Bridge slotted water well screens

Bridge slotted water well screens, a type of well screen with vertical slots that are formed by protruding “bridges” that are pushed outward from the well casing. The slots of this kind of screen  are punched precisely in a flat sheet which then is rolled into a pipe.The sand and gravel can’t easily block the slot because of the special bridge style design,and Bridge Slot Screens has great mechanical strength and water entering capacity.Meanwhile, Bridge Slot Screens use steel punching technology and is rolled in many ways, so they are light, cheap and easily operating.

Johnson screen,water well screen

Johnson screen,water well screen are manufactured by wrapping a shaped wire around an internal array of longitudinal rods. The wire and rod, generally made from carbon or stainless steel are joined by resistance welding. Screen sections are usually twenty feet long. The ‘V’ or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous and consistent slot opening. Most continuous wire wrap screens are manufactured from stainless steel in order to avoid problems associated with sand pumping that may result from accelerated corrosion of carbon steel screens. steel well screen Manufacturing Process:. specifications of Johnson screen,water well screen                                         […]

Pipe base screen

Pipe base screen is manufactured from two components: the base pipe and the slip-on screen. The base pipe will be perforated with a series of holes drilled to a pre-determined quantity and pattern, to carefully balance flow-capacity at each end for both down-hole handling.The holes are then debarred and the joint cleaned, inspected and treated to give the base pipe a long shelf life.Our slip-on screens are manufactured to very exact diameter, length gauge and strength tolerances. specifications of Pipe base screen Pipe base screen Screen API Pipe ID(mm) OD(mm) SLOT(mm) Normal size(inch) OD(mm) 63 73 0.10-3 2-3/8” 60.3 74 85 0.10-3 2-7/8” 73 92 102 0.10-3 3-1/2” 88.9 103 127 0.10-3 4” 101.6 116 130 0.10-3 […]

Pre-Packed well Screen 

The Pre-Packed well Screen  has been integrated with the latest Wire Wrap technology to provide outstanding durability and performance. This Pre-Packed well Screen  assembly consists of an inner perforated base pipe, jacketed by two Wire Wrapped Screens. The annulus between the two jackets ispacked with a high quality filter media. The gauge of the inner and outer jackets is determined by the size and type of filter media. The gauge should be equal to half of the smallest diameter of the filter media. The filter media is chosen based on the formation sands that are to be controlled. The standard filter media used is high quality gravel pack silica sand, fully curable resin coated reseived gravel pack sand or ceramic beads are also available. Industrial vibrating machines are used in conjunction with careful loading of the filter media to ensure proper compaction and even distribution. High intensity light is used during the inspection process of each Pre-Packed Screen. Each assembly is 100% void free. Pre-Packed Screens are an economical alternative that may be used to complete vertical or horizontal wells when a conventional gravel pack is not feasible.
