Grooved Flexible Coupling for Fire Sprinkler System

Groove pipe fittings include two major categories of products:

(1) the connection sealing effect of the pipe fitting has a rigid joint, flexible joint, mechanical tee and groove flange;

(2) to connect the transition role of the pipe elbow, tee, tee, reducing pipe, blind plate, etc.

As an advanced way of pipe connection, trench fitting connection can be either explicitly or embedded, with both rigid and flexible joints.Therefore, it has a wide range of application.

(1) according to the system: can be used for fire water system, air conditioning hot and cold water system, water supply system, petrochemical pipeline system, thermal and military pipeline system, sewage treatment pipeline system;

(2) according to the pipe material: can be used to connect steel pipe, copper pipe, stainless steel pipe, lined steel pipe, ductile iron pipe, thick wall plastic pipe and with steel pipe joint and flange joint hose and valves.

Nine big advantages

1, quickly take the groove clamp contact and the corresponding pipe fitting placement pipeline, start construction do not need to be welded, do not need to be twice galvanized, twice placement.Increased placement rate.

2, light weight of contact clamp, bolt number is small, easy placement, do not need extra skills.

3, reliable scientific and fair mechanism design, peculiar c-type rubber seal ring, triple seal, guarantee the reliability of the connection seal.

4, peace with the trench clamp contact and the corresponding pipe fittings placement start, only mechanical assembly, no welding, no open fire, therefore, there is no welding slag muddy pipeline, can ensure the site safety, for the fire conditions of the construction, especially suitable.

5, the economy because the placement is fast, do not need extra skills, placement repair rate is low, so the comprehensive placement cost than flange can save 30-50%.

6, take up space small groove type clamp contact connection space is about 70% of the flange, and due to the number of fastening bolts and no object, especially practical space under narrow conditions of construction.

7, the maintenance of a brief safe and reliable product size, as long as the proper placement, pipeline is a test pressure pass, safe operation, usually no maintenance, spare parts for decades without replacement.

Universal groove clamp connection can be used to connect seamless steel tubes, galvanized steel tubes, welded steel tubes, stainless steel tubes, copper tubes and other metal tubes.

The connected pipeline is a flexible system, which can absorb the length displacement of the pipe due to temperature change and allow the pipe to have a certain deviation Angle.
