Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
According to foreign media reports on June 28, Turkmenistan’s President Gurbangure Berdy Mohammedov said in Ashkhabad on June 27th that Turkmenistan plans to begin exporting natural gas to China in 2009.
Berdy Muhammedov said that the diversification of transport routes for exporting energy to the world market has always been a priority issue for the Turkmen government. Turkmenistan has an estimated 24.6 trillion cubic meters of natural gas reserves.
Turkmenistan - China's natural gas pipeline construction began in August 2007 in the Bagtyyarlyk Special Economic Zone on the left bank of the Amu Darya in Turkmenistan. The natural gas pipeline will be developed by the state-owned oil giant China National Petroleum Corporation.
According to an agreement signed in April 2006, China plans to purchase 30 billion cubic meters of natural gas from Turkmenistan every year within 30 years.
