聚氨酯保温管验收应该注意哪些事项?

来源:http://www.sdhpgy.com 日期:2020-09-24 发布人:haipo
1.检查:聚氨酯保温管需要具备隔热、防水材料双重性能。材料进场后需要重新检查原材料。喷涂聚氨酯的复检内容主要包括材料的密度、压缩性能、尺寸稳定性和不透水性。
1. Inspection: polyurethane insulation pipe shall have double performance of heat insulation and waterproof materials. The raw materials need to be rechecked after entering the site. The re inspection contents of spraying polyurethane mainly include density, compression performance, dimensional stability and impermeability.
2.防水性能检测:使用储水或雨水检查其防水效果,不允许积水或漏水。
2. Waterproof performance test: use water storage or rainwater to check its waterproof effect, no ponding or water leakage is allowed.
3.喷涂厚度检查:使用钢针插入和测量的方法来检查厚度。
3. Spraying thickness inspection: use the method of inserting and measuring steel needle to check the thickness.
4.表面平整度检测:用1米直尺和楔形塞尺测量,允许偏差为5毫米。
4. Surface flatness detection: measure with 1 meter ruler and wedge feeler gauge, and the allowable deviation is 5mm.

5.硬质泡沫聚氨酯应与基层粘结牢固,表面不1得有破损、脱层、鼓包、孔洞和裂纹。
5. rigid polyurethane foam should be firmly bonded to the base layer, and 1 of the surface must be damaged, delaminated, bulging, holes and cracks.
6.聚氨酯保温管保温层任何位置的泡沫密度不得低于60千克/立方米。泡沫表面光滑、不粘、不收缩、泡孔均匀、无塌陷和开裂。
6. polyurethane foam insulation should not be less than 60 kg / cubic meter in any position. The foam surface is smooth, non stick, no shrinkage, uniform pores, no collapse and cracking.
7.逐一检查钢管表面预处理质量。管材表面应无油污和灰尘。除锈质量应与《涂装前钢材表面锈蚀等级和除锈等级》标准版本进行目视比较,不得低于sa2级。
7. Check the surface pretreatment quality of steel pipe one by one. The surface of pipes shall be free of oil and dust. The derusting quality shall be visually compared with the standard version of "rust grades and derusting grades of steel surface before coating", and shall not be lower than SA2 grade.
8.逐一检查钢管防腐涂层的质量。防腐层外观应均匀连续且无渗漏。防腐层的厚度应使用磁性测厚仪检查,保证厚度应小于设计厚度。
8. Check the quality of anti-corrosion coating of steel pipe one by one. The appearance of anticorrosive coating shall be uniform and continuous without leakage. The thickness of anticorrosive coating shall be checked by magnetic thickness gauge to ensure that the thickness is less than the design thickness.
9.保温层应无收缩、收缩、不均匀气泡、烧芯等缺陷。
9. The insulation layer shall be free from shrinkage, shrinkage, uneven bubble, core burning and other defects.
