Featuring an innovative, 6-sample test design

The durable, dependable design of Ayalytical Instruments’ LPG corrosion vessel guarantees full compliance with ASTM D1838, IP 411, and ISO 6251. This apparatus is ideal for detecting the presence of components in liquefied petroleum gases that can be corrosive to copper. Copper corrosion limits are vital in preventing difficulties with deterioration of the copper and copper-alloy fittings and connections commonly used in many types of transportation and storage equipment. The test is performed by emerging one polished copper test strip in each of the LPG-filled test cylinders at a specified temperature for approximately one hour, then comparing the test strips to copper strip corrosion standards.

Designed with safety and efficiency in mind, this solidly-constructed, 90-liter polished stainless steel LPG corrosion vessel is equipped with a constant digital PID micro-processor for the ultimate in temperature regulation, as well as an overtemperature alarm for operator safety. The liquid indicator, visible from the outside of the instrument, allows for easy fill without overflow while the internal light indicator alerts to low liquid levels. The stainless steel electric heating component on this LPG testing equipment allows for the quick warming of liquids while the cooling coil provides improved control near ambient temperatures. The digital thermoregulator PID temperature control maintains ±0.1ºC and the motorized agitator delivers consistent mechanized stirring for the most stable of testing conditions. This LPG corrosion vessel is supported by an external frame with an epoxy acid-proof coating, ensuring an extended working lifetime.

This reliable, easy-to- operate LPG corrosion Bath allows for the emersion of 6 pressurized cylinders for the simultaneous testing of multiple samples; covers working temperatures ranging from ambient to 90ºC (194 ºF) to maintain LPGs in liquid state; and features an insulated double wall for the maximum in heat conservation during testing.
