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:What kind of material are the flanges and valves on the GRP pipe?
It's better to use plastic or polyurethane
Q:What are the materials used in smoke exhaust pipes?
Different uses of flue gas pipes are also made of different materials. Refer to
Q:How to install FRP pipe correctly
And glass fiber reinforced plastic parts (three, elbow, etc.) in general, the best way is on-site bonding, quality stability and convenience.
Q:What are the main materials used for steel pipes?
The grade of the material according to the general use of distinction: 1, clean air conditioning system with wind pipe: galvanized plate, stainless steel (disabled; glass steel, composite dust pollution may be used in the wind pipe with 2), the central air conditioning system: galvanized plate, color steel insulation board; (can use glass steel, the composite wind pipe) in 3, the environmental control system: galvanized steel plate, stainless steel; (can use plastic, glass steel, composite materials) duct 4, industrial ventilation system: steel plate, galvanized plate; (can use plastic, glass steel, composite materials) Note: can be divided into two kinds of organic and inorganic glass steel duct, according to the design specification has disabled organic material fire safety requirements; air duct 5, special occasions: glue cloth hairdryer, mine plastic mine ventilation pipe; (flame retardant and anti-static characteristics of mine safety requirements)
Q:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?
Glass tube wall thickness is generally determined by the manufacturer design, with stereotypes products and sequences, you can choose according to the pressure level.
Q:What's the process of continuous winding glass fiber reinforced plastic sand pipe?
(1) die: the continuous flat steel supported by the reel, winding to form a round mandrel.(2) feeding: when the mandrel moves, advanced packing, glass fiber, resin and surface material are accurately placed under the control of program control (PLC) and microcomputer (PC).(3) monitoring: according to the prepared material input program, only the basic pipeline data can be input; the computer can calculate the mechanical operation settings by itself. Material consumption, pipe thickness and so on will be constantly monitored and recorded.(4) curing: induction heating of the curing process of the product is accomplished by the flat band and the infrared device which is directly heated in the product. The temperature of 20 different parts of the product in the curing zone will be measured and displayed in the form of an image on the computer screen.(5) cutting and trimming: the pipe can be cut from 0.3 meters to 18 meters under the predetermined length. The cutting, chamfering and caliber measurement are coordinated with the longitudinal movement of the product to ensure the accurate vertical cutting of the glass fibre reinforced plastic pipe and the killing of the outer diameter.
Q:CGCT what's the meaning of the GRP sand pipe?
The pipeline in the design according to the use of pressure, stiffness and other conditions to determine the need for sand, if the thickness of the pipe can satisfy the pressure requirements and can meet the requirement of stiffness, is generally not the sand.
Q:What kind of project needs fiberglass pipe?
Glass fiber reinforced plastic products are characterized by corrosion protection, high temperature resistance, humidity resistance, alkali resistance, etc., where it is necessary to use the glass fiber reinforced plastic pipe!!
Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
1) first, apply the release agent on the molding surface of the glass lined sand pipe mold (or a transparent cellophane on the outer surface of the mold);2) after sufficient drying, the magnesium oxychloride cement with initiator (or curing agent), accelerant and other additives is evenly coated on the molding surface of the die;3) then put a good glass cloth on the glass lined sand pipe;4) then apply the magnesium oxychloride cement on the paved glass cloth and take care to remove the bubbles.5) with good magnesium oxychloride cement paste then with cut glass cloth;6) repeat this operation until the GRP sand pipe reaches the design and gauge thickness.
Q:What is the stiffness of FRP pipe?
Stiffness, also called ring stiffness, is a numerical indicator of actual resistance to external pressure. Ring stiffness S definition: S =EI /D 3 (where E is the elastic modulus of the material, I is the moment of inertia, D is the average diameter of the pipe ring), and the ring stiffness is KN/m2.
