中国预应力钢筒砼管行业前景广阔但竞争激烈


发布时间:

2015-09-25

核心提示:目前,预应力钢筒砼管(pccp)管材分两个类型:内衬式预应力钢筒混凝土管(pccpl)、埋置式预应力钢筒混凝土管(pccpe)。内衬式和埋置式的区别,前者系指在钢筒内壁成型砼层后,在钢筒外表面上缠绕环向预应力钢丝,并作水泥砂桨保护层而制成的管子;后者系指在钢筒内、外侧成型砼层后,在管芯检外表面上缠绕环向预应力钢丝,并作水泥砂桨保护层而制成的管子。

目前,预应力钢筒砼管(pccp)管材分两个类型:内衬式预应力钢筒混凝土管(pccpl)、埋置式预应力钢筒混凝土管(pccpe)。内衬式和埋置式的区别,前者系指在钢筒内壁成型砼层后,在钢筒外表面上缠绕环向预应力钢丝,并作水泥砂桨保护层而制成的管子;后者系指在钢筒内、外侧成型砼层后,在管芯检外表面上缠绕环向预应力钢丝,并作水泥砂桨保护层而制成的管子。

行业分析师指出:上世纪80年代末我国建成第一条pccp生产线,到2005年4月国家发改委等五部委颁布《中国节水技术政策大纲》明确提出大口径管材(dn>1200mm)优先考虑pccp之前,pccp行业处于市场开发阶段。从1988年到2005年的18年间,全国各种口径的pccp产量仅约2500公里,平均每年产量仅约140公里。大纲颁布后,随着相关工程业主对pccp相对其他管材比较优势的认识,pccp需求量开始快速增长。2006年我国各种口径pccp产量达到600公里,pccp行业步入快速发展的初期阶段。2008年全国各种口径pccp产量达到了1578千米。2012年我国预应力钢筒砼管(pccp)管材行业产量达到了2378千米,截止2013年,全国各种口径pccp产量达到了2647千米。

到2015年我国城市人口将增至5.5亿,人均用水量为173m3 /年,总缺水量约为460亿m3;目前农业用水的供需缺口约为600亿m3;加之目前的输水管网严重老化,每年需要更新大量的管道,以配合城市原有输(排)水管网的改造工程。

为解决上述问题,经保守计算,需要最近10年共新增26285公里pccp标准管,平均每年新增pccp标准管约2629公里。目前pccp行业面临较为严重的供小于求,产能不足的格局。

pccp行业在中国处于快速增长的起步阶段,而仅从跟踪目前已经立项的水利、输水项目工程来看, pccp有巨大的增长空间 。

从市场方面来看,pccp目前毛利率水平较高,行业前景广阔,但行业竞争将趋于激烈,除行业内企业扩大生产规模外,原分属建材、市政、水利行业的传统水泥制管企业也开始转型或新增设备进入pccp行业,此外,一些行业外企业,如大型建设企业集团也开始试图涉足pccp市场。
