What are the classifications of fire trench pipe fittings

The production and manufacture of ductile iron pipe fittings are constantly developing in line with market demand. Among them, the unique technical feature of grooved pipe fittings is that the structure of the inner wall of the pipeline will not be damaged when the connection is made. In addition, there are many characteristics, so here is not one by one. introduced. Next, let's take a look at what are the classifications of fire-fighting trench pipe fittings? In order to help us understand them.

Grooved fittings

1. Connectors:

Rigid joints, flexible joints, flexible joints, inner wire joints, outer wire joints, inner and outer wire joints, monofilament joints, double wire joints, threaded joints, pressure gauge joints, gas meter joints, pipe meter joints, card sleeve joints , Flared joints, welded joints, socket joints, etc. 2. Elbows

2. Three links:

Positive tees, reducing tees, oblique tees, Y tees, bottle tees, mechanical tees, saddle tees, grooved tees, butt welding tees, socket tees, card sleeve tees , Internal tees, special heating tees, internal and external tees, threaded tees, external tees, silencing tees, water tees, band-edge tees, forged tees, seamless tees, sanitary tees Pass

3. Four-way type:

Positive cross, oblique cross, mechanical cross, equal diameter cross, reducing cross, flat cross, three-dimensional cross, groove cross, butt welding cross, threaded cross, socket cross, seamless Four-way, sanitary four-way

4. Reducing pipes:

Concentric reducer, eccentric reducer, reducer grooved reducer, sanitary reducer, welded reducer, inner screw thread reducer, outer screw high pressure reducer, double bearing Reducer

5. Flanges:

Grooved flanges, flat flanges, flat welding flanges, butt welding flanges, high diameter flanges, blind cover flanges, neck flanges, socket welding flanges, sanitary flanges

6. Elbow category:

Groove type, elbow card sleeve type, elbow butt welding, elbow socket, elbow bendable, flexible rubber elbow, internal tooth elbow, external tooth elbow, internal and external tooth elbow, with edge elbow, Seated elbow, diameter elbow, seamless elbow, flange elbow, double bearing elbow, sanitary elbow, 45° elbow, 90° elbow, 180° elbow

7. Elbow category:

Elbow bridge, elbow pressure gauge, elbow sharp bend, elbow U-shaped, elbow S-shaped elbow

8. Pipe caps:

Cap hexagon, cap round tube, cap threaded cap, butt weld cap head, round head, oval head, cone head, no straight side head,

9. Pipe fittings:

Hexagonal Bu, Shen repair rod tube, card water separator tube seat

To sum up, the classification of fire-fighting groove pipe fittings in ductile iron pipe fittings is roughly joint type, three-way type, four-way type, reducer type, flange type, elbow type, elbow type, pipe cap type, pipe Accessories, etc. After reading the introduction of the above content, I think you have almost understood its classification. I hope the above information is helpful to you!
