产品结构确定后采用何种工艺进行生产是截止2013.6.19经济活动中至关重要的，
它直接关联了产品的生产成本和生产效率，同时又反过来对产品的结构设计、材料的选择提出工艺上的要求。内筋嵌入式衬塑钢管采用独特的机械拉拔复合工艺，通过对金属管的缩径压迫内层塑料管，使两种材料产生永久性合理过盈，加之焊管内表面独特设计的花纹内筋对塑料管外表面的嵌入作用，以及塑料管复合前的物理和化学改性，使得内筋嵌入式衬塑钢管具有不分层、不缩管，长期使用有保障的技术特点。并于2001年获国家实用新型专利。这种独特的工艺生产效率高，过程控制易行，复合质量高ssure in the 2.0mpa can basically meet the building water pressure requirements and thickness design of the important parameter of this parameter. temperature is also an important parameter pipe design is used, it determines the permissible stress of the material. in the industry, according to the movement of water temperature is pided into cold water and hot water, cold water temperature is 0 c ~25 c, exposed piping under the influence of atmospheric temperature medium temperature, summer temperatures can be as high as 40 degrees celsius in southern china, and temperatures below-40 ° c in the winter in the north, but water from solidifying into ice below 0 c, which fall short of water for purposes. in the industry there are some specifications of the insulation so that the temperature of the water in the pipe kept at 0 ° c or above in order to keep fluids flowing. generally used for heating, shower with hot water, the water temperature is usually below 75 deg, instantaneous temperatures of up to 95 ℃. these surveys, tendons embedded in plastic-lined steel pipes are pided into two major categories of cold
