WR® 525
PEEK(聚醚醚酮)
Greene Tweed
产品描述
WR® 525 is a thermoplastic composite consisting of carbon fiber in a PEEK matrix. Because of its unique thermal expansion properties, WR® 525 is ideal for use as impeller wear rings, bushings and case wear rings.
WR® 525 allows the pump user to increase pump efficiency by running tighter wear ring clearances, while decreasing potential pump damage when pumps are cavitated or experience down-line bearing failures. WR® 525 is API 610 approved for (stationary/stationary and rotating) wear applications.
Features and Benefits
• Steel replacement
• Extremely lightweight
• Low coefficient of thermal expansion
• Excellent chemical resistance
• Nongalling/nonseizing properties
• Low coefficient of friction
• Impact resistance
• Thermal shock resistance
Availability
• For a length of 162 inches - 164 inches, the maximum outside diameter is 60 inches.
• For a length of 414 inches - 416 inches, the maximum outside diameter is 24 inches.
• Outside Diameter Capability: GT will currently build to an outside diameter of 60 inches, and can address larger diameters on demand.
• Wall Thickness: Wall thickness must be greater than 0.0055 inches. ID/ radial wall thickness ratio is recommended as 10:1. There is no maximum wall thickness limitation.
