Types of Pipe Fittings

01/

With Lap Stainless Steel Flange
Due to the different sizes of 304L stainless steel flanges, according to the unique welding position of stainless steel flanges, the heat input is reduced as much as possible.

02/

Stainless Steel Long Radius Elbow
Long radius is the most commonly used, and it is also the long radius by default. Where the pressure is high or the flow rate is high, long radius will be used.

03/

Stainless Steel Diameter Three Tee
The stainless steel tee has equal diameter and different diameter, and the connecting end of the equal-diameter tee is the same size; the main pipe of the different-diameter tee has the same size, and the connecting pipe of the branch pipe is smaller than the main pipe.

04/

Stainless Steel Diameter Four Cross
The stainless steel cross has the equal diameter and the different diameter, and the connecting ends of the equal-diameter four-way are all the same size.

05/

Stainless Steel Degree Elbow
The difference between the stainless steel elbow and the carbon steel elbow is mainly due to the difference in material.

06/

Stainless Steel Cap Cap
The cap is a pipe that is welded to the pipe end or to the external thread of the pipe end to cover the pipe. Used to close the pipeline and function the same as the pipe plug.

Advantages of Pipe Fittings

Durability and Longevity
Stainless steel pipe fittings is incredibly durable and resistant to rust, corrosion, and mechanical wear. This makes it ideal for plumbing systems that must endure long-term exposure to water and other fluids.

Resistance to High Pressure
Whether in a high-rise building or an industrial facility, stainless steel pipe fittings ensures consistent performance even in demanding applications.

Hygienic and Easy to Clean
Stainless steel pipe fittings has a non-porous surface, which prevents the buildup of bacteria and contaminants.

Fire and Heat Resistance
Stainless steel pipe fittings are fire-resistant and can maintain their performance even in high-temperature situations, making them an excellent choice for HVAC and fire protection systems.

Application of Stainless Steel Pipe Fittings

Chemical Processing Plants

Chemical plants need tough equipment. Stainless steel pipe fittings are useful in this situation. They do not corrode when exposed to strong chemicals.

Food and Beverage Industry

In the production of food, cleanliness is crucial. For this industry, stainless steel pipe fittings are ideal. They do not rust and are simple to clean.

Oil and Gas Sector

The oil and gas industry is tough on equipment. It needs fittings that can handle high pressure and extreme temperatures. Stainless steel pipe fittings fit the bill.

Pharmaceutical Manufacturing

Making medicine requires super clean conditions. Stainless steel pipe fittings are ideal for this. They don’t react with drugs and are easy to sterilize.

Power Generation Plants

Power plants need reliable equipment. Stainless steel pipe fittings provide that reliability. They can handle high temperatures and pressures.

Manufacturing Method of Pipe Fittings

Forging Manufacturing Method
Making method of stainless steel forged fittings,using forging machine bevels the stainless steel pipe end or extension, reduce the outside diameter. The common types are rotary, connecting rod and roller type.

Rolling Wheel Manufacturing Method
Stainless steel butt weld fittings, putting the core in the stainless steel pipe. Then pushing the external by roller and processing the rim.

Stamping Manufacturing Method
Using tapered core to expand the stainless steel pipe end to the required size and shape in the punching machine.

Bending Manufacturing Method
For making stainless steel elbow and bend fittings. There are three commonly methods. One is stretching , another is stamping , the third is roller , there are 3-4 rollers. Two fixed rollers and one adjusted roller. Then adjust the fixed rollers spacing and the finished product is bend.

Bulging Manufacturing Method
A rubber is placed in the tube and the top with a punch compression, then the pipe is bulged forming; Another method is hydraulic bulging forming. That is filling the middle of the pipe with liquid, the hydraulic will bulge pipe into the desired shape. This is the most common method for corrugated pipe production.

Pipe Fittings Installation Requirements

Avoid Contamination

Use clean tools, gloves, and work surfaces during the installation.

Use Compatible Tools

Avoid using tools made of carbon steel or other materials that can cause galvanic corrosion.

Avoid Over-tightening

Follow the manufacturer's recommended torque values to ensure a secure connection without compromising the integrity of the fitting or the pipe.

Thread Sealants

Ensure that the sealant is compatible with stainless steel and does not contain compounds that can cause corrosion.

Proper Alignment

Ensure proper alignment of pipes and fittings during installation. Use appropriate tools and techniques to achieve accurate alignment.

Avoid Mixing Metals

Avoid mixing stainless steel with other metals in the same plumbing system to prevent galvanic corrosion.

FAQ

Q: How tight should pipe fittings be?

A: A simple rule of thumb for installing tapered pipe threads, both metal and plastic, is finger tight plus one to two turns with a wrench. Be cautious of overtightening NPT and NPTF connections. FTHT (Fit to Hand Tight) is the threaded assembly screwed together hand-tight but without any sealant applied to the threads.

Q: How much thread goes into a pipe fitting?

A: 1-inch, 1 1/4-inch, 1 1/2-inch and 2-inch nominal pipe size have 11 1/2 threads per inch. 2 1/2-inch nominal pipe size and larger have 8 threads per inch.

Q: How to determine the size of pipe fittings?

A: For male pipe threads, be sure to measure the outside diameter at the widest point of the threads. For female pipe threads, measure the inside diameter at the widest point of the threads. You can then use these measurements to find the right size in a nominal pipe size conversion chart .

Q: How do I choose pipe fittings?

A: The points to consider are as follows: Consider the Tubing Used: For instance, barbed fittings work better in flexible tubing while compression fittings work best with rigid tubing. Determine Material Compatibility: Material selection plays a vital role in the proper working of fittings.

Q: What materials are pipe fittings made of?

A: Common materials include stainless steel, carbon steel, brass, copper, PVC, CPVC, and polyethylene, depending on the application and environmental conditions.

Q: What are elbows used for in pipe fittings?

A: Steel pipe elbow (sometimes also refereed as bends) is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree.

Q: What is the difference between a tee and a cross fitting?

A: Tee fittings are suitable when branching pipes in a single direction is required, while cross fittings allow for branching in multiple directions. A tee fitting has three connections forming a T-shape, while a cross fitting has four connections forming a cross.

Q: What are pipe plugs and caps used for?

A: A plug is a male threaded fitting which seals the end run of a pipe when fitted into a female threaded fitting. An cap is a female threaded fitting and is threaded over the end of a piece of pipe to seal it off.
