Threaded Rods

by on Jun.10, 2010, under Fasteners

Threaded rods are metallic bars that are threaded to accept nuts and washers in various standard sizes. They are mostly used in any application where two pieces of material need to be fastened to each other. In other words, one or both ends of the threaded rod are inserted into pre-threaded holes, or in the same manner, bolts can be threaded onto either or both ends to draw the separate pieces of material together. These threaded rods are made of various materials and come in various sizes and finishes.

Pipe Clamps

by on Jun.10, 2010, under Clamps, Pipe Fasteners

The pipe clamps are special type of fasteners suitable for clamping pipes, hoses and electric cables. Pipe clamps are a sensible and easy way of securing piping, tubes and hoses in all types of terrestrial or naval installation. They are designed for use in water/plumbing purposes. They are also used for mounting of pipes to the walls. Some pipe clamps can also be mounted on piping components other than straight pipe. There are also heavy-duty structural pipe clamps designed for use with standard size water/plumbing pipe that is not threaded. Many pipe clamps have solid cores for added strength. The pipe clamps are sometimes controlled by pressure activated cylinders to regulate the clamping pressure in relationship to the thickness and strength of the pipe wall.

Buying Tips

Pipe clamps can be ordered as complete arrangements or separate components. Certain factors to consider to buy pipe clamps are as follows:

  • Type of clamp
  • Size
  • Material
  • Finish
  • Durability
  • Mechanical Properties

    • Tensile Strength
    • Flexural Yield Strength
    • Impact Strength
    • Tensile Test
    • Thickness
    • Modules of Elasticity
  • Thermal Properties

    • Continuous Service
    • Temperature Range
  • Electrical Properties

    • Volume Resistivity
  • Chemical Properties

Pipe clamps usually have one fixed pad, and one adjustable pad. Pipe clamps are constructed using various materials and are available in several configurations with a variety of finishes. Metallic pipe clamps have high impact resistance and various finishes like a brilliant, glossy finish, heat-resistant coatings and epoxy coatings or plain look or hot-dip galvanized or painted.

Materials used:
Various materials used are as follows:
  • Carbon steel
  • Mild steel
  • Stainless steel
  • Alloy steel
  • Titanium
  • Aluminum
  • Thermoplastic elastomer
  • Polypropylene
  • Polyamide
  • PVC etc.
Types of Pipe Clamps:
Various types of pipe clamps are as follows:
  • Rigid Clamps
  • U-Bolt Clamps
  • Flat Cushion Clamps
  • Oval Clamps
  • U-Bolt with Cushion Clamps
  • P Style Clamps
  • Swivel Bolt Clamps
How to measure pipe clamps?
Take the measurements of the following:
  • Diameter
  • Outside diameter of pipe
  • Cap nut diameter
  • Load ability
Features of Pipe Clamps:
Common features of pipe clamps are as follows:
  • Simple to operate
  • Easy to install
  • Adjustable in small range
  • Good appearance
  • Temperature range is dependent on the clamp lining being used.
  • All pipe clamps are designed to have a very high impact resistance.
  • Make for quick, easy pipe installation and layout.
  • Shock-absorption
  • Vibration dampening
  • Noise reducing property
  • Heavy torque
  • Usually used for large diameter pipes etc.
Mounting Guidelines of pipe clamps:
  • The clamp should be mounted directly after the threaded connection or coupling of the piping which in turn protects the connection from vibrations.
  • Bends in the line should be clamped on both sides of the pipe bend.
  • The pipe line should be clamped directly before and after any in-line valves.
  • Proper Torquing of the clamp bolts is very essential.

    Uses of pipe clamps:

    Some uses of pipe clamps are as follows:
    • Used for fastening and fixing various pipelines whether in construction or industries or buildings etc.
    • Provide fast, safe, economic service and installation in piping system.
    • Pipe clamps are designed for a wide range of fastening applications.
    • These clamps are ideal for suspension of cold or hot pipe lines with heavy load having little or no insulation.
    • They are also used for high and even tightening force around the pipe, minimizes leakage.
    • The pipe clamps absorb shock, dampen vibration, and reduce noise in plumbing systems.
    • They can be used in high temperature applications.
    Applications of pipe clamps:
    Pipe clamps are used in general industrial pipe construction, in all areas of residential, industrial, mobile and marine hydraulics, the field of press technology, instrumentation and control technology, and many other application fields.

    Eye Bolts

    by on Jun.10, 2010, under Eye Bolts, Fasteners

    Eye bolts are special purpose bolts which are threaded with a loop or eye at one end. These type of bolts are used where external tension loads are to be applied. The eye of the bolt is used to anchor a cable, chain or rope . Eye bolts are used in different types of applications and they can pivot or swivel. They are available in various sizes and are made of various materials. They are provided either plain finish or hot dip galvanized. They are used in wide number of applications, including pipe fittings.

    Buying tips

    Certain specifications to consider before buying eye bolts are as follows:

    • Maximum load capacity: The maximum load which an eyebolt can handle.
    • Shank length: Shank length equals the thread length, for fully-threaded eyebolts.
    • Threaded length: Thread lengths for eyebolts are measured in English units like in inches (in) or metric units such as millimeters (mm).
    • Eye inside diameter (ID)
    • Eye thickness or Eye section diameter
    • Total weight
    • Material
    Materials used:
    • Copper
    • Cast Iron
    • Aluminum
    • Brass
    • Bronze
    • Stainless steel
    • Alloy
    • Titanium
    • Plastic
    • Rubber etc.
    How to measure eye bolts?
    Take the measurements of L, T, D, C. For dimensions, measure D×L×T×C.


    Types of Eye Bolts:
    There are four types of eyebolts. They are as follows:
    • Forged eyebolts: These eyebolts are forged instead of formed. They are one-piece fasteners offering higher load ratings.
    • Shoulder eyebolts: These eyebolts have a shoulder under the eye and the shoulder is installed flush with the mounting surface.
    • Thimble eyebolts: These eyebolts are designed with an opening that acts as a thimble for rope or wire to minimize wear.
    • Pivoting eyebolts: These eyebolts are designed in such a way to pivot 180°.
