How to choose the pipe fittings?
Table of Contents
In complex piping systems, fittings play a key role in enabling two or more sections to connect seamlessly. And they can do much more than that. Fittings provide additional flexibility, allowing system users to extend pipework or change the direction of flow within a pipe to suit specific needs or to suit the design of a building.
The versatility of fittings allows them to serve a wide range of industries, including water supply, pharmaceuticals, power generation, petrochemicals, and pulp and paper. Water supply pipe fittings are particularly important, as choosing the right fittings not only improves the efficiency of water flow, but also reduces the likelihood of leaks. For this reason, water supply pipework offers a wide range of fittings in a variety of materials, types, shapes and sizes to cope with every possible requirement.
JHY Group understands the variety of fittings required for water supply systems, and because of this, JHY Group offers a range of mechanical fittings options to suit the most common types of pipework used in water supplies.
01 Fitting Selection Criteria
02 Selecting Pipe Fittings Based on Pipe Material
Various types of pipelines are utilized in water supply systems, the most common of which are Polyethylene (PE), Cross-linked Polyethylene (PEX), Polyvinyl Chloride (PVC), Ductile Iron, Copper, Plastic, Asbestos Cement (AC), and Galvanized or Stainless Steel pipes. The selection of pipe fittings necessitates a consideration of the type of pipe and its material. Here, let’s discuss some common pipe fittings we offer at JHY with reference to these pipeline materials.
03 Flange fittings
Flange fittings are a commonly used type of pipe fitting. They connect pipework equipment such as pipes, valves and pumps by screwing them together. A flanged joint is formed when two flanges are bolted together and a gasket is used to form a seal between them.
The choice of flange connection type depends on the system and application, with temperature and pressure being key factors. Flanged joints are commonly used in water supply networks and are compatible with most common types of pipework. They are easy to use, versatile, fit into tight spaces and are ideal for rigid pipework. In addition, they are simple to maintain due to the ease of disconnecting and reconnecting.
04 Selection of fittings according to pipe diameter
Water supply pipelines can vary greatly in diameter. This variation is typically dictated by factors such as the specific region, the type of pipe material used, and the overall design of the pipeline. As an example, in a water supply system, the main pipelines (also referred to as water mains) will usually have a diameter larger than DN 400. On the other hand, the distribution lines start from DN 50, while service lines, which are the connections running from the water main to individual houses, will generally have a diameter smaller than DN 50.
05 Large Diameter Pipeline Connections
Large diameter pipeline connections are integral components in efficiently managing extensive fluid transportation systems, such as those found in oil and gas or water supply industries. One of the significant elements in these connections is the removable joint. These joints, designed for easy attachment and detachment, help preserve the pipeline’s integrity while simultaneously facilitating its assembly, maintenance, and repair. By ensuring a secure seal, removable joints prevent leaks, bolstering the system’s overall efficiency.

06 Elbow Fittings
Elbow fittings play an essential role in the structure of pipeline systems, providing the ability to modify the angle and direction of fluid flow, with bends typically reaching 11°, 30°, 45°, and 90°. These components are integral to the intricate design layouts of water supply networks that require changes in direction. JHY, a trusted brand in the industry, boasts a vast assortment of these elbow fittings. Whether your system requires an 11°, 30°, 45°, or 90° bend, JHY has the expertise and range to cater to your specific needs.
