Tianze - PVC-U Sealing Joint

PVC-U drain pipe is a series of drain pipe products with mature technology, which has been widely used at home and abroad. The products have the advantages of long life and corrosion resistance unparalleled in cast iron pipes; In the construction, it has the characteristics of light weight, easy handling, installation and connection, and is widely used in civil building drainage and sewage, chemical drainage and sewage, rainwater drainage and other fields. PVC-U drainage pipe and fittings meet the standard requirements of GB/T5836.1-2018 and GB/T5836.2-2018.

The product has three forms of straight pipe, expanded pipe and expanded pipe, and can use a variety of pipe connection methods. In addition, the company has developed pressure drainage pipes for rainwater drainage and beautiful square rain downspouts for rainwater drainage design and engineering of different buildings; A series of drainage pipes, such as spiral silencer, hollow spiral silencer and hollow wall silencer, have been developed to reduce drainage noise.

• The surface hardness and tensile strength of the pipe are excellent, and the pipeline safety factor is high.
• Good aging resistance, normal service life can reach more than 50 years.
• The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, and is suitable for industrial sewage discharge and transportation.
• The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to plug, and the maintenance workload is less.
• The material has high oxygen index and self-extinguishing performance.
• The linear expansion coefficient of the pipeline is small, which is 0.07mm/m.?, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and the frost resistance is better than that of cast iron drainage pipes.
• The connection of pipe and pipe fittings can be bonded, the construction method is simple, the operation is convenient, and the installation efficiency is high.
• Industrial and civil building indoor and outdoor drainage pipeline projects, continuous discharge of domestic sewage temperature is not greater than 40?, instant discharge of sewage temperature is not greater than 80?; And industrial wastewater that does not corrode the pipe can be used.

Pipe socket connection should be strictly operated in accordance with the following procedures:

1. Wipe the pipe socket and pipe fitting socket clean before bonding.
2. Measure the depth of the socket and mark the pipe port.
3. Paint the adhesive, first paint the socket, and then paint the socket, the coating is uniform and appropriate.
4. Align the direction, insert it into the marking part at one time, and rotate 1/4 turn.
5. Wipe the adhesive remaining in the socket.
6. Stand the bonded pipe until the interface is cured.

The safe use of adhesives should comply with the following provisions:

1. Adhesives and cleaning agents should be used on demand, and non-operators should not use them.
2. There should be no open flame at the bonding point, and the ventilation should be good.
3. It should not be constructed below -10?, and the adhesive point should not be baked with fire.
4. Construction personnel should be equipped with gloves. If the adhesive strays into the eyes, immediately flush with plenty of water, send to the hospital for treatment.

Saw pipe and groove:

The length of the saw pipe is determined layer by layer according to the measured measurements and the dimensions of each connected pipe fitting. Pipe sawing tools should be selected fine tooth saw, cutter and pipe cutting machine and other tools. The fracture should be flat and there should be no deformation in the section. The part of the socket to be glued can be filed into a 15°-30° groove with a medium board file. The groove length is generally not less than 3mm, and the groove thickness should be 1/3-1/2 of the pipe wall thickness. After the groove is finished, the debris should be removed.

Socket protection:

After connecting the socket, scrub the extruded adhesive with cotton yarn or dry cloth dipped in a little detergent such as acetone. Static until the interface is cured according to the performance of the adhesive and climatic conditions. Winter construction curing time should be properly extended.
