FAQs of Transition Curve Pipe Fitting

1. What is the difference between Transition Curve Pipe Fitting and Transition Curve Fitting?

A Same-Diameter Transition Joint has the same size at both ends. A Reducing Transition Joint has different sizes at each end.

The same-diameter joint is used to turn or connect pipes of the same size. The reducing joint is used to connect pipes of different sizes and control the flow.

Choosing the right type depends on the main needs of the B2B customer, such as pipe sizes, fluid type, and where the pipe will be installed.

2. Can Transition Curve Pipe Fitting be used on soft substrates?

Transition Curve Pipe Fitting can be used for soft substrates. Soft base materials include PVC and aluminum alloy pipes, among others. But it needs to be used with a customized structure or special accessories. When using transition joints with soft materials, pay attention to two things:

Choose seals that match the hardness of the material. Hard seals can press too much and damage soft materials.

Control how tightly you screw the joint. Don’t use too much force, or the soft material can bend or get damaged.

3. Can Transition Curve Pipe Fitting be installed or removed under pressure?

Do not install or remove a regular Transition Curve Pipe Fitting while the system is under pressure. Only a specially made “Pressure Operated Transition Fitting” can be used in that case.

Using a regular fitting under pressure can break the seal or damage the pipe. If you cannot turn off or release pressure in industrial systems, you need a specially designed fitting that works under pressure.

4. Can you provide Transition Curve Pipe Fitting installation instructions?

Plumberstar is a professional factory for valves and pipe fittings. We provide complete installation guidance and technical support for global B2B customers using Transition Curve Pipe Fittings.

We give a paper installation manual with technical data, and we also have installation videos.

Before installation, customers give us their pipeline system details and can ask us if it will work in their conditions. During installation, we support questions and help check installation quality. After installation, we explain how to maintain the system, guide daily maintenance, help troubleshoot problems, and suggest solutions.

5. How fluid compatible is Transition Curve Pipe Fitting?

The way a Transition Curve Pipe Fitting works with different fluids depends on the material and seals used. Different materials handle different fluids, like water, gas, oil, or chemicals. You also need to consider the working conditions.

• 304 stainless steel is the most common and works for clean water, softened water, and similar liquids. It can handle seawater or chlorine water for a short time, but for long-term use or high chlorine, 316L stainless steel is better.

• Brass joints are cheaper and good for plumbing, tap water, hot water, and non-corrosive gases.

• PVC joints are light and resistant to corrosion, suitable for water supply, drainage, and some chemical liquids.

B2B customers should give detailed working conditions when choosing a model. Plumberstar can meet most industrial and plumbing needs with standard materials and custom options. We also provide material inspection reports and fluid compatibility checks to make sure the pipeline works safely for a long time.

6. What should be noted when transition curve pipe fittings are used to transport corrosive media?

When transporting a corrosive medium, in addition to the material, it is also necessary to control the dimensions of sealing parts and structural design to avoid problems such as medium leakage and joint damage, ensuring the stable operation of the transportation system.

Seals are the most important part for stopping leaks. The seal material must match the liquid. For very strong acids, alkalis, or organic solvents, use FKM or PTFE seals. Do not use nitrile rubber seals with chlorinated oils, because they can corrode and age quickly.

The shape of the seal also matters. Under high pressure, use a retaining ring to stop the seal from being pushed out or deformed, which can cause leaks.

A bad design can leave liquid in the joint or put too much stress on it, which speeds up corrosion. To prevent this:

• You can choose a lined joint so the liquid does not touch the joint body.

• Control the joint surface carefully. Use a labyrinth seal with gaps ≤0.1mm and surface roughness ≤6.3μm to stop local corrosion.

• Make sure the joint walls are strong enough. They should handle 1.5 times the design pressure to prevent thinning and breaking.

This way, the joint stays safe and strong even with corrosive liquids

7. How to choose the turning angle of the transition curve joint?

The transition curve pipe fitting, which involves selecting the same-diameter joint steering angle, must be combined with the installation space size, fluid characteristics, operating pressure level, and later maintenance requirements to make a comprehensive judgment.
The installation space is compact, and the short radius 90° joint is preferred. The space is extremely narrow, and the 45° joint combination steering can be adopted.
Open space, optional long radius 45°/90° joint;
Common clean fluid can be used for a 90° joint to achieve a right-angle turn or 45° to create a smooth connection.
An 180° folding joint shall be selected for turn-back transmission, and a 0°-90° adjustable angle joint shall be selected for flexible angle adjustment to ensure steering adaptation in the scene without affecting fluid transmission efficiency or joint service life.
