16.Oil storage in ports: thermal insulation for the media pipes and freeze protection for water pipes.港口码头油库介质管线的伴热保温和水管线的防冻。 17.Code for construction and acceptance of coating defects on external anti-corrosive and thermal insulated coatings for buried steel pipeline埋地钢质管...
2 has four flow pipes 4. In such a case, two of the pipes are typically made of cross-linked polyethylene PEX equipped with an external oxygen diffusion protection layer and two are made of conventional unprotected cross-linked polyethylene PEX. The oxygen diffusion protected pipes 4 are then ...
3.The connection mechanism between insulation layer of external wall exterior insulation system and base course wall is studied.介绍国内常用的4种外墙外保温体系———混凝土外墙复合现浇浅槽聚苯板外保温体系、粘贴聚苯板外保温体系、混凝土外墙复合现浇聚苯板外保温体系与机械固定聚苯板外保温体系,研究外墙外保...
fluid vapor barrier to fluids that are external to and surrounding the laminate jacket pipe insulation product100. For example, the foil or metallized polymeric film sheet206is nearly impermeable to water vapor, which protects the insulated pipe from water condensation, corrosion, loss of insulating ...
It is aimed at protecting the tissue casing of thestructure from dammage thereto when the external tube is fit on the innertube previously provided with said plates and spacers 12. As shown, this foil 13 is comprised of an organic substance sheet having anouter aluminium coating. However, it...
The feedwater pipe support unit has a circular cross sectional hollow unit inside a body and a plurality of through units. The plurality of modular feedwater pipes are inserted into the hollow unit. The plurality of through units are formed on an outer circumference of the hollow unit in a ...
Process and installation for making insulated pipes for underwater petroleum pipelines, wrapping plates of insulating material around an internal tube, by means of a flexible band held between rollers on arm. This system allows only a pressure orthogonal to the pipe surface to be applied, thus ...
