Types Of Bolts

In Petro and chemical industry for flange connections Stud Bolts and Hex Bolts are used. The Stud Bolt is a threaded rod with 2 heavy hexagon nuts, while the Hex Bolt has a head with one nut. Nuts and head are both six sided.

Stud Bolts General

The quantity of bolts for a flange connection will be given by the number of bolt holes in a flange, diameter and length of bolts is dependent of flange type and Pressure Class of flange.

Stud Bolt length are defined in ASME B16.5 standard. The length in inches is equal to the effective thread length measured parallel to the axis, from the first to the first thread without the chamfers (points). First thread is defined as the intersection of the major diameter of the thread with the base of the point.

Bolt Length

Notes:

  • The length of metric Stud Bolts measured parallel to axis, is the distance from each Stud Bolt, including the point.
  • To allow the use of hydraulic tensioning equipment, larger dimension studs shall be often one diameter longer than “standard”. That bolts to have plastic end cap protection.

Threads Of Stud Bolts

Bolts threading are defined in ASME B1.1 Unified Inch Screw Threads, (UN and UNR Thread Form). The most common thread is a symmetrical form with a V-profile. The included angle is 60°. This form is widely used in the Unified thread (UN, UNC, UNF, UNRC, UNRF) form as the ISO / metric threads.
The advantage of a symmetrical threads is that they are easier to produce and inspect compared with non-symmetrical threads. These are typically used in general-purpose fasteners.
Thread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter.

Standard Thread Pitches

  • Coarse thread series (UNC/UNRC) is the most widely used thread system and applied in most of the screws, bolts and nuts. Coarse threads are used for threads in low strength materials such as iron, mild steel, copper and softer alloy, aluminium, etc.. The coarse thread is also more tolerant in adverse conditions and facilitate quick assembly.
  • Fine thread series (UNF/UNRF) is commonly used in precision applications and in there where require a higher tensile strength than the coarse thread series.
  • 8 – Thread series (8UN) is the specified thread forming method for several ASTM standards including A193 B7, A193 B8/B8M, and A320. This series is mostly used for diameters one inch and above.

Hex Nuts

Hex nuts (dimensional data) are defined in ASME B18.2.2, and even as bolts the threading in ASME B1.1. Depending on a customer specification, nuts must be both sites chamfered or with on one side a washer-face.

Nuts

Dimensions of above mentioned nuts, can be found on page Heavy Hex Nuts of this website.
Note: the height of a nut for Stud Bolts are the same as the diameter of the thread rod.

Materials For Stud Bolts

Dimensions from Stud Bolts are defined in the ASME B16.5 standard. The material qualities for studs are defined in the different ASTM standards, and are indicated by Grade. Frequently used grades are A193 for thread rods and A194 for the nuts.

ASTM A193 covers alloy and stainless steel bolting material for pressure vessels, Valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications.
ASTM A194 covers a variety of carbon, alloy, and martensitic and austenitic stainless steel nuts. These nuts are intended for high-pressure or high-temperature service, or both.

Below you will find as an example a table with materials and grades for flanges, thread rods (bolts) and nuts, arranged on design temperature, flanges, thread rods and recommended nuts.

Marking Of Stud Bolts

Thread rods and nuts must be marked by the manufacturer with a unique identifier to identify the manufacturer or private label distributor, as appropriate. Below a number of ASTM examples.

Marking on Bolts

 

Method For Calculating Stud Bolt Lengths

The Stud Bolt Theoretical Length Can Be Calculated
By Means Of The Formula: L = 2 (S + N + H + Rf) + G

Drawing for calculation of Bolt Length

  • s = free threads (equals 1/3 time bolt diameter)
  • n = nut height (equals nominal bolt diameter)
  • h = flange (plate) thickness
  • rf = height of raised face
  • g = gasket thickness

PTFE FLUOROCARBON

  • (PTFE) a FluoroPolymer that is corrosive chemical and heat resistance, and the world’s most slippery surface.

DACROMET COATING

  • DACROMET 320 is a an aluminium-grey, non-electrolytic, thin coating for anti-rust protection of steel, cast iron and other ferrous metal parts.

HOT DIP GALVANISING

  • Batch hot-dip galvanizing has been the most commonly used method of protecting steel products from corrosion.

NICKEL PLATING

  • Nickel plating (Ni) is used for decoration and corrosion protection of steel, copper, aluminium and magnesium, for smoothing out surfaces.

COBALT PLATING

  • Cobalt plating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal.

CADMIUM PLATING

  • Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron.

Application

COMMON USES FOR NICKEL ALLOY FASTENERS INCLUDE:

  • Food processing or food serving equipment
  • Marine and saltwater equipment
  • Pump and valve components
  • Equipment and components exposed to chemicals, acids and other corrosive materials
  • Exhaust systems, engine components and other high heat equipment.

We use the following exotic alloys:

  • Titanium – Used for power generation, marine and military components that require high tensile strength to weight ratios, corrosion resistance and perform well in high wear and high temperature environments.  These include frames, landing gear, hydraulic equipment, propeller rigging and heat exchangers.
  • Zirconium – Used for components used in high corrosion environments, including nuclear power plants, and high temperature parts for engines and turbines.
  • Tantalum – Used for furnace and heat processing components due to its high melting point and oxidation resistance.  It is bioinert and is also used for medical implant components.
  • Ferralium – Used for chemical and process equipment and manufacturing equipment components that require high corrosion and high abrasion resistance.
