Drainage pipe means a system of pipes and appurtenances for the collection and discharge of sewage.The system of pipes and drains and their appurtenances that collect and discharge wastewater and stormwater.It includes trunk pipes.Branch pipes and pipes leading to treatment plants, whether constructed in the street or anywhere else where they serve as drainage, shall be counted as drainage pipes.

Leaking Sewer Pipe

.
Countermeasures: i. PVC pipe leaking solution: 1. glue seal note: use glass glue or PVC glue plugging after a layer of wax. 2. rubber seal: interface leakage on the interface of the unscrewing, in the middle of the rubber gasket and then tighten; middle leakage on the leak wrapped rubber skin, with shrinkage iron hoops tight. 3. direct replacement: the best method is to change the pipe, so as to solve the fundamental problem.II.Cast iron sewer pipe leak solution: crack leak is generally due to the pipe with a long time, aging appears, if the temporary patch can be made up with cement on the outside, and then wrapped in a layer of adhesive paper, and so the cement condensed and then remove the adhesive paper on the line.Interface leaks, interface leaks lighter available cement mortar package or coated, the heavy need to remove the original filler, re-play asbestos cement mouth.

Sewer pipe price

Sewer pipe prices are generally around $30 a meter.

Sewer pipe specification

A flexible connection is preferred for the jointing day of round pipes.When the conditions are limited, the pipeline should be appropriately configured along the foundation soil conditions flexible connection interface.For pipes laid in seismic zones, the requirements of the corresponding seismic design codes shall be implemented.For cast-in-place reinforced concrete rectangular pipeline, mixed structure rectangular pipeline, deformation joints shall be set along the line.Deformation joints should be through the full section, the distance between joints should not exceed 25m; joints should be set at the waterproof measures (such as water stop.Sealing materials).For prestressed concrete round pipes, a longitudinal prestressing stress shall be applied, the value of which shall not be less than 20% of the corresponding effective precompressive stress in the annulus.For factory-made reinforced concrete or prestressed concrete round pipes, the net protective layer thickness of the reinforcement shall not be less than 12mm when the wall thickness is 8~10mm; and not less than 20mm when the wall thickness is greater than 100mm.

Sewer pipe installation

First, when the sewage pipe enters the construction site, the relevant staff should carefully and carefully check each sewage pipe.Once found that there are cracks and defects, or there is not in line with the standard, can not meet the requirements, can not be used.Second.In the process of sewage pipe installation, for the pipe connection prefabricated, must help the relevant bearing mouth to remove the existence of oil and rust.Third.Remember to use oil sisal filler for filling.And for cement joints the mix must be kept moderate and try not to choose to fill it at once.Fourth.When carrying out the sewer pipe prefabricated, must keep the sewer pipe flat and straight, so that the interface can choose wet straw bag dressing cover regeneration.Not only that, the sewer pipe should also be placed horizontally among the safe lot, must avoid stomping and other situations.

Size of drainage pipe

Nominal outer diameter (mm): φ25, φ32, φ40, φ50, φ63, φ75, φ90, φ110, φ125, φ140, φ160, φ180, φ200, φ225, φ250, φ280, φ315, φ355, φ400, φ450, φ500, φ560, φ630, φ720, etc. Special sizes are available.Special sizes can be made to order.
