铸石复合管Cast basalt lined steel pipe

铸石复合管是由内衬铸石管、外套钢管和两者之间的水泥沙浆充填层构成，它集铸石管的耐磨损、耐腐蚀性能，钢管的韧性和水泥砂浆的固结性于一体。***的提高了产品对各种复杂工况的适应能力。同时使用水泥砂浆作为充填料，可使钢管内表面处于碱性介质中，钢管表面产生纯化膜，可防止锈蚀。既耐磨损、耐腐蚀、又抗较高压力、且运输方便。

Cast basalt lined steel pipe is made with lined cast basalt pipes, coat steel pipe and the cement mortar filling between the two layers, it sets the wear resistance and corrosion resistance of cast stone pipe, the toughness of the steel pipe and the consolidation of the cement mortar in one. Greatly improve the product&＃39;s ability of adapting various complicated working condition. At the same time using cement mortar as filling material, can make the pipe inner surface in alkaline medium, so that the surface of the steel pipe will produce a purified film to prevent corrosion. Cast basalt lined steel pipe is not only resistant to wear and corrosion, against high pressure, but also convenient and safe to transport.

铸石复合管分为直管、弯管、三通（四通）管、变径管等。

Cast basalt pipe can be divided into straight pipe, elbow, three(four)-way  pipe and variable diameter pipe, etc.

铸石复合弯管通径系列与铸石复合直管相同，其转弯半径和中心角按用户要求制作。

The nominal diameter series of cast basalt lined steel elbow pipe is the same as the cast basalt lined steel straight pipe , the turning radius and central Angle can be made according to the requirements of customers.

铸石复合管外套钢管技术参数按管路系统运行压力确定。

The technical parameters of the coat steel of cast basalt lined steel pipe according to the operating pressure of the pipeline system to determine.

铸石复合管是由内衬铸石管旬套钢管和内、外套管之间的水泥沙浆充填层构成。它集铸石管、钢管性能于一体，即耐腐蚀又抗高压，且安装运输方便，铸石管分直管、弯管、三通等。
