Accommodates small changes in line direction without fittings or differential settlement

Flexible manufacturing

•Custom diameters can be process manufactured to provide maximum flow volumes with ease of installation for rehabilitation

lining projects

High technology pipe design

•Lower wave celerity than other piping materials can mean less cost when designing for surge and water hammer pressures

High technology pipe manufacturing system producing pipe that complies to stringent performance standards (AWWA, ASTM, DIN, EN, etc.)

•High and consistent product quality worldwide which ensures reliable product performance

Control Testing of GRP FRP Equal Tees Sea Water Pipe Series

Raw Materials

Raw materials are delivered with vendor certification demonstrating their compliance with Zhongfu Lianzhong quality requirements. In addition, all raw materials are sample tested prior to their use. These tests ensure that the pipe materials comply with the specifications as stated

Physical Properties

The manufactured pipe’s hoop and axial load capacities are verified on a routine basis. In addition, pipe construction and composition are confirmed.

Finished Pipe

All pipes are subjected to the following control checks:

• Visual inspection

• Barcol hardness

• Wall thickness

• Section length

• Diameter

• Hydrostatic leak tightness test to 1.5 rated pressure (only PN6 and above)

On a sampling basis, the following control checks are performed:

Pipe stiffness

Deflection without damage or structural failure

Axial and circumferential tensile load capacity

UnloadingHandlingTransportation and Storage of GRP FRP Equal Tees Sea Water Pipe Series

Unloading the pipe is the responsibility of the customer. Be sure to maintain control of the pipe during unloading. Guide ropes attached to pipes or packages will enable easy manual control when lifting and handling. Do not drop, impact, or bump the pipe, particularly at pipe ends.

If at any time during handling or installation of the pipe, any damage such as a gouge, crack or facture occurs, the pipe should be repaired before the section is installed.

Transporting Pipes

Strap pipe to the vehicle over the support points using pliable straps or rope. Never use steel cables or chains without adequate padding to protect the pipe from abrasion. Bulges, flat areas or other abrupt changes of curvature are not permitted. Transport of pipes outside of these limitations may result in damage to the pipes.

Site Pipe Storage

It is generally advantageous to store pipe on flat timber to facilitate placement and removal of lifting slings

around the pipe.

When storing pipe directly on the ground, be sure that the area is relatively flat and free of rocks and other

potentially damaging debris. Placing the pipe on mounds of backfill material has been found to be an effective

way of site storing the pipe. All pipes should be chocked to prevent rolling in high winds.

FAQ of GRP FRP Equal Tees Sea Water Pipe Series

Q1: What’s the performance standards?

Lianzhong pipe is designed to meet all of these ASTM , AWWA, BS, DIN standards.

Q2: What’s the qualification testing for the products?

 Lianzhong pipe has been rigorously tested to verify conformance to the ASTM D3262, ASTM D3517, AWWA C950 and DIN 16868 requirements

Q3: How long can I receive my goods?

A: Usually, we will deliver products within 20 days after the contract is signed. Delivery time is negotiable when necessary.




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: The difference between FRP process tubes and GRP tubes
Pure glass fiber reinforced plastic pipe relative to sand pipe prices higher, in addition, the two types of pipe applications in general have obvious differences, process tubes are used in chemical plants and other places, sand pipes are used in municipal.
Q: Why FRP pipe corrosion?
If it is ordinary water, generally does not count corrosion, there will be no obvious corrosion, long time began to soak rotten.
Q: Mending method for glass fiber reinforced plastic pipe
The method for mending and mending the glass fiber reinforced plastic pipe is hand paste, and the repairing steps are as follows:The stones must be taken away so that the pipes are restored to their original shape.Into the pipe, grinding first and lining the lining. If you can't get into the pipe, polish it from the outside, polish it to the lining, and then make a new lining.Reinforce the structure with a cloth.
Q: Galvanized steel sheet and inorganic glass fibre reinforced plastic pipe are calculated according to this norm or norm
According to the project of quota valuation mode, input the actual quantity according to the quota item number, the following materials will automatically adjust the quota quota project, has been considering material wastage, when engineering calculation does not need additional.
Q: How to open a DN300 port on the DN600 GRP pipe and install the DN300 gate?!
Do not know the road of glass steel flange have, if any to buy different materials of cast iron flanges or PVCU flange on the same material, the three way behind the pipeline branch, so that the material market has purchased (ABS buy buy in the small town is not easy), the construction is convenient. If it is a glass steel pipe, pipe end cannot change, can only be used to bond the glass steel material, the pipe bonded on the flange is an arc for a plane is bonded with a cast iron pipe flange suggestions. Because the FRP material and most of the plastic are not bonded.
Q: What is the standard of flange coefficient for FRP ducts?
That quota said: glass steel duct, pipe fittings, flange and reinforcing frame are in accordance with the finished preparation, only the wind pipe and the valve flange connection, before the implementation of the equipment support within the 20kg section, multiplied by the coefficient 1.4. Glass fiber reinforced plastic wind pipe is finished product: when it is made, there are moulds. According to the design of the drawing, the mould is made. The flange and the air duct are one! Remove the mold and install the hole on the flange! In general negotiations with the manufacturers directly n yuan / square meter (production, installation), whether it involves the number of flanges, such as included, there is no need to re count, direct calculation of the inner diameter of the air duct is the expansion area!
Q: The role of glass fiber reinforced plastic cooling towers
Central air conditioning also has cooling tower function is to play the role of cooling circulation.
Q: What are the advantages of FRP pipes?
Light weight, corrosion resistance, aging resistance, long service life,
Q: How many times can the temperature withstand of FRP winding pipes? What are the factors?!
The temperature of FRP winding pipe is greater than -70 degrees Celsius, less than 250 degrees celsius.
