Drilling Fluids The RIGCHINA low pressure/low temperature filter press design features a cell body to hold the mud sample, a pressure inlet, and a base cap with screen and filter paper. Suitable for field and laboratory use, these units have become the industry standard for low pressure/low temperature filtration testing. RIGCHINA also manufactures other types of filter press units and inventories a full line of replacement and consumable parts. Stainless steel cases are available for most of the units. When several tests must be run simultaneously, as in a laboratory environment, multi-units are available in either two, four, or six- cell designs. These multi-units come complete with manifolds and all necessary air hoses and bleed-off valves. The field portable units are supplied with various pressurization assemblies and manifolds and rely mainly on carbon dioxide bulbs and nitrogen gas to provide pressure. The American Petroleum Institute (API) recommends a standard 100 ± 1.0 psi (690 ± 6.9 kPa) cell pressure be applied within 30 seconds for a 30 minute test. When high pressure and high temperature filtration measurements are required, HTHP filter presses designed specifically for simulating down-hole conditions are recommended. Test temperatures for all models may exceed 200°F (93°C), provided a back-pressure receiver is used to collect the filtrate. The components of the RIGCHINA HTHP filter presses are fully interchangeable with those marketed by other manufacturers. Three different sizes are available to accommodate different requirements and preferences. All HTHP units may be ordered with 115 Volt or 220 Volt power requirements. A multi-unit laboratory model is available and may be custom designed to your specifications. A wide variety of accessories and replacement parts are also available. Filter Press API (LPLT) Model RCLF-1A Measuring filtration behavior and wall-cake building characteristics of a mud is essential to drilling fluid control and treatment. The characteristics of the filtrate, such as oil, water or emulsion content, are also fundamentally important. The types and quantities of solids in the fluid and their physical and chemical interactions affect these characteristics. Temperature and Rigchina Group Co.

pressure in turn affect the physical and chemical interactions. It is therefore necessary to run tests at both low-pressure/low-temperature and high-pressure/high-temperature. Each of these testing conditions requires different equipment and techniques. The most effective means of determining the filtration properties of drilling muds and cement slurries The Series RCLF-1A APT Low Pressure Low Temperature (LPLT) Filter Press consists of a mud reservoir mounted in a frame, a pressure source, a filtering medium, and a graduated cylinder for receiving and measuring filtrate. The basic unit has a...
