PVC pipes’ benefits
1. Transportability: UPVC material has a specific gravity that is only one-tenth that of cast iron, making it less expensive to ship and install.
2. UPVC has high acid and alkali resistance, with the exception of strong acids and alkalis close to the saturation point or strong oxidizing agents at maximum concentration.
3. Non-conductive: Because UPVC material is non-conductive and does not corrode when exposed to current or electrolysis, no additional processing is necessary.
4. There is no concern about fire protection because it cannot burn or promote combustion.
5. Installation is simple and inexpensive thanks to the use of PVC adhesive, which has proven to be dependable and safe, simple to use, and inexpensive. Cutting and connecting are also quite straightforward.
6. Excellent weather resistance and resistance to bacterial and fungal corrosion make anything durable.
7. Small resistance and high flow rate: the smooth inner wall minimizes fluid fluidity loss, prevents debris from sticking to the smooth pipe wall, and makes maintenance relatively easy and inexpensive.

Plastic is not PVC.
PVC is a multipurpose plastic that may be used for a variety of things, including common furnishings and building sites.
In the past, PVC was the most widely used plastic in the world and had a variety of uses. It is widely used in construction materials, industrial goods, everyday necessities, floor leather, floor tiles, synthetic leather, pipes, wires, and cables, packaging films, bottles, fibers, foaming materials, and sealing materials, among other things.

The World Health Organization’s International Agency for Research on Cancer first compiled a list of carcinogens on October 27, 2017, and polyvinyl chloride was one of the three types of carcinogens on that list.
Amorphous polymer with traces of crystalline structure, polyvinyl chloride is a polymer that substitutes one chlorine atom for one hydrogen atom in polyethylene. This document is organized as follows: n [-CH2-CHCl] The majority of the VCM monomers are joined in a head-to-tail configuration to form the linear polymer known as PVC. All of the carbon atoms are joined together by bonds and are organized in a zigzag pattern. Every carbon atom has an sp3 hybrid.

The PVC molecular chain has a brief syndiotactic regular structure. The syndiotacticity rises as the polymerization temperature falls. There are unstable structures including head-to-head structure, branched chain, double bond, allyl chloride, and tertiary chlorine in the polyvinyl chloride macromolecular structure, which results in drawbacks like low thermal deformation resistance and aging resistance. Such flaws can be fixed after appearing to be cross-linked.

PVC connection method:
1. A specific glue is used to join PVC pipe fittings; the adhesive must be shook before use.
2. The socket component and PVC pipe need to be cleaned. The less space there is between the sockets, the smoother the surface of the joints should be. Then, equally brush the glue into each socket and twice brush the glue on the exterior of each socket. 40 seconds after drying, put Put the glue away and pay attention to whether the drying time should be increased or decreased in accordance with the weather.
3. The pipeline must be backfilled 24 hours after the dry connection, the pipeline must be installed in the ditch, and getting wet is strictly prohibited. When backfilling, save the joints, fill the area surrounding the pipe with sand, and backfill extensively.
4. To link the PVC pipe to the steel pipe, clean the junction of the bonded steel pipe, heat it to soften the PVC pipe (without burning it), and then insert the PVC pipe into the steel pipe to cool. The result will be better if hoops made of steel pipe are incorporated.
PVC pipes can be connected in one of four ways:
1. If the pipeline has sustained extensive damage, the complete pipeline should be replaced. A double-port connector can be utilized to do this.
2. The solvent approach can be used to stop solvent glue leaks. At this point, the main pipe’s water is drained, creating a negative pipe pressure before the glue is injected into the hole at the leak site. The glue will be pulled into the pores as a result of the pipeline’s negative pressure, stopping the leak.
3. The major target of the sleeve repair bonding procedure is the leakage of the casing through tiny cracks and holes. The same caliber pipe is now chosen for longitudinal cutting and ranges in length from 15 to 500 px. The inner surface of the casing and the outer surface of the repaired pipe are connected at the joints in accordance with the procedure used. After applying glue, the surface is roughened, and it is then firmly fastened to the source of the leak.
4. To create a resin solution using an epoxy resin curing agent, use the glass fiber method. It is evenly woven on the surface of the pipeline or the leaky junction after being soaked in the resin solution with a glass fiber cloth, and after curing, it becomes FRP.
