Our devotion to accuracy is why we stand out.

We know how frustrating it can be for customers to struggle and fumble with rolled angle rings that fail to hold a consistent diameter. It adds to assembly costs, disrupts production, slows delivery and can be downright disastrous for customers. With National Metal Fabricators, you can always expect perfectly fitted rings.

At National Metal Fabricators, we produce custom rolled rings of any size, and we stock angle rings ranging from 3 inches to 48 inches in diameter. We are known for producing the most accurate rolled-angle rings available.

We’ll roll rings from angle, flat bar, channel, tee’s, round rod and selected pipe sizes; most commonly in carbon steel, stainless steel, and aluminum. At National Metal we can custom-roll angle rings up to 5 X 5 X ½ in carbon steel and 4 X 4 X ½ in stainless steel.

Choosing the correct weld nuts to complete your application depends on various factors including:

Application type
Parent material
Weld nut material
Type of welding
Base design

Weld nuts from China Longteng Pipeline Equipment Co.,Ltd Fasteners are available in many configurations including round, slab, and tab base weld nuts. The hex weld nut design is ideal for heavy duty applications whereas a tab nut is typically used for lighter jobs. A right angle weld nut attaches to the parent material and creates a threaded hole vertical to base material. Weld nuts have a critical design in that accurate pressure and current must be used during the welding process in order to secure optimal performance in after market use.

Typical weld nuts are manufactured in a low carbon steel with a plain finish. However, other materials, such as stainless, are available depending on the parent material in the application. Weld nuts are available with either inch or metric threads. JHP Fasteners distributes American, European, and American metric fasteners.

Your specific application will dictate the fastener material, size, and design. For more information on weld nuts and the various types provided by China Longteng Pipeline Equipment Co.,Ltd Fasteners, contact us. We’ll help you select the industrial fasteners you need to complete your applications.

Flange Of Types
A Flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed into such systems and then joined with bolts.
—————————————————————————————————————————————————
Weld Neck
This flange is circumferentially welded into the system
at its neck which means that the integrity of the butt
welded area can be easily examined by radiography.
The bores of both pipe and flange match, which
reduces turbulence and erosion inside the pipeline.
The weld neck is therefore favoured in critical
applications
Slip-on
This flange is slipped over the pipe and then fillet
welded. Slip-on flanges are easy to use in fabricated
applications.
Blind
This flange is used to blank off pipelines, valves and
pumps, it can also be used as an inspection cover. It
is sometimes referred to as a blanking flange.
Socket Weld
This flange is counter bored to accept the pipe before
being fillet welded. The bore of the pipe and flange are
both the same therefore giving good flow
characteristics.
Threaded
This flange is referred to as either threaded or
screwed. It is used to connect other threaded
components in low pressure, non-critical applications.
No welding is required.
Lap Joint
These flanges are always used with either a stub end
or taft which is butt welded to the pipe with the flange
loose behind it. This means the stub end or taft always
makes the face. The lap joint is favoured in low
pressure applications because it is easily assembled
and aligned. To reduce cost these flanges can be
supplied without a hub and/or in treated, coated
carbon steel.
Ring Type Joint
This is a method of ensuring leak proof flange
connection at high pressures. A metal ring is
compressed into a hexagonal groove on the face of
the flange to make the seal. This jointing method can
be employed on Weld Neck, Slip-on and Blind
Flanges.
