Product details
The Slip On Flanges is a kind of flange which is loose on the flange of vessel or pipeline. Flange is a part connecting shaft and shaft, which is used to connect pipe ends; It also uses the flange on the equipment inlet and outlet to connect the two equipment.
TheSlip On Flanges is a loose flange. The flange can be made by flanging, directly turning out or welding ring. The advantages are that when the flange deforms, there is no additional torque on the container or pipeline, and the manufacturing is convenient. It can be made of different materials from the container or pipeline, which is convenient to save precious metals. The disadvantage is that the flange is thick. It is suitable for vessel or pipeline lining with brittle material and low pressure.
How does TheSlip On Flangeswork?
The TheSlip On Flanges must be slid into the pipe before welding. In this case, it is double welded inside and outside, thus providing the durability required to avoid leakage. Their pressure rating is about 2 / 3 of that of welding neck flange. Slide in flanges are suitable for low pressure applications and are easy to install and weld to different pipes. In addition, welding helps to reduce manufacturing costs.
The TheSlip On Flanges does not need to leave a large longitudinal space in the pipeline to be installed. In addition, they do not need to be cut accurately in the pipe, and alignment is less difficult.
In order to ensure that the flange is not leaking, what problems should be paid attention to during installation?
1. The flange shall have sufficient strength and shall not deform during fastening. Flange sealing surface shall be flat and clean, and oil stain and rust shall be carefully cleaned during installation.
2, gaskets should have good oil resistance and anti-aging properties, as well as better elasticity and mechanical strength. The gasket with different section and size should be selected according to the shape of the joint and placed correctly.
3. The tightening force of flange should be uniform, and the compression of rubber pad should be controlled at 1 / 3.
