Laboratory Volatile Crude Oil Vapor Pressure Apparatus with Reid Method

Reid Method Vapor Pressure Test Apparatus
Model: BLDT

       Reid Vapor Pressure Test Bomb is conforming to ASTM D323-08 and GB/T 8017 <Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method)>. 
       This Test Bomb is designed for above standard methods which cover procedures for the determination of vapor pressure of gasoline, volatile crude oil, and other volatile liquid petroleum products.

Reid Vapor Pressure Apparatus, Consisting of two chambers, a vapor chamber (upper section) and a liquid chamber (lower section), shall conform to the following requirements:

Vapor Chamber:
       The upper section or chamber, shall be a cylindrical vessel having the inside dimensions of 51 mm in diameter and 254 mm in length, with the inner surfaces of the ends slightly sloped to provide complete drainage from either end when held in a vertical position. On one end of the vapor chamber, a suitable gauge coupling with an internal diameter of not less than 4.7 mm ( 3/16 in.) shall be provided to receive the 6.35 mm ( 1/4 in.) gauge connection. In the other end of the vapor chamber, an opening approximately 12.7 mm ( 1/2 in.) in diameter shall be provided for coupling with the liquid chamber. Care shall be taken that the connections to the openings do not prevent the chamber from draining completely.

Liquid Chamber-One Opening:
       The lower section or liquid chamber, shall be a cylindrical vessel of the same inside diameter as the vapor chamber and of
such a volume that the ratio of the volume of the vapor chamber to the volume of the liquid chamber shall be between 3.8 and 4.2. In one end of the liquid chamber an opening ofapproximately 12.7 mm ( 1/2 in.) in diameter shall be provided for coupling with the vapor chamber. The inner surface ofthe coupling end shall be sloped to provide complete drainage when inverted. The other end of the chamber shall be completely closed. (Warning-To maintain the correct volume ratio between the vapor chamber and the liquid chamber,paired chambers shall not be interchanged without recalibration to ascertain that the volume ratio is within the required limits.)

Liquid Chamber-Two Openings:
       For sampling from closed vessels, the liquid section of liquid chamber, shall be essentially the same as the liquid chamber described in Liquid Chamber-One Opening, except that a 6.35 mm (0.25 in.) valve shall be attached near the bottom of the liquid chamber and a 12.7 mm (0.5 in.) straight-through, full-opening valve shall be introduced in the coupling between the chambers. The volume of the liquid chamber, including only the capacity enclosed by the valves, shall fulfill the volume ratio requirements as set forth in Liquid Chamber-One Opening.

Thread of Gauge Connection: M20*1.5; 1/4 NPT F

Thread of Valves: M14*1.5; 1/4NPT M
