双金属复合管特点:
Features of bimetallic composite pipes:
1、具有良好的机械性能:
1. It has good mechanical properties:
由于内外两层均为金属材料,所以其抗压、抗冲击性强,抗拉强度大,伸长率高,弹性模量值高,热膨胀系数小,尤其适宜高层建筑给水的立管与支管用。
Because both two layers are metallic materials, they have high compressive strength, impact resistance, high tensile strength, high elongation, high modulus of elasticity and small thermal expansion coefficient. They are especially suitable for risers and branch pipes of high-rise building water supply.
2、结合强度高:
2. The combination of high strength:
内衬不锈钢复合管是将内层的不锈钢管套入碳钢管内,在机械挤压力的作用下,外层碳钢管处于弹性变形,内层不锈钢管达到塑性变形,使两层材质紧密嵌合,其结合强度超过国家行业标准的规定,达到lMPa以上,由于内外层材质相近,结合力强,所以在压槽、切割时不会产生两种材料剥离现象,杜绝了电偶腐蚀的发生。
Stainless steel lined composite pipe is a stainless steel tube inner carbon steel pipe in mechanical extrusion under pressure, the outer layer of carbon steel in the elastic deformation, plastic deformation of inner stainless steel tube, the two layer material tightly fitting, the bonding strength than the national industry standard specification, reach more than lMPa, because of the inner and outer layers of material similar, strong binding force, so it will not in a pressure tank, cutting two material peeling phenomenon, to prevent the occurrence of galvanic corrosion.
3、防锈耐腐蚀性好:
3. Antirust and corrosion resistance:
不锈钢材质由于具有防锈和耐氧化、耐酸碱、耐晶间腐蚀性良好等化学性能,其防锈和防蚀性能比其它材质优越。内衬不锈钢复合管和内衬不锈钢复合管件配套连接,其适用范围更为广泛,主要用于供水、供热、空调、消防、化工、医药、石油、食品、电力、冶金等防蚀要求高的行业。
Stainless steel is superior to other materials because of its chemical properties such as rust protection, oxidation resistance, acid and alkali resistance and good intergranular corrosion resistance. The inner lined stainless steel composite pipe and the inner stainless steel composite pipe fittings are connected together, and the application scope is more extensive, which is mainly used for the industries with high corrosion resistance, such as water supply, heating, air conditioning, fire fighting, chemical engineering, medicine, petroleum, food, electric power, metallurgy and so on.
4、耐热耐寒,冷热两用:
4, heat resistant and cold, cold and hot dual use:
耐温不锈钢材质工作温度可达到-40℃-350℃。耐寒性能也很好,比如液氯冷冻箱就采用不锈钢,所以内衬不锈钢复合管耐热耐寒性能优越,而且不分冷热水管,一管二用,冷热皆宜。
The temperature of temperature resistant stainless steel can reach -40 C -350 C. Cold resistance is also very good, such as chlorine on the freezer using stainless steel, so the heat and cold resistance of stainless steel lined composite pipe is superior, and regardless of hot and cold water pipes, a pipe two, hot and cold safe.
5、通径大,阻力小:
5, the path is large and the resistance is small.
内衬不锈钢复合管其内层不锈钢仅有0.25~0.7mm,所以实际通径与规定通径基本相符,而且内壁光滑、卫生、不结垢、阻力小、流水量大。
The inner stainless steel composite pipe has only 0.25 ~ 0.7mm of inner stainless steel, so the actual diameter is basically consistent with the specified diameter, and the inner wall is smooth, sanitary, no scaling, small resistance and large flow volume. |
