an inserted pipe or fitting end. | ||
| QUICK_CONNECT | Quick Connect | A connection which has the ability to joined and un-joined repeatedly or at will. This type of joint does not degrade the product over time. This type of joint is not considered by the industry to be a push joint. | ||
| SOCKET | Socket | The connection is a female socket end designed to allow for the insertion of straight pipe/tubing and joined using soldering, sweating, brazing, welding, or cementing. This connection is also called solder cup, hub, or slip joint. | ||
| SWIVEL_JOINT | Swivel Joint | This type of joint uses a pressure type seal while allowing rotation of the units being joined. | ||
| UNION_JOINT | Union Joint | This type of joint can connect and disjoint two pipes very easily without deformation to the pipe or tube. | ||
| WAFER | Wafer | A wafer is a seal using a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve. | ||
| YOKE_JOINT | Yoke Joint | A connection whereby a piece is expanded on one end into a seal face to form a joint. | ||
