We, Zhenglin Building Materials, are the largest integrated supplier of plastic inspection wells in East China. Let’s talk about the classification of plastic inspection wells. Plastic inspection wells can be basically divided into two types according to their structures: wellbore type and pipe type. A wellbore inspection well refers to a well with a complete cylindrical structure from top to bottom, and the wellbore diameter is larger than the diameter of the pipe; a pipe-type inspection well uses a part of the pipe as the bottom of the inspection well, and the wellbore diameter is equal to or smaller than the pipe diameter. . Plastic inspection wells are divided by product type: rainwater plastic inspection wells, sewage plastic inspection wells, saddle joints, composite manhole covers, reducing joints, variable angle joints, heat shrink sleeves, rubber rings, HDPE hollow winding pipes, PVC hollow shafts, HDPE Plastic manhole shaft.

The product models are divided into 315, 450, 630, and 700 as wellbore numbers, 315*200, 315*250, 450*300, 450*400, and 630*500 models are complete!

Product specifications are divided into starting wells, straight wells, three-way wells, 90-degree elbow wells, 45-degree elbow wells, and four-way wells, with various specifications! Zhenglin Building Materials plastic inspection wells are made of HDPE and are disposable injection molded plastic inspection wells.

1. Product models: 315 series, 450 series, 630 series, 700 series.

2. Product specifications: starting well, straight well, three-way well, four-way well, 90-degree elbow well.

1. The inspection well connected to the PE pipeline is called the inner diameter series plastic inspection well.

2. The inspection well connected to the PVC pipe is called the outer diameter series plastic inspection well.

IV. Main specifications for connecting outdoor drainage pipes:

PE pipes: 200, 225, 300, 400, 500, 600

PVC pipes: 200, 250 , 315, 400, 500

5. Plastic inspection wells are divided into categories: flow channel wells and sedimentation wells. Rainwater wells need sedimentation, with a sedimentation chamber underneath, and sewage wells have flow channels.

6. Plastic inspection wells are divided into injection molding and rotational molding according to the process.

7. Plastic inspection wells are divided into: PVC HDPE and PP according to material.
