Slotted Pipe Supplier

The slotted pipe is a pipe with slots or openings cut into the pipe wall. These openings allow fluid (mainly water) to flow while preventing larger particles from entering the pipe system. This type of pipe achieves a balance between fluid (mainly water) transmission and impurity filtration through precisely designed gaps. It is widely used in highway drainage, airport runways, urban rainwater management, and industrial fluid transportation, demonstrating the engineering value of efficient drainage and anti-clogging.

As an industry-leading solution supplier, UNIASEN offers a full range of carbon steel slotted pipes, using API 5CT standard H40/J55/L80/N80/C90/T95/P110 grade oil casing materials, processed by CNC laser cutting technology to ensure that the verticality error of the slot edge is less than 0.1°. We support customized straight or trapezoidal slots with slot widths ranging from 0.012 inches to 0.25 inches, and provide multiple layouts such as staggered slotted liners, group slotted liners, and straight slot liners to meet the needs of different scenarios.

Different slot layouts for slotted pipes

Different slot layouts for slotted pipes UNIASEN offers three different slot layouts for slotted pipes: straight slot liner, staggered slot liner, and grouped slot liner. These designs directly affect the permeability, filtration efficiency, and structural strength of the pipe. The following are the three slot layout types and their applications:

Straight Slots

The slots are evenly distributed in a straight line along the pipe axis, usually in a single row or multiple rows in parallel. Suitable for applications that require uniform flow, such as groundwater extraction or simple drainage systems.

Staggered Slots

The slots are arranged in a staggered manner, with adjacent slots staggered in the axial direction, forming a chessboard-like distribution pattern. Especially suitable for oil fields with uneven sand grain sizes, it can effectively prevent sand grain clogging.

Grouped Slots

The slots are distributed in groups, each group contains multiple dense slots, and there is a large gap between groups, forming a segmented slot. Suitable for applications that require centralized drainage, such as wastewater treatment or road drainage systems.

Slotted Pipe Advantages

Easy and efficient installation

The carbon steel slotted pipe features a modular quick-install design for tool-free splicing. The flexible interface with ±5° angle deviation to adapt to terrain, and enables 100-meter pipe laying in one day, boosting efficiency by 70%.

Quality assurance system

Each UNIASEN pipe has a built-in electronic tag, which can be traced throughout the quality process, and we provide free technical guidance.

High strength and corrosion resistance

The carbon steel slotted pipe has an anti-rust coating to extend the service life in the open air. At the same time, the compressive strength is as high as that of heavy-duty vehicles without deformation, and it is resistant to low and high temperatures, and suitable for various harsh environments.

High cost-effectiveness

Compared with materials such as stainless steel or aluminum, carbon steel slotted pipes have lower costs while ensuring performance, which is suitable for large-scale engineering projects and provides economical and efficient solutions.
