Pigging is a very special process. You need to talk to the companies specialized in this discipline. TDW specializes in this area. You may contact them, for specific services in Bangladesh, if they provide so. I know they've a big presence in India. This presentation discusses with some interesting issues, related to pigging .

Hope it will help you.

 

Thanks.

Subject: [MW:32751] Selection of Pigs For 30" Gas Pipeline

 

Dear Experts,

 

Hope everyone is doing great.

 

In a cross-country gas pipeline project over a bridge deck we have almost completed ou welding activities and right now we are facing problem in selection of Pigs for that pipeline. For your information, the pipeline is about approximately 6 Km in length consisting of 14 nos U-loop and 06 Nos W-loop and 01 nos inlet and 01 nos outlet loops. Outer Dia of Pipeline is about 762 mm with a wall thickness of 25.4 mm.

 

The elbows in the loops are 1.5D 90 Degree LR BW elbows.

 

The entire pipeline has some pipe miter joints included but the angle of miter falls between the range of 2.5 Degree to  5 Degree.

 

 The normal pigs we use for our cross-country pipeline having 3D & 5D Bends are not suitable here.

 

As I have limited knowledge on pigging, hope some expert comment can help me to select the appropriate pig and finalize procurement for my project in Bangladesh.

 

 

With best regards,

Asif

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
