DIE FORMED GRAPHITE RING

- Graphite Die Formed Rings are produced from high purity homogenous flexible graphite with no binders or fillers and have outstanding chemical resistance.

- Our moulded rings are manufactured on site using our extensive range of tooling or to customers specific requirements, they can be supplied individually or in sets as a square section, chamfered and/or split in matching halves, rings can also be supplied with metal end caps for high pressure anti extrusion applications.

- Moulded/ Die Formed Rings have the ability to provide a leak-free seal for high performance valve applications, with their excellent chemical resistance and the ability to withstand most media in the oil and gas industry.

- Working alongside our German Supplier SGL we are able to offer a wide range of graphite grades including oxidation resistance, High purity graphite and corrosion inhibited grades to suit a wide range of applications.

- Graphite Ring là tên tiếng của Gioăng chì nén, ở Việt nam nó được gọi theo nhiều cái tên khác nhau như: Graphite đúc, graphite ring, graphite tết cối, vòng graphite đúc, O-Ring Graphite...
