滴灌管是一种用塑料管道将水（液体肥料或农药等）通过灌溉毛管上的圆柱式压力补偿滴头送到作物根部进行局部灌溉的塑料制品。
Drip irrigation tube is a plastic product which applies the plastic tube to deliver water (liquid fertilizer or pesticide) via cylindrical pressure compensation drippers on the tubular billet to the root of crops for partial irrigation. 
滴灌管是滴灌灌溉系统中的重要灌溉产品,它是按照作物需水要求，通过低压管网与安装在毛管上的灌水器（滴灌管滴头），将水和作物需要的养分一滴一滴，均匀而又缓慢地滴入作物根部的土壤中，避免了水肥输送过程中的渗漏、挥发与浪费，可以最大程度节省水肥，降低成本。
Drip irrigation tube is an important irrigation product in the irrigation system. It can slowly and evenly drop water and nutrients needed by crops into the soil around the root of crops via the low-pressure pipe and irrigation device (dripper of the drip irrigation tube) installed on the tubular billet according to the demand of crops for water, avoiding leakage, volatilization and waste during delivery of water and fertilizer, significantly saving water and fertilizer and reducing the cost. 
内镶圆柱式滴灌管生产采用聚乙烯材料制作，内部添加黑色母等，管体为黑色，具有质轻抗裂耐用的特点。与滴灌带相比，管壁较厚，管材质量极高。
The embedded-style cylindrical drip irrigation tube is made of PE with black color base added inside. So, the tube is black, light, anti-crack and durable. Compared with the drip irrigation hose, the wall of the embedded-style cylindrical drip irrigation tube is thicker and has extremely high quality. 
目前常用的内镶圆柱式滴灌管为Φ16型滴灌管。滴灌管规格按壁厚可分为0.6毫米、0.8毫米、1.0毫米三类。正常工作压力为0.08MPa-0.1MPa。单个滴头间距固定，均为300毫米，滴头出水量均匀稳定，单个滴头流量为2-3.5L/h，最大铺设距离不应超过80米。
Currently, the commonly used embedded-style cylindrical drip irrigation tube is Φ16 drip irrigation tube. The drip irrigation tube can be classified into three types based on the wall thickness: 0.6mm, 0.8mm and 1.0mm. The normal working pressure is 0.08MPa-0.1MPa. The dripper space is fixed (300mm). Water can be dropped evenly and stably. The flow of each dripper is 2-3.5L/h. The maximum laying distance shall be no longer than 80m. 
因为内镶圆柱式滴灌管产品质量较高，壁厚较大。因此高强度的滴灌管使用年限较滴灌带而言要长很多。因此，滴灌管在使用时一定要注意做好过滤工作，避免堵塞问题的发生。在首部必须配套安装过滤器，常见的主要有离心式过滤器、网式过滤器、叠片过滤器及砂石过滤器等。
Since the embedded-style cylindrical drip irrigation tube has high quality and thick wall, the service life of high-strength drip irrigation tube is much longer than that of the drip irrigation hose. Thus, filter shall be conducted properly when using the drip irrigation tube, avoiding blocking. An applicable filter shall be installed in the front of the tube. Commonly used filters include centrifugal filter, screen filter, laminated filter and sand filter.
