随着国标弯头技术的发展，目前为室内供暖系统能提供各种不同用途的塑料管材。由于国标冲压弯头管材具有内壁光滑、热媒流动阻力小，耐酸碱、使用寿命长，安装方便等优点。近几年来被供暖系统中广泛的应用，国标冲压弯头做为新一代的采暖专用管材正逐步成为采暖市场的主流产品。现代管材特点：有LTHS的优点；能承受强烈冲击的优点；光滑的表面；半永久性的使用寿命(中韩认证使用寿命100年)；在高温、低温下突出的柔软性;热熔接以及可再生利用;用做自来水管道时可满足卫生的要求:环保性.国标冲压弯头采用特殊的分子设计和合成工艺生产的聚乙烯管。
With the development of national standard elbow technology, various kinds of plastic pipes for different purposes can be provided for indoor heating system at present. Because of its smooth inner wall, low resistance to heat medium flow, acid and alkali resistance, long service life and convenient installation, the national standard stamping elbow pipe has many advantages. In recent years, it has been widely baojijil.89ix.com namimumen.89ix.comdipingc.89ix.com fengguanl.89ix.comshuiguan.89ix.comzhicaoz.89ix.comused in heating system. As a new generation of heating pipe, stamping elbow is gradually becoming the mainstream product in heating market. Modern pipe features: LTHS advantages; strong impact resistance; smooth surface; semi-permanent service life (100 years of certificated service life in China and Korea); outstanding softness at high temperature and low temperature; hot fusion and renewable use; when used as tap water pipeline, it can meet the sanitary requirements: environmental protection. The national standard stamping elbow adopts special molecular design and synthetic process production. Polyethylene pipe.
