PVC pipes, commonly known as polyvinyl chloride pipes, are the most prevalent pipes used in plumbing today. They are strong and resistant to tearing or cracking when exposed to water pressure. Copper and plastic pipes have a few key distinctions. They are more environmentally friendly than pipes made of most other materials since they are sustainable and reusable. Most consumers are unaware that there are numerous types of PVC pipes since plumbers refer to them all as “plastic pipes.” Even so, they appear in a variety of forms and sizes, and people make them in a variety of ways.

Types of PVC Pipes
PVC-U stands for unplasticised PVC, which means the PVC compound has not been treated with a plasticiser. Rigid PVC is another name for unplasticized PVC. PVC-U is the most widely used PVC type for pipes and fittings in drinking water, soil and waste transportation, sewage and subsurface drainage, and industrial uses.
PVC-U pipes and fittings provide numerous advantages. They are a safe option for transporting drinking water, as well as being light, easy to handle, and cost-effective. High mechanical performance, long durability (at least 100 years for subterranean pipes), chemical resistance, and UV resistance are all technical features. PVC-U pipes are also environmentally friendly, as they are 100% recyclable.
Chlorinated PVC is abbreviated as C-PVC. C-PVC pipes and fittings share many of the benefits of PVC-U. Both are suitable to use with drinking water and have good corrosion resistance, durability, and impact resistance. C-PVC pipes and fittings, on the other hand, can resist a broader range of temperatures than standard PVC-U due to their greater chlorine concentration. As a result, C-PVC is a common material for water piping systems in both residential and commercial construction. PVC-U is substantially less ductile than C-PVC. C-PVC pipes and fittings are 100% recyclable.
Molecularly Oriented PVC
The addition of suitable modifying chemicals to PVC results in this family of thermoplastic alloys. The modifying chemicals improve the material’s fracture toughness and ductility by improving toughness, impact characteristics, and resistance to crack propagation. Because of the increased toughness, modified PVC pipes can be made with a thinner wall, resulting in material savings and improved hydraulic capabilities. When PVC is alloyed with modifying polymers, it becomes more resistant to cracking. As a result, the impact of stress concentrators like scrapes is reduced.
High Impact PVC
The newest variety of PVC pipes is high impact PVC, sometimes known as PVC-Hi. They’re made by mixing various chemicals into PVC-U to make it more impact resistant. While normal PVC has numerous benefits, it has restricted applications because of its instability. Professionals used PVC and polycarbonate to tackle this problem. This resulted in high-dimensional-stability alloy composition, especially when exposed to heat or pressure. Finally, a strong thermoplastic resin composition with great impact strength and thermal distortion resistance was produced.
Polycarbonate and a vinyl chloride resin alloy are frequently used in this formulation. Ethylene-vinyl acetate and butadiene-modified acrylic are two more materials combinations. Both variants turned out to be extremely inflexible. When regular PVC can’t tolerate the pressure or the severe temperatures, PVC-Hi is employed. It’s widely utilised for industrial liquids or in commercial sewage systems as a result of this. It’s also a good alternative for joining two pipes because they won’t be damaged during the cutting.
