The sealing principle of the GT type interface of GT type ductile iron pipe is similar to that of the T type interface. As the internal pressure of the pipeline increases, the tighter the contact surface between the rubber ring sealing sleeve and the socket, the better the sealing effect.

The contact pressure generated by the compression deformation of the rubber ring acts as a self-sealing, and the hard rubber part of the rubber ring acts as a fixed centering function. The interface can be deflected to adapt to a certain foundation settlement and achieve long-distance steering installation.

When I am sizing lines for steam, process water, or mid-temperature hydrocarbons, I still find myself shortlisting Carbon Steel Pipes first.

The selection of urban water supply pipelines usually depends on the following factors: Material: Commonly used water supply pipeline materials include steel pipes, cast iron pipes, plastic pipes (such as PVC, PE, PPR), etc. Different materials have different characteristics, such as durability, corrosion resistance, and scope of application.

Pipe Fittings are fundamental connectors that construct the physical pathway of a piping system. They directly handle changes in flow direction (e.g., elbows), pipe diameter adjustments (e.g., reducers), flow splitting/merging (e.g., tees), or flow termination (e.g., caps). Their core role is to define and connect the routing and structure of the pipeline network. Pipe Accessories are components that extend functionality, enable control, and provide protection for the system. They regulate flow (valves), bear weight (supports/hangers), ensure sealing (flanges), purify fluids (strainers), monitor parameters (instruments), etc., with the core purpose of enhancing the system's safety, controllability, and operational efficiency.

The following points need to be considered when selecting a water meter: Measurement requirements: Select the appropriate water meter type according to the flow rate and accuracy requirements to be measured. Installation environment: Consider the environment in which the water meter is installed, such as whether special
