About this product:

better  'B' &' W' Annular BOPs  are  compact,  strong and simple construction with reliably  seal which  provide positive  pressure control for stripping drill into and out of hole. Ram type BOP is  simple and  compact  and is suited for land and platform applications. The ram in the BOP is pressure energized. The well pressure acts on the  ram to increase the sealing force  and maintain the seal even with loss of the closing pressure.  ‘B’ Bolted Cover Annular BOP (For small sizes or lower working pressure) 'W' Wedge Cover Annular BOP (For large sizes or higher working pressure)�� Available Working Pressures (PSI) Bore Sizes 7-1/16" (180mm) 9" (230mm) 11" (280mm) 13-5/8" (346mm) 16-3/4" (426mm) 18-3/4" (476mm) 20-3/4" (527mm) 21-1/4" (540mm) 10,000 √   √ √         5,000 √ √ √ √ √ √   √ 3,000 √ √ √ √       √ 2,000
