JIS K-6774 Polyethylene Pipes for the Supply of Gaseous Fuels

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of JIS K-6774 testing. JIS K-6774 is a Japanese Industry Standard that specifies the requirements for high-density polyethylene (HDPE) pipes used for the supply of gaseous fuels such as natural gas, town gas and liquefied petroleum gas (LPG). The standard defines specifications, materials, dimensions and performance requirements for these pipes.

Some of the key requirements specified in JIS K-6774 include:

• Material: Pipes should be made of high density polyethylene (HDPE) meeting JIS K-6741-1 requirements. The material must also comply with other requirements regarding mechanical properties, chemical resistance and durability.
• Dimensions: Pipes should be available in various sizes ranging from 20mm to 630mm in diameter. The standard specifies the minimum wall thickness, outside diameter, and tolerance limits for each dimension.
• Performance requirements: Pipes must meet specific performance requirements regarding compressive strength, impact strength, and resistance to rapid crack propagation.
• Joining methods: The standard defines various joining methods such as forehead fusion, electrofusion and mechanical joining. Each joining method must meet certain requirements regarding strength, durability and tightness.

In general, JIS K-6774 ensures that polyethylene pipes used for the supply of gaseous fuels are of high quality and can withstand the rigors of use in a gas distribution network.
