Flange and Valve wrapping tape system - Biggest Drawback

Flange and Valve wrapping by a tape system is a real bad idea.

1. This tape system needs a lot of preparation time.
2. Installation involves skilled labor from the manufacturer.
3. Once a Flange is sealed Maintenance cannot be done. - Biggest drawback.
4. Cannot be reused.
5. Too much work in form of removing the packing and tape -After a Flange leak
6. High cost associated in terms of preparation, supervision and material.
7. Installation for large number of flanges will take months.

Any solution that seals the flange and is not reusable is a failure. We need to understand that flanges joints are subject to failures :

1. Gasket failure - Mechanical deterioration with time, over tightening, temperature and 

2. Fastening system failure - Bolting is subject to vibrations,stress and fatigue.

3. Alignment-Improper alignment of both faces of flange often leads to a Flange failure.


Flange spray safety shields are the best solution for Flange joints. Reasons that support the case:
1. Less than 60 seconds to install
2. Reusable
3. No special manpower or supervision required.
4. No preparation is required on the flanges
5. Easy to remove will take 30 seconds to remove.
6. PTFE / SS316/HDPE most common Flange Guards.
7. Transparent Flange shield available for valves
8. Very reasonable cost 

INDANA Flange Guards are world renowned for its quality service and affordable flange spray shields.

What is the most commonly used material for nuts and bolts?

Be it construction or any other major industry the role of nuts and bolts and other types of fasteners are critical. Thus they determine the overall strength and structure of the largest structures. 

So in case you happen to have your business in the manufacturing or construction sector we are sure that you would be interested to know what the commonly used materials for nuts and bolts are. So let us understand the different types of materials used. The different types of fastener materials usedFasteners are made with   a wide variety of  of materials . These include everything from common steel to titanium, plastic and other exotic materials. Some of these materials are again separated into different grades. This is done to describe specific alloy mixtures, hardening as well as processes involved. 
Apart from this some nuts and bolts are available with a variety of coatings or platings. This is done to increase the resistance against corrosion or alter the appearance of the fastener.


Safety officer - It's Time to check your safety procedures

A safety officer ensures that policies and safety regulations are followed by his co-workers. His primary focus is to ensure safety of manpower at the manufacturing plant and containing incidents happening because of unsafe procedures and negligence.

In today’s times companies have started using UAV’s to keep a real time check on safety procedures. The monetary objective reduces the workers compensation by almost one third. The long term objective is improvement in workers morale resulting in better productivity and overall creating a safe environment.

A safety officer investigates incidents to prevent recurrence and ensures continuity of production. At times piping accidents have happened because the workers had inadequate knowledge about safety procedures and equipment’s. Safety gears can be divided in two categories the first being used by the worker himself like protective suits, helmets, glasses, safety shoes, appropriate hand gloves, gas masks and the second category being…

Choose stainless steel fasteners

The use of stainless steel fasteners is quite popular in many industries. The reasons include factors like they are corrosion resistant and also because they are recyclable. The other great benefit for using them is they offer any level of usage severity. 
They also have great capacities to bear load in both hot as well as cold weather. In spite of the many benefits the stainless steel fasteners have if these are not handled properly it could cause great damage to the entire set up. The following are certain mistakes you must avoid at all times:
Choosing the wrong grade
One thing which you ought to be careful about while choosing stainless steel factors is choosing the right grade of stainless steel fasteners. You must know that the grade 304 and 316 are the one which offer great resistance to corrosion. 
So this could be your preferred choice while choosing stainless steel fasteners. In case these are to be used in weather conditions which bring about rapid corrosion grade 316 is ideal.…
