Pipes can be joined by three basic methods: 1. mechanical, 2. _____________ and 3. __________________. Both the mechanical and 4. _______________ methods can be further divided. The former method includes 5. _____________ and 6. ______________. The latter method can be broken down into
7. ________ and 8. _____________.
Match the methods with the description.
Example: 6 – C
| 1. | threaded | A. | joining light-wall steel and copper pipe, metallic or nonmetallic that is being cut or rolled |
| 2. | welded | B. | consist of an inner elastometric gasket and an outer metallic sleeve with integral bolts for compressing the gasket. |
| 3. | soldered | C. | a substance that hardens under heat to bond pipes |
| 4. | crimped (grooved) | D. | pressure-type joint made with a filter metal that, when heated to its melting point, is drawn into the annular space between pipes and fitting by capillary action. |
| 5. | compressed | E. | is a metal-joining process wherein coalescence (соединение) is produced by heating to suitable temperatures with or without the use of filler metal. |
| 6. | cemented | F. | a continuous helical (винтовое зубчатое колесо) has threads on each end, making it possible to screw two pieces of pipe together. |
