黑夹克直埋式直缝钢管具有杰出的机械功能和绝热功能
Black jacket straight seam steel pipe has outstanding mechanical and adiabatic functions
聚氨酯直埋保温钢管质量好,价格低,是集中供热的抱负产品.聚氨酯保温管起发速度快此现象一般出现在春夏时节或中午施工,由于气温俄然升高事气温太所致.可将黑料用冷水泠却或夜间放在室外天然冷却,防止太阳直晒.一级的出售人员,客户有询价的可打电话咨询或来厂调查.
Polyurethane direct-buried insulating steel pipe is an ideal product for central heating because of its good quality and low price. The rapid starting speed of polyurethane insulating pipe usually occurs in spring and summer or in noon construction. Because of the sudden rise in temperature, the temperature is too high. The black material can be cooled by cold water or naturally placed outdoors at night to prevent direct sunshine. Salesmen and customers who have inquiries can call for consultation or come to the factory for investigation.
聚氨酯发泡保温钢管聚氨脂直埋保温管又称“管中管”其有“两步法”构成，是由高密度聚乙烯外保护层、聚氨脂硬质泡沫塑管和钢管组成。
Polyurethane foam insulation pipe, polyurethane directly buried insulation pipe, also known as "tube in tube", has a "two step method" consisting of high density polyethylene external protective layer, polyurethane rigid foam plastic pipe and steel pipe.
1.防腐层：保护外钢管防止腐蚀物腐蚀钢管，延长钢管使用寿命。
1. Anti-corrosive coating: Protect external steel pipe from corrosive substances, prolong the service life of steel pipe.
2.外护钢管: 保护保温层免受地下水腐蚀，支撑作业管并能接受必定的外部荷载，确保作业管正常作业。
2. External steel pipe protection: to protect the insulation layer from groundwater corrosion, to support the operation pipe and to accept certain external loads, to ensure the normal operation of the operation pipe.
3.聚氨酯泡沫层: 确保介质温度，确保外护管表面坚持常温。
3. polyurethane foam layer: ensure the temperature of the medium and ensure the surface of the outer tube is kept at normal temperature.
4.阻隔、反射层: 确保有机泡沫资料不进入无机硬质耐高温层;反射耐高温层部分热量。
4. barrier, reflective layer: ensure that the organic foam data do not enter the inorganic rigid high temperature resistant layer; reflect the heat resistant part of the heat.
5.无机硬质保温层：耐高温，确保与有机保温层之间的界面温度，确保泡沫不被炭化。
5. inorganic hard insulation: high temperature, ensure the interface temperature between the organic insulation layer and ensure that the foam is not carbonized.
6.减阻层: 确保作业钢管热胀冷缩自在运动。
6. Drag Reduction Layer: Ensure that the hot expansion, cold contraction and free movement of the working steel pipe.
7.作业钢管：确保运送介质正常活动。
7. Operating steel pipe: Ensure the normal activities of transport media.
保温层资料为密度60kg/m3至80kg/m3的硬质聚氨酯泡沫，充沛添满钢管与套管之间的空隙，并具有必定的粘接强度，使钢管、外套管及保温层三者之间形成一个结实的全体。 聚氨酯发泡保温钢管泡沫具有杰出的机械功能和绝热功能，通常情况下可耐温120℃经过改性或与其它隔热资料组合可耐温180℃。保温层资料为密度60kg/m3至80kg/m3的硬质聚氨酯泡沫，充沛添满钢管与套管之间的空隙，并具有必定的粘接强度，使钢管、外套管及保温层三者之间形成一个结实的全体。
The insulation layer material is rigid polyurethane foam with density 60kg/m3 to 80kg/m3, which fully filled the gap between the steel pipe and the casing, and has a certain bonding strength, so that a solid whole can be formed between the three parts of the steel pipe, the outer sleeve pipe and the insulation layer. Polyurethane foam insulation steel tube foam has outstanding mechanical function and adiabatic function. Under normal circumstances, it can withstand 120 degrees of temperature and is able to withstand temperature of 180 degrees when modified or combined with other heat insulation materials.
