Benefits of technology

In this patented process, there was proposed an improved way to cast high diameter pipelines through two layers - once or twice during rotation on both sides of a special machine called a twist off center spinning system (TSC). By combining these techniques together, it becomes possible to create larger tubular products without having any issues like sandwiched between different materials due to poorly formed surfaces caused from previous methods such as manually painting or applying paint beforehand. Additionally, TSC allows for precise control over the thickness of each layer being produced, ensuring reliable performance even when subjected to severe environments where particles may damage them. Overall, this new technique simplifies manufacture processes while maintaining excellent results compared to existing ways.

Problems solved by technology

This patents describes various technical solutions aimed towards preventing damage caused by abrasion and corruption in buried assets like pipes while maintaining durability against chemical attack. Specifically, these techniques involve combining multiple layers of protectors onto each component separately, which increases costs compared to traditional ways alone. Additionally, current methods require expensive tools and complex processes involving complicated steps, leading to increased downtime and reduced operational effectiveness.

Embodiment 1

[0045] Embodiment 1: For DN600 equal-diameter right-angle tee pipe (see figure 1 , figure 2 ) to make this method (unspecified units are mm, the same below)

[0046] a. Fabrication of metal-ceramic composite pipe DN600 equal-diameter right-angle tee fittings

[0047] Cut the metal-ceramic composite steel pipe with an outer diameter of 630, a steel pipe wall thickness of 12, and a ceramic layer thickness of 6, grind and splice it into the required tee, and form it by electric welding. The three-port flange is installed and welded by electric welding. The side lengths from the center of the three-way pipe fitting to the three ports are the same, both a=b=c=500, and a and b are on the same straight line, so this straight line segment is selected as the axis for rotation during resin casting.

Abstract

The invention relates to a manufacturing method for a large-caliber abrasion-resistant corrosion-resistant ternary composite pipe accessory. The steps include that 1 a binary metal ceramic composite pipe fitting is manufactured, a metal ceramic composite steel pipe which is subjected to self-propagating high-temperature centrifugal synthesis (SHS) reaction is cut and welded in a spliced mode to form a required pipe fitting according to requirements; 2 abrasion-resistant materials are used for filling gaps of joints and mainly composed of abrasion-resistant inorganic particles and modified resin composite adhesives; 3 a separable double-layer mold is used for being lined in the inner cavity of a branch pipe, and inner surface resin layer pouring forming is conducted by combining a vacuum centrifugal pouring process. By means of the manufacturing method, the problem that a part of the composite resin layer of the ternary composite pipe accessory must be manufactured manually and can not be formed through machinery is solved, and the resin layer of the ternary composite pipe accessory and sealing face resin can be formed through one step. By means of the pipe accessory manufactured through the method, the resin layer is even in thickness, end product quality is stable and reliable, the service life is prolonged, application of an abrasion-resistant corrosion-resistant ternary composite pipeline project is guaranteed effectively, important project value is achieved, and production efficiency is improved.
