Tianjin Aokai Oil Tools Co., Ltd. products

The continuous-slot well screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry. Aokai Continuous-Slot Well Screen is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods.

Aokai Continuous-Slot Well Screen is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Slot opening for continuous-slot screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size.

Slot opening for continuous-slot screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings.Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the screen surface. The V-shaped openings designed to be nonclogging, are narrowest at the outer face and widen inwardly; they allow.

Perforated casing is manufacturing with API casing, joints with size up to diameter 20"and length R3. Every joints perforated is deburred internal and external. Upon request,we can drill standard or customized hole size in any number and nay patter.

Sorts: API casing. Length: ≤15m (each). Outside Diameter: 50~200mm. Slot Width:(0.10~4)mm ±0.03mm;. Slot Number: as per customer’s requirement. Slot Shapes: straight in line pattern, staggered pattern, spiral pattern;. Slot space: as per customer’s . requirement. Slotted casings with apertures of 0.20~6mm are wide used in sands prevention of oil and wells.

It is suitable for filtering tank, water treatment equipment, padding under the filtering . medium and even layout of top water. According to your requirements, we can process and manufacture various shapes of sieve plates.

Hub Laterals can be designed for disc head vessels enabling the system to collect completely to the bottom of the vessel. Header Laterals design are also available for flat bottom vessel distributor or collector applications. Systems can be designed to accommodate side, center, top or bottom inlet piping. Integral backwash systems can be designed for any hub and header lateral for fast effective and efficient cleaning. Connections of the laterals can be flanged or threaded. All systems are designed for effective liquid or solid retention in a wide range of applications including exchangers, clay and sand filtration applications, carbon towers and power plants with water systems.

Water strainers(nozzles) are manufactured in accordance to customer flow requirements in almost any alloy. They can be designed for filtration or treatment systems to permit more effective use of the treatment media. Because of their non-clogging design strainer are effective in a wide range of water treatment and other industrial applications. Common applications include under drain media retention elements or flow distributors in demineralizers and water softeners in pressure and gravity sand filters. Strainers can also be used as collectors at the bottom of the vessels by installing a number of strainers uniformly across a tray plate. The combination of high open area and a non-plugging slot design makes this nozzle/collector application popular. Our nozzles are most commonly made with 304 or 316L stainless steel.

The company specialized in produce all kinds of Oil Pipe Connectors, strictly in accordance with American Petroleum Institute Standard API. The main products are 2-3/8″, 2-7/8″, 3-1/2″, 4-1/2″ EU & NU oil pipe connectors, 5-1/2″, 7″,9-5/8″casing coupling connectors, various spec oil pipe sections, adjustable joints and various machinery products. At home, the products are sold to major oil fields and oil pipe manufacturers.

Centralizers are used to center the screen within the borehole. They should be of sufficient strength and surface area to provide support, yet not impede the installation of gravel. These are conflicting requirements, and some compromise is required. A simple guide, which has proven effective, is manufactured from 5/16 x 2 inch steel, 30 inches long, bent to provide the proper centering distance. This distance or bend is usually the theoretical borehole radius minus one inch. The guides are attached to the screen by welding. Three or four guides are placed equidistantly around the screen at 40 foot intervals.
