Type classification of pe drainage pipe

Time of issue : 2017-12-15 00:00:00

Drainage pipes are mainly responsible for drainage of rainwater, sewage, irrigation and drainage of farmland. Drainage pipes are divided into concrete pipes (CP) and reinforced concrete pipes (RCP). Drainage pipe specifications include pipe inner diameter DO (100mm-3000mm), length LO (30mm-200mm), pressure index, grade Ⅰ, grade Ⅱ and grade Ⅲ. The caliber is divided into: flat mouth, tongue and socket, socket, double socket, steel socket. Production of reinforced concrete drainage pipe equipment: mixing system, pipe mold (flat mouth, tongue and socket, double socket, steel socket), forming equipment (centrifuge, suspension roller, vertical axial extrusion molding machine, vertical Radial extrusion molding machine, core mold vibration hydraulic molding machine, vertical radial extrusion molding machine, core mold vibration hydraulic molding machine, vibration molding device), feeder, steel plate skeleton roll welding machine, hydraulic press, external pressure Machine waiting. The drainage pipe is a new type of permeable and drainage plastic pipe with corrugated appearance formed by adding other additives to high density polyethylene (HDPE). The permeable corrugated pipe is perforated in the groove, and the outer circumference of the pipe is covered with acupuncture geotextile. Processed. According to the type of bellows, it can be divided into single-wall water-permeable bellows and double-wall water-permeable bellows. Because the pipe hole of this product is in the wave trough and is elongated, it effectively overcomes the drawbacks of flat round hole products that are easy to be blocked and affect the drainage effect. According to different drainage requirements, the size of the pipe hole can be 10mm×1mm-30mm ×3mm, and can be evenly distributed in the range of 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc., widely used in roads, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields and partial moisture content High-induced slope protection and other drainage fields, as well as underground irrigation and drainage systems for agriculture and horticulture. Together with soft permeable pipes and plastic blind ditch, it has become the three main products in civil engineering construction (water seepage and drainage) in my country. Depending on the drainage pressure, the municipal drainage network can choose double-arm corrugated pipes and straight wall pipes. Straight-wall pipes have strong pressure bearing capacity and can be used as special pipes for large drainage and sewage pipe networks.

Noise reduction measures for PVC drainage pipes

Time of issue : 2017-09-29 00:00:00

Jiangsu Belden Plastic Industry Development Co., Ltd. is a professional manufacturer of PVC drainage pipes. 　　 PVC drainage pipe noise reduction measures. 　　 People think that the noise of PVC drainage pipe is louder, which is also one of the obstacles in the promotion of this product. After testing, the noise of PVC drainage pipes at the bottom is 2 to 3 decibels larger than that of cast iron drainage pipes, which does not exceed the national standard for noise in daily life. But why do users have greater feedback on this issue? The first reason is that people are There is a process of adapting to the new environment. Building a building will amplify the sound due to the echo effect of the empty house; the second is the inadequate technical measures adopted in the design. For this reason, I believe that the first thing to do is to keep the drainage riser away from the room and living room when designing; pay special attention to the technical requirements at the junction of the riser and the bottom drainage pipe during construction. This elbow should use two 45° elbows. Connect and set up buttresses at the bottom of the riser to prevent settlement. I think that the plastic pipe buttress must be located at the lower end of the riser axis, and wrap the entire elbow to make the water flow in the riser fall to the real place, so that the impact sound is also reduced. This type of buttress not only plays a role in preventing settlement , Also has the effect of eliminating noise, of course, it is bigger than the buttress at the bottom of the cast iron drainage pipe. In order to reduce the noise of the bottom layer, some felt or rubber cushions can be put into the inner side of the holder of the bottom riser pipe to tighten properly, so as not to hinder the expansion of the riser pipe.

FAQ

What is the difference between PVC water supply pipe and PVC drainage pipe

Time of issue : 2018-03-22 00:00:00

1. Different purposes: one for water supply and one for drainage. PVC water supply pipes are mainly used for: a. Indoor water supply and reclaimed water systems for civil and industrial buildings; b. Buried water supply systems for residential quarters and factories; c. Urban water supply pipeline systems; d. Water treatment plant water treatment pipeline systems; e. Marine aquaculture; f. Garden irrigation, well sinking and other industrial pipes. PVC drainage pipes are mainly used for building drainage and domestic sewage drainage. 2. Different specifications: PVC water supply pipes have more specifications and models, and PVC drainage pipes have relatively fewer specifications and models, because the drainage system itself does not require too many specifications. Even with the same model (outer diameter), the wall thickness of the water supply pipe and the drain pipe are often different, because the water supply pipe requires pressure, and the drain pipe usually does not need to consider the pressure. 3. The price is different: This will not be explained in detail, and the specific price can be consulted by each manufacturer.

Ways to reduce the noise of PVC drainage pipes

Time of issue : 2018-03-22 00:00:00

While adding stabilizers to improve the chemical stability and strength of pvc pipes, the sound insulation performance of the plastic itself has been greatly weakened. Therefore, in the current situation of reliable mechanical performance of pvc drainage pipes, how to solve the problem of sound insulation and noise reduction has become a top priority. The author believes that we can start with the noise source and adopt the following improvement measures to improve its sound insulation performance: ①It is made into double-wall hollow sound-proof PVC drainage pipe The special equipment for PVC pipe extrusion is modified, an intermediate mold is added between the inner and outer jacket, and the outer mold is modified to increase the intermediate distance to form a hollow cavity between the two walls, so that the plasticity of PVC will not be changed. But it can increase the damping of the pipe along the flow direction, thereby increasing Strong sound insulation effect. Using single-wall double-material PVC pipe On the basis of the original single-wall PVC pipe, a secondary formula is carried out, that is, the porous sound-absorbing material formed by plastic foaming technology is used to increase the wall thickness to achieve the purpose of increasing the damping along the outer wall direction, so as to obtain a good sound insulation effect. A set of equipment needs to be added, thus increasing the manufacturing cost. Muffled PVC drainage pipe The PVC pipe is made into a muffled drainage pipe with spiral fins attached to the inner wall. At this time, its outer wall is still a PVC hard plastic pipe (to ensure the required strength of the drainage pipe), but a certain width of flexible and strong soft is attached to the inner wall Plastic spiral belt, which unloads part of the impact pressure of the water flow onto the spiral belt, thereby buffering the pipe wall.
