新型输水管道-承插式涂塑钢管 Socket type steel pipe
目前城市供水管网大都采用球墨铸铁管道，具有安装方便、使用寿命长、维护技术成熟等优点。
涂塑钢管具有安全可靠、使用寿命长、无泄漏、内壁光滑、输送阻力小、不易结垢、水质好等优点。
我公司大胆创新，将两者的优点融合，在保留涂塑钢管优点的基础上，继承了球墨铸铁管柔性承插接口，并将两者的安装连接尺寸相统一。采用相同的T型胶圈，实现两种管材的相互安装连接，并且所有的管件按GB/T13295标准配制联系人：王经理15022027216。
At present, most of the city water supply pipe network is used in ductile iron pipe, which has the advantages of convenient installation, long service life and mature technology.
Steel plastic composite pipe has the advantages of safe and reliable, and the use of the advantages of long service life, no leakage, smooth inner wall, conveying resistance, not easy to scale, good water quality.
I company bold innovation, the integration of the advantages of both, while retaining the advantages of steel plastic composite pipe on the basis, inherited the spheroidal graphite cast pipe flexible socket interface, and the two mounting connection dimension of unity. Using the same Ttype rubber ring, are mutually connected to realize two kinds of pipes, fittings and all according to GB/T13295 standard.
