No thrust rotary expansion pipe product introduction
No thrust rotary expansion pipe not only opened a new field for the expansion of production, more important is that it not only solve the thrust Achilles' heel of the working medium inside the pipeline, but also solves the by-pass pipe type zero thrust expansion stress concentration, medium resistance big drawbacks.

No thrust rotary expansion scope
ZTWB series oil type dc no thrust expansion of medium, can be widely used in chemical, oil, thermal power, metallurgy, urban centralized heating pipe network, such as cooking and overhead pipeline. At the same time, is advantageous for the pipeline design, easy installation, and save a large number of funds (fixed support only a cost 60 ﹪ above). At present, ZTWB and TWB series oil type dc medium without thrust expansion, proved by users, its advantage has been preliminarily proved that is superior to other similar products.

No thrust rotary expansion pipe installation instructions
(1) with the expansion pipe ends when the welding section thickness of 6 mm or higher, groove processing, must be conducted according to the requirement of hydraulic leak test after welding.
(2) the sliding bracket and fixed bracket according to the design and installation, use ZTWB type, besides don't calculate work medium pressure thrust, the rest is the same. To ensure that the pipeline without lateral displacement, and along the axial expansion, expansion pipe ends shall generally be sliding bracket, installation guide on the pipe bend, you must install the fixed bracket.
(3) the expansion of thermal protection structure with pipeline route, but the extension tube telescopic part, do not produce binding.
(4) the expansion pipe under various environment temperature, can be installed according to the maximum length LMax to, do not need to be stretched or compressed.
