Product Description:

Introduction of GRE Pipes for Oil Exploration and Transportation

Lightweight and easy to handle and install, GRE pipes have a smooth internal surface that reduces friction and enables a high pipe flow capacity. The low thermal conductivity of GRE pipes relative to steel (only one percent of steel values) minimises the cost of insulation and heat loss. Another major benefit of GRE pipes is that, once they are installed, they are virtually maintenance-free.
GRE pipes are well suited for environments where corrosion resistance is required at a reasonable price.
Main uses include petrochemical process lines, oil and gas systems, fire-fighting systems, offshore and onshore systems, and ship and marine applications.
GRE pipes are available in diameters ranging from DN 25 to DN 1,000 mm.

FAQ:

1, Connection of the GRE Pipes:

API screw thread seal with aquaseal connection of 8 round or 10 round;

 

2, Standard of the GRE Pipes?

API Spec 15HR

 

3, Fittings supplied?

All of the standard GRE fittings are matched well with the original pipes. Most of the fittings are produced by filament winding process.all fittings should be ordered as per thread specification and design pressure.

Q:Are FRP pipes still developing?
I graduated last year and like you, stay two months left, glass steel pipeline buried pipe still have comparative advantages, but in Chinese, the quality of the products before this, after all, as the steel pipe is reliable, now doing chemical, water treatment, rarely encountered glass steel pipes, steel pipes generally do not. PVC, most used, the cost is much lower than the glass steel
Q:What are the materials used in smoke exhaust pipes?
According to the current national standards: ventilation pipe exhaust pipe material selection of steel pipe (steel), galvanized plate (Bai Tie) smoke pipe, the exhaust pipe exhaust pipe, exhaust pipe, stainless steel pipe, plastic glass smoke exhaust pipe, composite sandwich insulation board, industrial exhaust pipe exhaust exhaust pipe.
Q:Would like to ask about the plastic lined steel pipe, steel pipe, glass steel skeleton, the advantages and disadvantages of each ceramic pipe, to know a friend told, very grateful!
Plastic lined steel pipe of strong corrosion resistance, heavy quality, need to be made, on-site installation, if the size deviation cannot be installed. The price is more than 5 times more expensive than that of FRP
Q:What are FRP pipes made of?
Length of single pipe lengthReduce pipe connection, speed up installation, improve the quality of the whole pipeline.
Q:What is the thickness of all types of FRP pipes?
The standard effective length of the tube is 6m and 12M, and the production methods include fixed length winding process, centrifugal casting process and continuous winding process of three kinds. Classification can be carried out according to the product process method, pressure grade PN and stiffness grade SN.
Q:What are FRP pipes used for making? What raw materials?
Reinforced plastic made of glass fiber or its products as reinforcing material. Entitled "glass fiber reinforced plastics" or "glass fiber reinforced plastics". Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. Glass has a hard and brittle, has a good transparency and high temperature resistance, corrosion resistance and other properties; at the same time, steel is very hard and not brittle, but also has high temperature resistance characteristics.
Q:Do I need CCC certification for ventilated GRP?
Of course, there is also used for air conditioning duct glass fiber reinforced plastic pipe, the thickness needs at least 25MM, lined with EPS insulation foam.
Q:A basic overview of FRP pipes
FRP pipes are made of resin (feed water, food grade resin), glass fiber and quartz sand as raw materials and made by special process.
Q:How to improve the compressive strength of waste glass fiber reinforced plastic profiles (such as square tubes) should be started with resin, curing agent, glass fiber or other aspects!
Using reinforced materials of good quality, reinforced materials without alkali glass fiber are used;
Q:Glass tube has different diameters with different prices. Who can elaborate?
According to the standard requirements, DN25-DN2500 pipes can be produced. The pressure levels are gravity flow, 0.6MPa, 1.0MPa, 1.6MPa
