   Greene Tweed宣布推出WR 650,是其耐磨(WR)组合最新的热塑性复合材料.
  
  WR 650增强了三维碳纤维结构,在最大限度地提高设备可靠性的同时,比领先的PFA基材料提供了更好的性能。
  WR 650具有优良的干燥性能、良好的耐化学性和工作温度。
  高达260°C(500°F)。其较高的纤维含量提供了一个更硬的材料在广泛的工作温度。
  WR 650具有重要的竞争优势,包括:
  2.5倍于领先的PFA基材料在干运行条件下的PV限值
  在不稳定条件下保持生产,特别是在干式运行期间,增加MTBR(平均修理间隔时间)。
  轴向热膨胀系数(CTE)是前导热膨胀系数的四倍。
  PFA基材料
  一种适用于所有应用的单一、可靠的材料-高温、腐蚀
  快速的产品交付确保了泵故障时物料的可用性。
  几家炼油厂、化工厂、发电厂、管道和水处理厂选择Greene Twide公司的复合材料,因为它们能够在最恶劣的环境中承受最具挑战性的应用。

  Greene Tweed announces the introduction of WR 650, the newest thermoplastic composite in its wear-resistant (WR) portfolio.
  A thermoplastic composite with dry run traits
  WR 650 is reinforced with a three-dimensional carbon-fiber architecture, offering enhanced performance over the leading PFA-based material, while maximizing equipment reliability.
  WR 650 offers superior dry run capability, good chemical resistance, and an operating temperature
  up to 260°C (500°F). Its higher fiber content provides a harder material over a wide range of operating temperatures.
  WR 650 offers significant competitive advantages, including:
  2.5 times higher PV limit in dry run conditions over the leading PFA-based material
  Maintains production during upset conditions, particularly during dry runs, increasing MTBR (mean time between repair)
  A CTE (coefficient of thermal expansion) four times lower in the axial direction than the leading
  PFA-based material
  A single, reliable material that covers all applications – high temperature, corrosion
  Rapid product delivery ensures material availability during pump breakdowns
  Several refineries, chemical plants, power generation plants, pipelines, and water treatment plants choose Greene Tweed’s composites for their ability to withstand the most challenging applications in the harshest environments.
