The T-bracket (stiffened welded form) is the connection between the pipe and the steel structure or concrete support supporting the pipe. It acts as a supporting (dragging) pipe and is a form of support. 1. Low thermal conductivity, good cold breaking and heat preservation :2. Stable volume at ultra-low temperature (below -163°) and high temperature; 3. High compressive and flexural resistance; 4. Low moisture content; 5. Good flame retardant; High pressure injection grinding molding, with various thickness and layers, to meet the requirements of various cold temperature; 7. Each component is managed and assembled into a solid single structure in the manufacturing plant with a long service life; 8. Installation on site is fast, simple and safe, without changing the pipeline; Standardized manufacturing, reliable quality, fast supply; Design, more than 10 kinds of specifications for various levels of technology and economic demand choice, pipe bracket is also divided into insulation (cold) and not heat preservation of heat preservation is called directly support which is used in normal temperature pipe, also called pipe insulation (cold) - shoe no matter whether the heat preservation can be divided into sliding, fixed, guide, no matter choose the kind of, tube is the same, just in the pipe bracket and the steel structure or stent link change, by sliding and guidance in the form of pipe bracket use four fluorine board and four fluorine board sliding friction, or white steel plate with four fluorine board sliding friction, in order to reduce the friction coefficient, reduce the pipeline when the deformation or displacement, The binding force of the pipe holder on the pipe and the relative displacement between the pipe holder and the pipe should be avoided as much as possible.
