Yesterday the Minmetals Nonferrous and Ganzhou tungsten co published guidance price is different, Minmetals flat 65 degree black tungsten concentrate bid to 110000 yuan / ton, Ganzhou tungsten co down 3000 to 107000 yuan / ton, the two price is still higher than the actual price, in this price spot market sale does not ship. It is understood, now a 65 degree black tungsten concentrate 105000 yuan / ton are difficult to sell, 65 degree white tungsten concentrate even now 103000 yuan / ton low price.

The two institutions offer the differences, continued weak downstream demand, businesses at present mainly wait-and-see, late funds tense shippers shipping intention or slightly increased, the short term price of the tungsten vulnerable, there is still risk small fell.

Hardide Coatings has supplied its Hardide T nano-structured tungsten carbide coating for a new range of trunnion-mounted ball valves for the UK energy sector.

The ‘Phase’ range includes numerous variations of soft and metal seated side entry ball valves, used for the safe isolation of pipeline production and process equipment. These valves are often used in erosive operating environments, so the new valve required a durable protective tungsten carbide coating. The Phase range comes in both metal to metal and soft seated options which posed additional considerations.Metal to metal seated valves often suffer wear by erosion when there is particulate in the process fluid. Most ball valves are soft seated, but wear can also cause scratches and resultant leakage.

Heap & Partners selected Hardide-T for use in the range, particularly in the smaller diameter valves, for several reasons, including the inherent hardness of Hardide-T, at 1100 to 1600 Hv with a typical tungsten carbide coating thickness of 50 microns. Hardide-T is produced in a gas-phase CVD (chemical vapour deposition) process.

“The Hardide coating achieved excellent results, meeting all the required leakage rates and delivering consistent results on various substrates,” said Peter Burnett, business development manager at Heap & Partners. “We also chose to partner with Hardide Coatings as we worked with the team previously on a project in the nuclear sector to tackle a corrosion issue and carry out re-engineering of valves.”

Corrosion resistance

Heap & Partners has now utilised Hardide-T on many ball valve applications for both oil and gas and nuclear clients. There have been no wear issues since employing the tungsten carbide coating and it has provided protection from erosion. In some cases the Hardide coating has also improved the corrosion resistance of the base material.

Minmetals announced yesterday August guidance prices flat with July, but Ganzhou tungsten co downregulated, tungsten, mentality also weakened, waste tungsten market wait-and-see atmosphere thickening, merchants offer to steady, the market price is still more resources. Ammonium paratungstate prices fell, tungsten concentrate not yet noticeable drop.

Waste tungsten market mainstream remains stable. At present, the waste tungsten bit not including tax price of mainstream is still concentrated in the 188-190 yuan /kg, domestic waste tungsten blade 169-171 yuan /kg, imports of scrap tungsten blade 179-181 yuan /kg, waste tungsten grinding material 30-40 traders purchase price concentrated in the 1.45-1.5 yuan / degrees, 50-70 degrees concentrated in the 1.55-1.7 yuan / degrees, 70 degrees or more concentrated in the 1.7-1.75 yuan / degree, expected short-term waste tungsten market are weakening running stability of.

Tungsten market: tungsten, rich atmosphere, businessmen wait tomorrow upcoming guide price. Tungsten smelting factories on-demand procurement of raw materials. Weak demand, only a small amount of the transaction, the transaction has tungsten atmosphere more deserted, at home and abroad for demand weakness, but compared to other products in China this summer for price decline is very small, the current waste tungsten prices relatively stable, shippers pricing power is insufficient, the market low price resources still more mainstream, expected short-term market stabilization.
