Drilling Diverter


Suministramos desviadores de perforación de alta calidad que se fabrican y prueban de acuerdo con el estándar API / ISO.
● Body and upper housing are connected by a claw chuck.
● Compact structure realizes high bearing capacity.
● Easy to assemble and disassemble and convenient for wellsite operation.
● Use lip seal rings in dynamic seal section to realize self-sealing, reduce abrasion of sealing parts and make sealing more reliable.
● Use high quality packing element and sealing parts. Use tapered type packing element, which is made of NBR. It has massive storage volume and excellent sealing function.
● Use observation hole to check the life span of the packing element.
