According to the World Health Organization (WHO), particles less than 3μm in diameter and 5μm in length can be inhaled into the human body and are classified as disease-causing substances such as lung cancer, esophageal cancer, and mesothelioma. Based on the above criteria, the test request and test results are long fibers with a length of 5cm or more in the case of Hytrin, and the diameter is always 7μm or more, making it a material that cannot be inhaled by the human body making it safe.

The difference on the surface of HITLIN products is HGA TYPE when attached, and HG TYPE when it is not attached depending on the presence or absence of aluminum foil. There are 3 types of aluminum foil, 20㎛, 50㎛, and 70㎛. However, since it is a principle to use flame retardant products for surface bonding in the shipbuilding field, adhesives and flame retardant products are also used. In the case of nuclear power plants and shipbuilding, 50㎛ and 70㎛ are used, so it can be constructed without a special exterior material, and it has the advantage of preventing condensed moisture from penetrating into the insulation due to temperature differences.

HITLIN has the advantage of being reusable because there is no deformation of the material itself during repair and maintenance disassembly after construction, and we inform you that there were no performance issues among the projects that have been constructed so far.

HITLIN has domestic and overseas agencies. So for matters related to material purchase, please contact the regional agency or the head office sales development team and we will tell you the details.

In the case of the pipe cover, it is composed of 2 pieces, 1m long, up to the size of the pipe, up to 44″, so you can enjoy economic effects in terms of physical properties due to its simple construction. In addition, in the case of the ELBOW COVER, since it is molded and delivered to the correct standard, construction can be performed without the need for special work on site.

Since HITLIN is a product made of long glass fiber, which is a fiber structure, as raw material, it does not break or change shape due to external shock or vibration of the pipe. However, we have to inform you that the product is can be damaged by negligence in transportation which causes more losses than damages caused by impacts. due to negligence in transportation and management rather than damage to the material due to impacts.

The shipping cost for the product is based on the head office’s loading chart, and in the case of large quantities, it is delivered directly to the on-site arrival map (loading plan) using the transportation of our company, and in the case of purchases of small quantities, each cargo in the requested region is delivered through delivery companies.

It uses the principle of surface hardening or deep hardening within 30 seconds by covering the conventional HITLIN surface with a composite material (UV-GRP Sheet) that is hardened with ultraviolet rays instead of a thermosetting method.

By forming a radical of PI (Photo Initiator) under UV light, it forms a three-dimensional network through initiation, growth (propagation), and termination reactions between monomers and oligomers.

1. CUI piping corrosion prevention by preventing moisture penetration
2. Prevention of heat loss
3. Reduced plant construction time and construction cost due to replacement of tin
4. Internal and external corrosion, chemical resistance, and mechanical strength increase
