 | Material - 700 Class Pintle Chain links are cast of high grade Duramal. Duramal is a heat treated malleable iron having greater strength and superior resistance to wear and abrasion. A copper alloy is standard in Webster Malleable and Duramal® Iron for greater resistance to corrosion. Pins are heat treated. |
| Assembly - Cottered construction is furnished unless riveted construction is requested. |
| Interchangeability - Please refer to our INTERCHANGEABILITY CHARTS for corresponding sizes and numbers. |
| Application - These chains are adapted to loads ranging from
normal to heavy and for speeds up to 300 FPM. They are extensively used in water and
waste water treatment installations. Because of the closed joint construction, these
chains can be applied where semi-abrasive or moderately abrasive materials are to be
handled. Maximum chain speed depends upon the size of sprockets. For Conveyor
