6 Slotted Pipe
Slotted Liner
- Slotted Drain is a unique pipe which removes sheet flow without multiple grades or water channeling devices. The pipe is cut along a longitudinal axis, and a trapezoidal or straight-sided grate with reinforcing spacer plates is welded to form a 1 3/4 -inch-wide slot opening.

- This 6 Inch Perforated Drainage Pipe can be used around your home or farm to assist in controlling your subsurface water drainage. This corrugated pipe is single wall and constructed of HDPE. HDPE drain pipe is abrasion and chemical resistant. This pipe is 6 inches in diameter and 100 feet long.
The actual outside diameter of 6' nominal size PVC pipe is 6.625 in. This industry standard size pipe fits with 6' nominal size PVC fittings and valves. PVC pipe is used in everything from drainage to plumbing and craft projects. PVC is a relatively lightweight and cost effect piping material that is easy to install with PVC solvent cement. EZflow French Drain 15 in. Slotted Pipe is available to buy in increments of 10 Details EZflow gravel-free french drains provide exceptional performance for a variety of applications including retaining walls, landscape drains, foundation and footing perimeter drains and sports fields.
Slotted liners are made from tubulars by saw-cutting slot configurations. Slot widths are often referred to in terms of gauge. Slot or screen gauge is simply the width of the opening in inches multiplied by 1000. For instance, a 12-gauge screen has openings of 0.012 in.
The slots can be straight or keystone shaped, as illustrated in following picture. The keystone slot is narrower on the outside surface of the pipe than on the inside. Slots formed in this way have an inverted ”V” cross-sectional area and are less prone to plugging because any particle passing through the slot at the outside diameter of the pipe will continue to flow through, rather than lodging within the slot.
Application
The slotted liners are usually less costly. They have smaller inflow areas and experience higher pressure drops during production. Slotted liners also plug more readily than screens. They are used where well productivity is small and economics can not support the use of screen.
Perforated Pipe
The perforated Liner or Pre-perforated Casing is manufactured with a 44ft 88 spindle drill press. Joints with sizes up to 20” Length range 3 and grades up to 13CR110 are perforated in one handling.
Our standard spiral and staggered perforation patterns use3/8” and 1/2” diameter holes, to create the required open area.
Upon request, custom sizes hold can be drilled in any number and any pattern.
Pipe is deburred internal and external as well as drift tested according to API standards. Every hole is visually inspected and cleaned of burr material.
The size, grade and weight of the base-pipe are according to API casing or tubing specification.
6 Slotted Pipe Clamp
Wire Wrapped Screen
The wire-wrapped screen consists of perforated pipe, outer jacket, end ring and centralizer. Key-stone or house shape wires are simultaneously wrapped and welded to form uniform slots.
The jacket is then placed over perforated pipe and welded to each end. The wire-wrapped screen’s strength, high quality and precise slot control make it an excellent choice for deep, vertical wells as well as horizontal wells.
ADVANTAGES
Key-stone shaped slot pattern, low risk to plugging, easy to clean
Superior resistant to corrosion and long lifespan in applications
Optimized design for perforation, all welded structure, high mechanical strength which is competitive with casing of the same size.
Minimum slot opening: 0.1mm, which can satisfy the most of well-completion requirements.
High flow area
The technical is mature, good adaptability.
APPLICATION
Gravel-packing in cased-hole completions of vertical wells, directional wells, horizontal wells, multi-lateral wells and open-hole completions.
Bridge Slot Screen
Screen features bridge-like slot, which creates a gap between the well casing and the packed gravel.
Bridge slots are spaced in rows or in staggered state.
6 Slotted Drain Pipe
Bridge slotted screens are first punched in a flat sheet, which is completely CNC operated. The slot widths are precise and can change as practical requirements. Then the flat sheet is subsequently rolled and welded into a tube.
Bridge slot screen has extensive applications, including water and oil wells, development of geothermal development and mineral water.
ADVANTAGES
Bridge slot has outstanding anti-plugging performance for its unique bridge construction.
Bridge construction also enhances the mechanical strength against twisting, compressive and tensile forces.
Diverse external coatings are available to extend the operational lives of watering wells.
Bridge slot screen is lightweight and quire affordable compared with other conventional well screens.
Slot widths can be customized to satisfy customers’ specific requirements.
Multilaysers Premium Screen
Multilayers Premium Screen performance is derived from two characteristics, the filter media and secondly the overall construction of the screen. Consists of base pipe, layered filtration jacket and outer shroud.
