直埋式黑夹克保温管厂家消费规范
Consumer Specification for Direct Buried Black Jacket Insulation Pipe Manufacturers
直埋保温管功能：直埋保温管具有良好的机械功能和绝热功能，通常状况下可耐低温120℃经过改性或与其它隔热资料组合可耐低温180℃，适用于各种冷、热水上下温管道的保温工程。
Function of directly buried insulating pipes: The directly buried insulating pipes have good mechanical function and thermal insulation function. They can withstand low temperature 120 ~C under normal conditions, and can withstand low temperature 180 ~C when combined with other insulating materials. They are suitable for all kinds of insulating projects of cold and hot water pipelines.
直埋保温管使用：直埋保温管普遍用于液体、气体的保送管网，化工管道保温工程石油、化工、集中供热热网、地方空调通风管道、市政工程等。直埋保温管是一种保温功能好，加平安牢靠，工程造价低的保温管道。无效的处理了城镇集中供热中的130℃－600℃低温输热。直埋保温管不只具有传统地沟和架空敷设管道难以比较的技术、适用功能，而且还具有明显的社会效益和经济效益，也是供热的无力措施。
Use of directly buried heat preservation pipes: directly buried heat preservation pipes are widely used in liquid and gas pipeline network, chemical pipeline heat preservation engineering petroleum, chemical industry, central heating network, local air conditioning and ventilation pipeline, municipal engineering, etc. Direct buried insulation pipe is a kind of insulation pipe with good thermal insulation function, safety and reliability, and low cost. Invalid treatment of low temperature heat transfer between 130 ~600 in urban central heating. Directly buried insulation pipe not only has advanced technology and applicable function which is difficult to compare with traditional trench and overhead pipeline laying, but also has obvious social and economic benefits, and is also a weak measure of heating energy saving.
直埋保温管施工中罕见成绩及处理方法：
Rare achievements and treatment methods in construction of directly buried insulating pipes:
1、直埋保温管起发速度慢；此景象普通呈现在秋夏季节或晚上施工，由于气温忽然降低或气温低所致。将环境温度、黑料温度降低即可处理。普通将黑料温度升30-60℃，环境温度升20-30℃即可。
1. The starting speed of directly buried insulating pipes is slow; this phenomenon usually appears in the construction in autumn and summer or at night, due to the sudden drop in temperature or low temperature. The environmental temperature and black material temperature can be reduced to be treated. Usually, the temperature of black material is raised to 30-60 C, and the ambient temperature is raised to 20-30 C.
2、直埋保温管起发速度快；此景象普通呈现在春冬季节或半夜施工，由于气温忽然降低事气温太所致。可将黑料用冷水泠却或夜间放在室外自然冷却，防止太阳直晒。
2. The starting speed of directly buried insulating pipes is fast; this scene usually appears in spring and winter or midnight construction, because the temperature suddenly drops and the temperature is too low. Black material can be cooled with cold water or left outside at night to cool naturally to prevent direct sunshine.
3、直埋保温管泡沫强度较小且泡沬较软；此景象由彩色料比例失调惹起，适当增大黑料比例即可(1：1—1.05)留意不在使黑料比例太大，否则，会使泡沬变脆，亦影响泡沬功能。
3. The burial strength of the directly buried insulation pipe is small and the foam is soft. This scene is caused by the imbalance of color materials. The proportion of black materials can be increased appropriately (1:1 - 1.05).
