DMH UNITED STEEL INDUSTRY has provided customers with high quality oil casing, oil pipeline, seamless steel tube and seamless steel pipe for many years. The products are of high quality and low price, and customers are welcome to choose them.


Oil casing:

Execution standard: one is made up of super fine glass wool, which is filled with conveying medium steel pipe, anticorrosive coat steel pipe and steel pipe and outer steel pipe. It can also be made of graphite, calcium silicate tile and shell and polyurethane foam. The burying technology of steel casing (steel sleeve steel) is a new technology of waterproof, leak proof, anti-seepage, compression and totally enclosed. It is a great breakthrough in the application of directly buried technology in the high groundwater level area. The first problem is the protection of buried pipe pipe reliability strict waterproof, in addition to have good mechanical strength, high strength steel casing due to the use of welded connections, waterproof sealing performance reliability is very high, in addition, the high temperature performance and other external protective tube can match the. In the area where the groundwater level is high, in order to ensure that the underground water does not affect the normal operation of the steam directly buried pipeline, the outer protective layer is preferably built with a strong and tightly sealed steel tube shell.


Oil casing insulation structure based on sliding mode is divided into: sliding and sliding type 1, sliding type thermal insulation structure by: steel, aluminum silicate, calcium silicate, drag layer, insulating layer, stainless steel fastener, aluminum foil reflective layer, polyurethane insulation layer and the outer sleeve, anti-corrosion layer. 2, the external sliding type: the insulation structure is composed of working steel pipe, glass wool insulation, aluminum foil reflector, stainless steel fastening belt, sliding guide bracket, air insulation layer, external protection steel pipe and external anticorrosive coating.

Oil casing is a superfine glass wool filled by combination between steel, medium anti-corrosion coat steel pipe and steel pipe and the outer steel tube and into, also can use graphite, calcium silicate tile shell and filled with polyurethane foam composite made of steel casing (steel) embedded technology is a kind of waterproof, leakproof, anti permeability compression and closed the laying of new technology, is a breakthrough in the use of technology of buried area with high underground water level, the primary protection of buried pipe pipe is the reliability of strict waterproof, in addition to have good mechanical strength, high strength oil casing due to the use of welded connections, waterproof sealing performance is very reliable in addition, the high temperature resistance and other external protective tube can not be compared, in areas of high ground water level, to ensure the water does not affect the steam pipe In normal operation, the outer protective layer is best used for sturdy, closed steel pipe shell.
