Unit Weight of Oil Products

 Dear Readers,

Oil products are measured both in kilograms (kg) and in Liters (L). Calculating weight from volume units of oil products are as follows.

1. LPG: 1 liter = 0.53 kilogram.

2. Naphtha: 1 liter = 0.75 kilogram.

3. Oil-aromatics: 1 liter = 0.75 kilogram.

4. Aviation fuel: 1 litre = 0.80 kilogram.

5. Motor fuel: 1 litre = 0.745 kilogram.

6. Other light oils: 1 litre = 0.75 kilogram.

7. Petroleum: 1 litre = 0.79 kilogram.

8. Gas, diesel, light fuel oil: 1 litre = 0.84 kilogram.

9. Heavy fuel oil: 1 litre = 0.96 kilogram.

10. Lubricants: 1 litre = 0.88 kilogram.

The standard unit of measurement for oil weight is API Gravity. This scale was created by the American Petroleum Institute to measure the density of oil.

 

It shall be summarized as follows.

The higher the API, the lighter the oil.

The lower the API, the heavier the oil.

Unit Weight of Parallel Flanged Channel

Parallel flange channels are more commonly known as PFC or C-section. A PFC is a vital part of the structural steels used in the construction of buildings and large-scale steel fabrications. 

The Parallel Flange Channel is praised for its ability to provide increased strength and durability to steel projects. Typically used as columns or as support for floor joists and have a highly desirable load bearing profile. You may also find PFCs used in conjunction with RSJ steel beams, universal columns and all forms of structural steel.

Unit Weight of M.S. Sheets

Dear Readers,

We are very often use the sheets and plates during construction activities. Sheet metal and plate metal are different forms of steel. The most notable difference between plate and sheet metal is the thickness of the products. Plate metal is thicker when compared to sheet metal.

In general thickness less then 5.99 mm is called sheet and more than 6 mm is called plates. Sheets can be measured in SWG or in mm (millimeter). Unit weight of Sheets is as follows.

Sheet metal is produced on an industrial scale by applying rolling, processing and drying techniques. Eventually it is the process of rolling that will decide whether a particular metal will be classified as sheet or plate. Rolling metal adds pressure which determines the overall thickness of the metal. If the metal is rolled thin then it is considered to be sheet and if it is thick then the metal can be classified as plate.

Weight of Pipes

 Dear Readers,

In continuation with my earlier post " Difference between Pipes & Tubes" , let us note the unit weight of Pipes, wall thickness and further details.

Pipes are specified based on the schedules. Normally we mention pipes as Standard pipes, Extra Strong, Double extra strong based on the applications and utilization purpose. However further it also classified technically on Schedules, subject to the wall thickness , These schedules starts from Schedule-10, Schedule-20, Schedule- 30 , Schedule-40, Schedule-60, Schedule-80, Schedule-100, Schedule-120, Schedule-140 & Schedule-160

Below Table shows the weights of Standard pipes, Extra Strong & Double strong. Theses are readily available in market.

Unit Weight of Hex Bolt and Nut

 A bolt contains two parts a shank and head. The cylindrical portion of the bolt is known as the shank. The shank is threaded at the tail end for a sufficient length so as to effectively engage with a nut.

The shape of the head is depended upon the purpose for which bolt is required. The nut is a type of a fastener which has a threaded hole in it. The nut is always used in joining with a mating bolt to fasten various parts together.

Bolts and nuts can be made of various materials such as steel, titanium or plastic. The finish or plating on a metal bolt or nut affects its look and durability. Below are some common finishes and benefits:

• Zinc - Most common, low cost, resists corrosion and rust

• Nickel - Very hard finish, higher investment, good corrosion resistance

• Chromium – Bright finish, good rust and corrosion resistance

• Chromate – Adds color, shine, superior rust resistance

• Anodizing - Aluminum, hard oxide surface, excellent corrosion resistance

Generally purchasing of fasteners are in Kilograms instead of pieces. But we could not know how many numbers available per Kg. For construction purpose, Bulk purchase is advisable. Hence below count table will be useable. Counts are based on 50Kg

Tapered Flange Beam

Tapered Flange Beam is also known as I-beams, as the name states are manufactured in the shape of a capital "I". The vertical middle section of the beam is known as the 'web' and the horizontal components are called 'flanges'. The vertical “web” of a beam is significantly longer than horizontal “flange”.

 The core of the I-beam, better known as the web, will ensure that resistance against shear forces is provided. Except for the web, the I-beam also consist of flanges, taper or parallel flange, on either side of the web and at both ends. The flanges provide resistance to bending moments.

Please see below the dimensions and weights for the taper flange I-beam.

Tapered Flange Beams are commonly used in residential and non-Residential Construction. In the construction industry I-beams are used as cross sections providing strength to girders, it also provides support to joists which in turn support ceilings and/or floors. They are also widely used in the construction industry as a support for buildings to ensure that the structure is strong enough. Even though I-beams can resist bending, it should preferably not be used in cases where torque forces are present along the axis or length of the beam as they are not torsion resistant.

Deposition of Welding Electrode

Dear Readers,

During Fabrication and Erection works we used welding electrodes for welding process. This article let us discuss about the weld metal deposition calculation.

Welding Electrodes available in markets are 2.5 mm, 3.15 mm, 4 mm & 5 mm with a length of 350 mm or 450 mm. The size mentioned 2.5 / 3.15 / 4 & 5 mm are only core material i.e excluding coating material. The length mentioned is full length including stub.

For calculation of welding deposition per rod we should know the effective length of Electrode usage. Note that Electrode 100% can not be consumed due to space between welding holder with work piece. Generally 75-100 mm of electrode will not be used depends upon the nature of work. Unused welding electrode including stub length. Industrial practice we used to call it is cut bits. It is shown in below picture.

For calculation purpose of welding deposition per rod we should know the effective length of welding electrode usage.

Effective Length = Length of Electrode - (Stub length + Unused electrode)

Following table shows the welding electrode deposition per rod in grams and number of rod required per kg weld deposition

Above table is calculated based on formula of cylindrical (Volume of Cylinder = Pi X r X r X h) and cut bit is 75 mm. Where "r" is radius of electrode and "h" is length of rod considered as a height

Percentage of efficiency will vary based on type of electrode. For CS Electrode is 100%, If it is Low Hydrogen AS electrode is 108% and If it is  Low Hydrogen CS electrode is 115%. This is due to flux coating material.
