（绕焊不锈钢筛管、地热井滤水管、防砂筛管）

楔形丝筛管由符合API标准的基管和高精度的楔形丝滤水管组成。

产品特点：

1、承受压力能力强，适用于比较恶劣的使用环境。

2、管径较细，减轻了钻井的施工难度。

3、标准筛管的开口率为21%,也可根据客户要求进行调整。

4、外层筛管缝隙均匀，误差小，能有效起到防砂作用。

5、连续的V型结构使得水流渗入速度减小，减轻了管体与设备所受压力。

6、基管材质为API标准的J55、K55、N80等，外层筛管为不锈钢304，也可按照客户要求使用其他材质。

适用环境：千米深井，石油井，地热井，施工条件恶劣的地层。

The Pipe-based screen is a perfect combination of a high perbance profile wire screen and a strong internal pipe. It utilizes a very accurate V-shaped wire welded onto supporting rods to b a jacket that is assembled onto the perforated pipe – making them ideally suited to deep wells.

The very close slot control tolerances prevent sand migration.

Most importantly, the V-shaped continuous slot opening ensures better flow perbances and is specially designed for very severe conditions.

As standard, 304 stainless steel is used in the manufacture of the jacket, and J55 or K55 for the pipe base. The standard external screen open area is 21%, although other percentage open areas are available.
