Nuts, stud bolts, washers, and machine tools are termed fasteners. Bolting is just useful to create flange joints to tighten the equipment. The tightening using flange ensures the leakproof and stable connection between flanges and gasket. Bolt Supplier Saudi Arabia has created a huge market over the choice of different kinds of piping fasteners.

ASME type of flanges has four holes for bolting and more diameter ranges, you simply require more holes. The selection of bolt holes depends on many factors like:

• Working pressure
• Flange size
• Flange Material
• Working temperature.

Different Fasteners In Piping:

Stud Bolt:
The stud consists of thread either for both ends or full-lengths. We know stud bolt has three components without a washer i.e., one nut and two studs. With a couple of washers, it becomes five. Sometimes, extra nuts are useful for hydraulic tensioning with larger studs.

The bolt length must be large enough to cover up the entire nut plus thread area. Do not prefer long stud as there is an increased chance for other damages like corrosion, atmospheric exposure, etc. These would make bolt removal quite difficult for us. The length will depend upon gasket type and thread requirements.

Machine Bolt:
Bolts consist of hexagonal heads and thread at different ends. Usually, Bolt Supplier Oman supplies piping bolts that are useful for the flanges with less strength. And washers take place to share excess load from the flange.

Nuts:
Commonly heavy series hexagonal nuts add studs. The load-bearing face looks like a finished washer face while the non-bearing face remains chamfered.

Washers:
You may have seen washers for the nuts having some clearance even after fitting with the slot. It tightens the load and distributes it with a flange face. This is also necessary to make the connection long-lasting

Bolt Supplier Kuwait prefers non-metallic flange with washers. Different types of washers are available in the market like split, flat, conical spring, etc. Split and flat washers are used on the maximum occasion.

Conical washers are also special, and these are also known as Belleville washers. It keeps the joints where differential expansion due to heat, creep, and vibration exists. Avoid such conditions as these would create a loose connection with the structure. Henceforth, conical washers are essential to prevent any stud loosening and the spring effect remains for flexible joints. This type of washer is very much a handful for high loads with small deflections.

Inspection of Piping Bolts:
Check the product quality and surface defect using visual inspection.

• Check out poor chamfered & damage thread for stud ends and nuts head.
The following details are to be confirmed for dimension inspection for stud bolts.
• Stud and bolt diameter
• Thread pitch
• Bolt and nuts dimension
• Length.

Stud Marking:
For ASTM A320 and A193 materials, stud & bolt are specifically marked. Either you choose bolt head or stud ends for the marking task.
Stud Bolts Manufacturer UAE marks the identification as per space and material guide. Various symbols and materials would help in marking.
Nut marking is also there based on the non-load bearing face of the nuts. More information regarding bolting is present in the manufacturer’s guide.
