We are constantly surrounded by unwanted sound (noise).

Today, clinical studies have proven that people exposed to high noise levels will face increased risk of cardiac diseases and their general stress threshold is significantly lowered. Fatigue, which can be seen in industry, at sea and offshore, is a serious safety issue for a large range of operators.

ROCKWOOL stone wool has an open fibre structure, which is ideal for the absorption and regulation of sound.

ROCKWOOL Technical Insulation can provide a full range of products and solutions to reduce the noise levels of technical installations. The nature and effect of the sound insulation depend on the frequency and the sound pressure level.

Our experts listened to process industry safety concerns:

“How to minimize noise emitting from industrial pipework...“ ...in a simple and efficient way?

What are the causes of industrial noise?

ISO 15665 is the standard that is widely accepted in the industry for designing the acoustic insulation of pipes valves and flanges

Noise can be generated by plant, equipment or the processing of fluids and/or gasses.

It can originate from the following:

Flow induced turbulence

Cavitation and flashing

Pumps and compressors

Pressure fluctuations

Valves or other pressure reducing devices

Change of pipe diameter

ISO 15665 sets out classes for acoustic pipework insulation systems. Insulation systems are classified by their insertion loss performance and the diameter of pipe onto which they are applied.

ISO 15665 is valid for pipes up to 1000 mm in diameter. It defines classes depending upon the diameter and the wall thickness of the pipe. It is not applicable to the acoustic in-sulation of rectangular ducting and vessels or machinery.

Class Diameter (ø) Min. wall thickness

1 ø < 300 mm 4.2 mm

2 300 mm < ø < 600 mm 6.3 mm

3 ø > 600 mm 6.3 mm

The standard allows noise control engineers to select the correct insulation system during the design stage in order to ensure that specified noise targets are met.

ISO 15665 is largely adopted by the major operators in oil and gas business.

Similar requirements are laid down in NORSOK standard R-004 class 6,7 & 8, CINI 9.2.02 and ASTM E 1222.

ProRox acoustic solutions with Pipe sectionsProRox PS 960 is a pre-formed stone wool pipe section. The sections are supplied split and hinged for easy snap-on as-sembly. Depending upon the acoustic demands, this solution can be equipped with an additional heavy mass layer and/or a waterproof insulation protection, ProRox GRP 1000.
