Insist on humanized design and devote ourselves to improving the quality of anticorrosive and heat preservation pipeline products!
The prefabricated direct buried tees refer to tees for main pipes, branch pipe fittings, and pipe joints. Reducing tee is a kind of tee. The tee has a common equal tee and a reducing tee. How to connect prefabricated buried tees?
Because the three endpoints can be named after connecting to the pipeline. The same diameter at both ends is called equal diameter tee.
Prefabricated direct buried tees are widely used in the construction and overhaul of petrochemical, oil and gas, liquefied petroleum gas, fertilizers, power plants, nuclear power, shipbuilding, papermaking, pharmaceuticals, food hygiene, urban construction and other industries.
When connecting the prefabricated direct buried tees, connect the pipe fitting and the flange pipe fitting to the pipe end.
There are holes in the flange, and the bolts tightly connect the two flanges. The flange is sealed with a gasket. Prefabricated buried tees are pipe fittings with flanges. It can be cast or made by screws or welding.
It consists of a pair of flanges, a washer and bolts and nuts. The gasket is placed between the two flange sealing faces. After tightening the nut, the specific pressure on the surface of the washer reaches a certain value, then it deforms and fills up the unevenness on the sealing surface, making the joint tighten. Flange joints are removable joints.
The prefabricated buried tees can be divided into topping, pressing, forging and casting according to the production methods. The specifications of prefabricated direct-buried reducer tees are generally 25 * 20, 32 * 20, 32 * 25, 75 * 63, etc., and there are corresponding flange connections and accessories.
