The origin of HDPE pipe

TVT2002_2025 — Sun, 15 Jan 2023 17:01:46 +0000

For more than 70 years HDPE (High Density Polyethylene) has been discovered accidentally during an experiment in the 1950s. Since then, HDPE has completely revolutionized human life. With outstanding properties of HDPE such as strong and durable, Resistant to heat and chemical, HDPE is used as a raw materials in the production of consumer products such as water bottles, shampoo bottles, toys, water pipes and many more.

HDPE (High Density Polyethylene) is produced from a Catalytic polymerization via catalyst. The process creates a chain of polymers under constant pressure and temperature.

The evolution of HDPE pipes started in 1959 with the first HDPE pipes manufactured according to class PE 50, with an internal pressure rating of 5 MPa (50 bar) used as sewer pipes, agricultural pipes and mine pipes. Later, the HDPE pipe industry improved HDPE polymers for pipes having higher quality and withstand higher pressure. The second generation HDPE pipes were produced with class PE 63 with an internal pressure rating of 6.3 MPa (63 bar), and PE 80 with an internal pressure rating of 8 MPa (80 bar) respectively. They are mainly used for water supply, drainage, agricultural pipes, chemical pipes, industrial pipes, etc.

In 1995, the production process of raw materials used in the production of HDPE water pipes was further developed. By using the Bimodal production technology, it allows the pipe to withstand more pressure while reducing the wall thickness. The new material is class PE100 with an internal pressure rating of 10 MPa (100 bar) and is the class used until today.

HDPE pipes are replacing ductile iron and concrete pipes due to their superior properties such as strong and durable, Resistant to pressure, heat and chemicals. HDPE pipes manufactured in Thailand must be manufactured according to the Thai Industrial Standards TIS 982-2556

TIS. or “Thai Industrial Standards” are standard procedures required for a product or service designed for the benefit of consumers organized by the Thai Industrial Standards Institute or TISI.

The Thai Industrial Standards Institute or TISI. requires all food, electrical goods, vehicles, construction materials and others to comply with the Thai Industrial Standards.

Thai Industrial Standards for rigid uPVC for drinking water classified in the mandatory standards. The standard was firstly introduced in 1972 as TIS. 17-2514. Later, two more revisions of TIS. 17-2523 and TIS. 17-2532 were implemented in the year 1980 and 1989 respectively. TIS. 17-2532 has been implemented for over 30 years until the latest revision of TIS. 17-2561 was introduced in 2019 and has been implemented since then until present.

Let us understand what the Thai Industrial Standard TIS 17-2561 is about and how is it different from TIS 17-2532

1) Rigid uPVC pipe for drinking water produced according to TIS. 17-2561 is classified with 5 pressure ratings of Class 5, Class 7, Class 8.5, Class 10.5 and Class 13.5 unlike TIS. 17-2532 which is classified with 3 pressure ratings of class 5, Class 8.5 and Class 13.5.

2) Rigid uPVC pipe for drinking water produced according to TIS. 17-2561 requires more testing on effect on water compared with TIS. 17-2532 where the smell, color and taste must not be changed and no hazardous substance and heavy metals found. The contaminate of lead cannot exceed 1,000 mg/kg and cadmium cannot exceed 100 mg/kg from the surface of the pipe. The extracted solvents from the water cannot exceed with mercury 0.001 g/cm3, lead 0.01 g/cm3, arsenic 0.01 g/cm3, Selenium 0.01 g/cm3, Chromium 0.05 g/cm3, Cyanide 0.07 g/cm3, Cadmium 0.003 g/cm3, Barium 0.7 g/cm3 and the total dissolved substance cannot exceed 70 g/cm3

3) Rigid uPVC pipe for drinking water produced according to TIS. 17-2561 have added new density parameter compared with TIS. 17-2532 where the density of PVC is 1,350-1,460 kg/m3 tested at ± 23 ℃

Effect of Ultraviolet Radiation (UV) on PVC Pipes

TVT2002_2025 — Sun, 11 Dec 2022 17:01:58 +0000

Ultraviolet Radiation or UV rays affect the PVC pipe when exposed to sunlight for a long period of time. The UV rays may cause fading in color and also the performance of the pvc pipe to drop.

Polyvinylchloride or PVC has the chemical formula (C2H3Cl)n. According to the quality testing standards, it has been proven that PVC pipe has a lifespan of more than 50 years even though it is exposed to UV rays for a long period of time. As the external layer is affected, the internal layer of the PVC pipe still helps to maintain its original properties and helps withstand the effect of Ultraviolet radiation.

Thai Vinytech (2002) Co., Ltd has high manufacturing standards with latest technologies. Our Research and Development team have developed a special formula to help improve the UV stability on uPVC pipes by adding a set of stabilizers in the manufacturing process ensuring that Thai Vinytech (2002) uPVC pipes has excellent properties to withstand Ultraviolet Radiation compared with other manufacturers in the market.

How long can PVC pipe last?

TVT2002_2025 — Sun, 13 Nov 2022 17:01:22 +0000

The lifespan of a PVC pipe depends on the use and quality of the pipes. High-quality pvc pipes that are manufactured according to the TIS 17-2561 standards are durable and strong. If the consumer chooses high-quality PVC pipe products and has them installed correctly by certified engineers, we can expect that the PVC pipe can be used for over 50 years.

The durability of PVC pipes depends mainly on the chemical degradation of the polymers used as raw materials in the manufacturing process. Thai Vinytech (2002) manufactures its uPVC pipe by selecting high-quality 100% virgin raw materials and compounding them with stabilizers and antioxidants to ensure long-lasting use of the PVC pipes. PVC pipes are mostly installed inside the building or underground, as a result, they are not exposed to the Ultraviolet rays from sunlight, which can reduce the life cycle of a PVC pipe.

For general use inside the building or underground applications, we can expect the PVC pipe to be used for over 50 years. However, other factors such as wrong pressure calculations, chemical exposure, or improper installations may affect the lifespan of PVC pipes.
