The main advantages of grooved pipe fittings, also called clamp connection, are as follows:

1. Quick to take the groove clamp contact and the corresponding pipe fitting placement pipeline, do not need to weld, do not need to two galvanized, two placement. Increased placement rate.

2. Light clamp contact light weight, fewer bolts, convenient placement, do not need special skills.

3. Reliable, scientific and reasonable organ planning, unique C-type rubber sealing ring, triple sealing, to ensure the reliability of the connection seal.

4. Safe with the groove clamp contact and the corresponding pipe fitting placement, only mechanical assembly, no welding, no open fire, therefore, no welding slag turbidized pipeline, can ensure the safety of the site, the construction of fire prohibition conditions, especially suitable.

5. Due to fast placement, no special skills required and low placement and repair rate, the comprehensive placement cost can be reduced by 30-50% compared with France.

6. The space occupied by the small groove type clamp connection occupies about 70% of the space of the flange, and because the number of fastening bolts is small and non-objective, it is especially practical to start construction under the condition of narrow space.
