Two Heat-isolation Pipes are Occupying Market

When we talk about heat-isolation pipes, there are 2 heat-isolation pipes that we can’t ignore -- the rock wool pipe and the Silicate aluminium extrusion.

The rock wool pipe

With the increasing needs for the pipeline of many industries and some important areas, the pipeline industry advanced much now. So, to a certain extent, in order to meet the needs of the market better, it is necessary to go on a road of diversification of pipe production. So now, there are many products with excellent performance on the market, and the rock wool pipe is one of them. Rock wool pipe is economic and durable, inexpensive as well.

Then, what are the important advantages of the rock wool pipe?

First of all, its row material is strictly selected, and it takes the melting processing technology to make it better physical properties..

At the same time, it also meets well with the current market demands which have a high requirement on the insulation material. Through a unique processing technology, it is effective not only in the insulation and insulation, but also in the sound absorption.

Silicate aluminum pipe -- Silicate aluminum needled blanket

Silicate aluminum needled blanket is made of high quality coke gems which solidify with other additives fusion after melting through high temperature of more than 2000 degrees Celsius. It has a number of special properties, such as good elongation, strong vibration resistance, light weight, excellent heat insulation, and strong stability. Silicate aluminum needled blanket is white, and size standardized, and is able to resistant to fire and heat, without adding any other bonding agent. In the neutral and oxidative condition for long-term, silicate aluminum needled blanket can still maintain the outstanding tensile strength, durability and fiber structure. The temperature of heat resistance is 950-1400 ℃. It also has advantages of chemical stability, thermal stability, sound and noise reduction, high tensile strength, low thermal conductivity and low heat capacity.

Silicate aluminum needled blanket should take the 20 or 25mm thick ceramic fiber needle blanket and fold it to process into the specified size, and only the folding wrinkle surface is a high temperature heating surface. The module should be temporarily tightened to the specified size so as to maintain the amount of compression, its size and shape of the ceramic module before installation. The permanent metal anchors in the MA and MB modules shall be confined within the area in one third of thickness of the module's low temperature end and should be embedded in a sufficient blanket to ensure that the module is structurally stable under various using conditions.

Then, what are differences between the 2 pipes?

The rock wool pipe belongs to a medium-heat isolation material, usually lower than 600℃; the silicate aluminum belongs to a high-heat isolation material, usually in between 400℃-1000℃.

(High temperature adhesive is the auxiliary product of all insulation materials, such as silicate aluminum fiber products, rock wool pipe, mineral wool material, and microporous calcium silicate insulation. It is not only used in self-bonding and connection with the steel pipe and metal flat for refractory and insulation materials but also used in the masonry for refractory bricks, foam bricks. )
