GRP Pipes Manufacturers

Marking, handling and transportation of products by GRP pipes manufacturers


Companies manufacturing GRP pipes and FRP pipes perform several tests to ensure quality of their products. GRP pipes manufacturers conduct a list of tests to extract the best quality piping for market users. How do they perform handling, marking, and transportation of these products once testing is done? In this post, we will discuss about these operations that manufacturers perform after testing the lots of pipes and products.


Both the ends of pipe length and fitting should be marked with letters not less than 12mm in height and bold font should be used in a color and type that remains legible under installation process and normal handling. There are certain things that marking should include-

  • Internal diameter
  • Pipe class
  • Manufacture date
  • Name of the manufacturer or his registered trademark or both
  • Nominal thickness

It is important for manufacturer to achieve ISI marking on their piping and fittings.


Suppliers and manufacturing units are also responsible for safe delivery of piping and fittings as per order place according to the schedule. If the piping and fittings are outsourced to the contractor, supplier should provide him a complete manual of instruction or guide for handling of pipe prior installation.

Fire safety:

GRP pipes are manufactured with a resin and petrochemicals, which are inflammable. So, supplier, manufacturer, contractor or any of them should take utmost precaution while handling, storing, transporting, unloading/loading, installing, testing, etc. in all phases, against fire. It is their duty to take proper care and avoid exposure of pipe to welder’s spark, cutting-torch flames, or other heat or electrical sources that could promote fire in pipe material.


Suppliers should provide flat timber support to all pipe sections on a maximum of 4m centers with a maximum overhead of 2m in trucks. They should check that no pipe should come in contact with other pipes during transportation.


Pipes should be stored on ground or on flat timbers. It is must for manufacturers to choke all pipes to prevent rolling.

Lubricant of gasket should be carefully stored to avoid any damage to the container.

This is it. This is how GRP pipes manufacturers handle, transport, mark, and store their products. If you want to know more about GRP products and piping solutions, connect to manufacturers and suppliers today. Share your reviews in comments with us and tell the readers how you find this article.

GRP Pipes

Understanding How The GRP Pipes Manufacturers Make The Pipes

GRP pipes are technically known as Glass Reinforced Plastic Pipes and they are the most important part of the composite engineering materials and their utility is good in a spectrum of applications with specific reference to the requirements pertaining to fluid transportation respectively.

GRP pipes manufacturers India have been manufacturing exclusive range of GRP pipes with eminent property combinations that are unavailable in the other contemporary materials used for engineering purposes.

GRP pipes manufacturers

GRP pipes manufacturers have progressed fast in their respective genres, for the materials they deal with are of high demand in the engineering arena and moreover, the GRP pipes are extremely durable as they are by default great at strength, weight ratio and also have high resistance to corrosion. These pipes demand not much maintenance, they are lighter in weight and so are easy to transport and install. They perform with zero scope for any flaws as they are designed with excellent flexibility and workability.

Most engineering processes prefer to use GRP piping in high pressure zones and harsh environmental conditions, considering the properties these pipes come with for excellent durability.

GRP pipe manufacturers follow certain procedures for eminent pipe manufacturing and below are some points about the same.

The GRP pipes manufacturing process involves three basic methods of which the first is the Filament Winding Method which is carried out in two different ways.

While one way is the continuous method, the other is the discontinuous method.

The second type of pipe manufacturing method is the Hand Lay-up Method while the third method is the Centrifugally Casting method.

Indian houses numerous standard GRP pipe manufacturers and various projects be it government, commercial or private project dealers consider contacting the Indian manufacturers, keeping in mind the quality and reliability their products come with.

While the engineering applications are mainly dealt with the GRP material, the industries that have more requirements of the materials are the automotive industry where the bumpers and bodies of automotives are built with the GRP plastic, the aerospace sector uses this plastic to build the panels and tail units of the aircrafts, water-related projects which require this plastic for the making of pipes, tanks and manholes; the chemical industry, the wind sector uses this plastic in the making of turbines and the electrical as well as sports equipment sectors also use this plastic in the making of their essentials.

GRP pipes are the best for engineering applications as they are:

  • Excellent at strength
  • No scope for corrosion
  • No chance of damage
  • Highly resistant to extreme environmental or weather conditions like heat, moisture, dryness or fire.
  • Light in weight
  • Easy to transport
  • Easy to install
  • Need no maintenance
  • Very minimal scope for repairs or damages
  • Reasonable at cost
  • Easily available in local regions
  • Made out of high standard materials so are qualitative

Most of the Indian manufacturers also manufacture customized GRP pipes in accordance with the client requirements and they work on project basis which is easy and mutually beneficial.
