Tungsten carbide welding bars are commonly used in the oil and gas industry for various applications. These bars are made from a combination of tungsten and carbon, which results in a very hard and wear-resistant material.

Raw material prices rise sharply According to Sun Chemical Co., a subsidiary of Dainippon Ink Chemical Industry Co., Ltd. (DIC), since the beginning of the year, the price of rosin resin has risen by 75%, which is an increase of 300% compared with the same period of last year. Rosin resin can be used to produce printing inks and pigment brighteners. Due to the limited supply of stimuli, the current price of this material has risen sharply and will rise further in the future.
Rosin resins are mainly divided into three categories: gum rosin, tall oil rosin, and hydrocarbon rosin. Among them, gum rosin is mainly from gum tree, which is mainly produced in Brazil and China. Tallow oil rosin is obtained by fractionation of tall oil. Hydrocarbon rosin resin includes aliphatic resin and aromatic resin. The raw materials of these resins are derived from nacre. Oil cracker.
Gary Reed, head of North American operations at Arizona Chemical Corporation, a large US rosin resin manufacturer, pointed out that the strong growth in demand for rosin resin led to a significant increase in its price. The strong growth in China's domestic demand for gum rosin and the increase in labor costs have stimulated the price of China gum rosin to soar from US$600-900/tonne to US$3,200/tonne in the past 18 to 24 months. Hydrocarbon rosin resin production capacity is also very tight, because the unplanned shutdown of some ethylene plants earlier this year had an impact on the market.
Sun Chemical stated that the prices of other raw materials for printing inks are also rising sharply. The price of pigments has risen significantly this year and is expected to further increase by 5% next year.
Raising the price to cope with the increase in costs Due to the shortage of raw materials, especially the shortage of rosin resin and most of the pigments, Sun Chemical raised the price of cold-set printing inks in Europe in October this year. Among them, the price of cold solid color inks increased by 0.4 euros/kg, and that of cold solid black inks increased by 0.3 euros/kg. At the end of September this year, the company had increased the packaging ink price in the US market by 4% to 14%.
Also under the pressure of rising raw material prices, Flint Ink recently announced that it will raise the price of printing inks in Europe from January 1, 2011. Among them, the price of thermosetting ink was raised by 0.45 euro/kg, the price of cold-set ink was increased by 0.35 euro/kg, and the price of printed gravure ink increased by 0.40 euro/kg. Floyd Ink ink company vice president Broman said that the increase in ink prices can only partially compensate for the increase in raw material costs this year.
The supply shortage will continue. Ed Prut, Chief Purchasing Officer of Sun Chemicals, pointed out that the company's upward adjustment of product prices is still insufficient to make up for the rising costs. Faced with the challenge of tight supply of raw materials, the company's life in 2010 was not very good. For 2011, Pruitt expects that the tight supply of raw materials will ease, but it will still exist.
A senior vice president of raw materials procurement for Flint Ink Company stated that the shortage of raw materials may force ink manufacturers to change product formulations.
1. Hardfacing: Tungsten carbide welding bars are used for hardfacing applications, where a wear-resistant layer is applied to drilling tools, valves, pumps, and other equipment exposed to abrasive environments. This helps to extend the lifespan of the components and reduce maintenance costs.
2. Drill bits: Tungsten carbide welding bars are used to manufacture drill bits for oil and gas exploration. The hard and durable nature of tungsten carbide makes it ideal for drilling through tough rock formations.
3. Wear plates and liners: Tungsten carbide welding bars are used to create wear plates and liners for equipment used in oil and gas production. These plates and liners protect the underlying metal surfaces from abrasion and corrosion, ensuring the longevity of the equipment.
4. Valve seats and seals: Tungsten carbide welding bars are used to manufacture valve seats and seals for oil and gas valves. The high hardness and wear resistance of tungsten carbide ensure reliable sealing and prevent leakage in critical applications.
5. Downhole tools: Tungsten carbide welding bars are used in the manufacturing of downhole tools such as stabilizers, reamers, and drill collars. These tools are subjected to high pressures, temperatures, and abrasive conditions, and tungsten carbide helps to enhance their durability and performance.
Overall, tungsten carbide welding bars play a crucial role in the oil and gas industry by providing wear resistance, hardness, and durability to various components and equipment.
Global printing ink producers clamor for
Printing ink manufacturers all over the country have complained recently that the supply of raw materials is too tight. This is because raw material producers have drastically reduced their production capacity during the economic downturn and weak market demand, but they cannot meet market demand when demand improves. The tight supply of raw materials led to a significant increase in the cost of ink producers. In the past few months, they have been forced to raise prices several times to keep up with the increase in raw material prices.
