PTT Cooking Gas Business

Building on the success in the LPG market, PTT formulated a business strategy for LPG in 2024 under the concept ‘LPG for All,’ incorporating the 5Cs:Customer: Engaging in business collaborations with dealers, Consumer: Accessing consumers directly, Community: Enhancing the quality of life for communities and society, Country: Creating a society focused on safety and sustainability, Collaboration: Conducting business through collaboration among all parties to foster business growth, while taking care of stakeholders from all aspects

To ensure that OR’s customers are safe while using the product, OR focuses on providing product knowledge training to suppliers and customers. and performing emergency drill plans for the customers at the LPG filling plant and LPG service stations regularly, as well as increasing the safety standards of cooking gas cylinders, which are made of steel that is thicker than the required standard in order to ensure the cylinders withstands pressure very well. The material has been certified by the Thai Industrial Standards Institute (TISI). Every cylinder must pass the standard 6 step quality control and safety measures before being delivered to consumers as follows:

Inspect the condition of the cylinder to determine whether it meets the safety standards. There must be a TIS mark stamped on the cooking gas cylinder. If a cooking gas cylinder is found to not meet the standards, it will be sorted for maintenance or destruction.
Clean the cylinders that have already passed the standard LPG cylinder condition inspection.
While filling the gas cylinder, the gas weight must be controlled according to the standard of size of the cylinder.
In the weighing process, if the weight is lacking or exceeds the specified standard, the cylinder is taken back to the filling station to be refilled and re-weighed. This ensures that every cylinder meets the LPG content standard.
Inspect the cylinder for leaks by testing the flue gas cylinder, valves, and valve threads. If a leak is found, the cylinder will be sorted out immediately.
Inspect the valves and gold seals. The inspection of the tightness of the seals is the final step before delivering the cylinder to the shop for further delivery to the consumer.

Cooking gas cylinders that have reached the age of 5 years from the month/year of the last test will be put to the hydrostatic test process to re-test for leaks. Cylinders that have reached the age of 10 years will be put to the expansion test process to determine the expansion rate of the gas cylinder at the specified pressure according to the industrial product standard regarding the use and maintenance of liquefied petroleum gas cylinders (TIS 151). The valves of the cylinder must also undergo a safety testing process. Valves that are less than 10 years old will be tested for leakage and safety relief. Valves that are damaged or older than 10 years will be destroyed to ensure that consumers use the safest cooking gas cylinders.

OR has integrated the safety innovation “Check Lock Valve System” according to TIS 915-2562 standard regarding valves for liquefied petroleum gas cylinders, with a tongue design for the fuel gas cylinder to prevent gas leakage and fires during transportation and consumer use.
