Described linkage structure is the flange plate that is welded on the bend pipe end, this flange plate inner ring and four-way pipe end diameter coupling, and the carbon steel layer of this flange plate inner ring and four-way pipe is integrally welded.
The beneficial effects of the utility model
1, combination property height
Outer carbon steel and the internal layer of adopting of this compound threeway and four-way pipe adopts rich chromium cast iron, formed metallurgy combination preferably, wear-resisting, the corrosion resistance characteristic that had both had high chromium alloy material, higher mechanical strength and higher shock resistance are arranged again, the weldability that single material is difficult to be in harmonious proportion and the contradiction of wear resistance have been solved, make the material property advantage perform to optimum degree, safe and reliable.
2, wearing layer adopts high chromium cast iron material, improved the wear resistance of three-way pipe and four-way pipe internal layer greatly, this abrasion-proof bent tube is an integral molding in addition, compare with the pipeline of welding in the past, resistance is less, and corresponding material is also little to the friction of inner-walls of duct, comprehensive, wear resistance improves many, and can reduce energy consumption.
3, shaking property of heat resistanceheat resistant is good
Because the internal layer of this three-way pipe and four-way pipe is suitable with outer field thermal expansion coefficient, when having temperature rapid change or welding to connect, can or shrink inconsistent and cause that wear-resisting inner tube layer is cracked to be peeled off, the generation early failure phenomena because of the expansion of internal and external layer.
4, transportation, installation, easy to use
This bimetal composite wear resistant three-way pipe and four-way pipe can adopt modes such as flange, rapid pipe joint, direct welding to install.Because its shock resistance height when local plugging takes place pipe-line system, can arbitrarily knock, beats, unload and change, weld, install, overhaul very convenient.
