DIAMETER RANGE : Imperial : 3/8" to 4"
Metric : M10 to M100
LENGTH : Imperial : upto 10 feet
Metric : upto 3 meters
How To Measure
Stud bolt length is determined by the measurement from the first full thread to the last full thread.
The first and last full thread is determined as the intersection of the major diameter of the thread
with the base of the point. (refer to the diagram).
Diameter
Length
Material
Studbolt for high pressure - temperature
Chemical and mechanical requirements should be specified at the time of purchase and
will be in accordance with ASME, ASTM, and ANSI codes and specifications as
applicable at the time of ordering.

Points
Points are flat and chamfered, or sheared at option of the manufacturer. When points are flat
and chamfered, the diameter of the flat shall not exceed the minor diameter of the thread, and
shall be not less than one or more than two complete threads as measured from the extreme end
parallel to the axis.
Threads
Threads are Unified inch coarse thread series (UNC), Class 2A, for all stud bolt sizes 1 inch
and smaller, and Unified inch 8 thread series (UN8), class 2A, for all stud bolts larger than
1 inch, in accordance with ANSI/ASME B1.1. Acceptability of screw threads is determined
based on ANSI/ASME B1.3.

Influence Of Chemicals In Steel
Steel alloys using difference chemical elements are produced in order to improve the physical
properties of the material and to achieve special properties:
Carbon (C)
Although this is not considered to be an alloying element, it is the most important component in
steel. It improves tensile strength, hardness and abrasion resistance. It reduces ductility, rigidity
and machining.
Manganese (Mn)
This is an oxidiser and degasifier and reacts with sulphur to improve forgeability. It increases
tensile strength, hardness and durability.
Phosphorus (P)
This increases tensile strength and hardness and improves machinability. It causes fragility in steel.
Sulphur (S)
Improves machining qualities in the presence of manganese. It reduces weldability, impact,
roughness, and ductility.
Silicon (Si)
This is a deoxidiser and degasifier. It increases tensile strength, elasticity, hardness and forgeability.
Chromium (Cr)
Increase breaking strength, hardness, durability, roughness, and resistance to high temperatures.
Nickel (Ni)
This raises strength and hardness, while maintaining ductility and rigidity. It increases resistance
to cracking and high temperatures.
Molybdenum (Mo)
This increases strength, hardness, durability, and rigidity, together with resistance to creaking
and to high temperatures.
Titanium (Ti)
This is used as a stabilising element in stainless steels. It has a great affinity for carbon.

Preparation For Assembly
1. The gasket seating surfaces should be inspected for cracks, scratches, tool marks or pitting. If necessary
rework the flanges.
2. Clean and inspect each studbolt and nut. Nuts should run freely on the studbolt.
3. Make sure that compatible materials of studbolts and nuts are used.

4. Lubricate all studbolts and nuts with suitable parting lubricants or anti-seize compounds, including all
thread contact areas and nut faces in the process. Different lubricants produce changes to the coefficient
of friction between the bolt and nut threads. Approximate values are shown in the following table.
However, note that surface finish of flanges may also affect these values.

For a given torque, clamping load applied by the studbolts and nuts increases as the coefficient of friction
decreases. And a lower coefficient of friction means a better chance of producing reliable joints.
5. Inspect the gasket for any damage or imperfections and ensure the gasket is suitable for the flange
operating conditions of temperature, pressure and material being sealed.
Assembly And Tightening
During Assembly, gaskets are usually placed between the flanges being bolted. First, roughly align
the gasket in the joint by inserting a few bolts at the top of the flange. Then, lightly tighten all the
other bolts. During the Tightening process the correct sequence (as illustrated below) should be used.
Tightening should be continued in a clockwise manner until the desired torque is achieved. If using a
torque wrench make sure it is properly calibrated.

Tightening Torques
In the following pages tightening torque figures are calculated for the studbolt range. We have assumed coefficient of
friction of 0.20, and torque figures have been generated for clamping loads of 30%, 44% and 60% of yield loads.
Adjustments where necessary should be made. Tightening torque is calculated as T=KDP, whereby T = Tightening
Torque, K = Coefficient of Friction, D = Diameter of Stud Bolt and P = Induced Load.
.
Common industry practice for industrial bolting is to specify tightening torques to develop clamping loads of
60% to 65% of yield load. However, for studbolts, field experience suggests that clamping loads of more than
44% of yield load may cause deformation of flanges and difficulty in sealing joints. This fact should be accounted
for in estimating tightening torque values. Some authorities adopt the flange deformation stress as the controlling
factor. This allows the selection of single bolt stress value for a range of pipe classes even if different bolt types are
in use.
