Project Background
A natural gas transmission project in a region of Thailand required the laying of a natural gas pipeline of several tens of kilometres long to connect the gas fields to the city gas network. The project placed high demands on the safety, reliability and service life of the pipeline.
After several rounds ‘discussion by technicians and engineers from both parties via online meetings,finally the co-extruded pipe was decided to be used for this application.
PUHUI Solution
PUHUI’s advanced HDPE double co-extruded pipeline technology and extensive project experience provided the perfect solution for this project.PUHUI HDPE double co-extruded pipelines are designed for natural gas transmission and offer the following outstanding advantages:
Superior Safety: PUHUI HDPE double co-extruded pipelines are designed for natural gas transmission.
Excellent permeation resistance: The double co-extruded structure effectively prevents gas permeation and ensures the safe transmission of natural gas, eliminating the risk of leakage.
Outstanding stress crack resistance: Special material formulation and processing technology enables the pipe to withstand high pressure and complex stress, preventing cracking and ensuring long-term safe operation.
Reliable connection: Adopting hot-melt connection technology to realise seamless connection of the pipe, ensuring the strength of the connection is the same as that of the pipe body, and eliminating the potential risk of leakage.
Long service life.
Excellent corrosion resistance: HDPE material itself has excellent chemical corrosion resistance, and the double-layer co-extruded structure further enhances the corrosion resistance of the pipe, effectively resisting soil acids and alkalis and microbial erosion, ensuring the long-term stable operation of the pipe in harsh environments.
Good anti-aging performance: HDPE material has excellent anti-UV aging performance, the service life can be more than 50 years, far more than the traditional metal pipeline, greatly reducing the life cycle cost of the project.
Efficient construction: HDPE is easy to install.
Lightweight and easy to install: HDPE pipes are lightweight, easy to transport and install, and can be connected by hot-melt connection technology, which makes the construction fast and efficient, effectively shortening the project duration.
Adaptable to complex terrain: The pipeline has good flexibility and can adapt to complex terrain, reducing the use of elbows and lowering construction difficulties and costs.
Project results acheived:
PUHUI HDPE double layer co-extruded pipeline was successfully applied in the project and passed the acceptance. The project manager spoke highly of PUHUI’s product quality and service level, saying that PUHUI’s HDPE double co-extruded pipeline perfectly fits the needs of natural gas transmission and provides a safe and reliable guarantee for natural gas supply in a region of Thailand.
