Control Testing of GRP pipe 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

1. Internal liner (thickness 1.0 – 2.0 mm)
In tables bellow thickness include 1.5mm of liner and minimum pipe Stiffness 1250 Pa
2. Mechanical resistant layer in glass filament winding (based on internal pressure)
3. Top coat (0.2 – 0.3mm) . In tables bellow thickness include 0.2mm of top coat
Unloading,Handling,Transportation and Storage of GRP pipe sea water pipe series
Unloading and Handling Pipes
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 pipe 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:Are there any differences between FRP pipes and FRP pipes?
- Air duct is a pipe system used for air transportation and distribution. There are two kinds of composite air duct and inorganic air duct. The duct can be classified according to the shape and material of the section. Duct made of stainless steel duct, in the bite mouth, rivet joint, flange, four corners and other cracks painted with sealant (such as neutral glass glue). Surface dust and grease shall be removed before applying sealant. According to the section shape, the wind pipe can be divided into circular duct, rectangular duct, a variety of flat air pipe, wherein the circular duct resistance minimum maximum height, making complex. Therefore, the application of rectangular wind tube based. According to the material, the air duct can be divided into metal wind pipe, composite air pipe and macromolecule air pipe.
- Q:How is FRP ventilation pipe made?
- It should be noted that the flange and the duct shall be a whole and shall be at right angles to the axis of the wind pipe. The flanges of the air duct and its pipe end shall be formed together during the coating process. Glass fibre reinforced plastic pipe flanges shall conform to the provisions of table 5-21.
- 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: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:What are the standards for FRP pipes?
- In order to comprehensively check the installation quality of the pipeline, it is necessary to carry out a comprehensive examination according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipeline works and to carry out the water pressure test. Permissible water seepage can be carried out according to the standard of FRP pipe.
- Q:How can I replace the valve on the water supply pipe?
- Steel flanges, three way pipe fittings and single disk connector is connected, immediately install three branch pipe valve, and will be closed fittings and valves at the bottom with concrete pier support, in order to timely restoration of water supply.
- Q:What are FRP pipes?
- Glass fiber reinforced plastic pipeline is a kind of light, high strength and corrosion resistant nonmetal pipe. It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer.
- Q:What is the structure and function of glass fiber reinforced plastic lining?
- The structure is made up of colloid + glass cloth. The construction process is like this:1, carbon steel inner wall grinding acute angle, rust removal2, brushing glue3, cloth affixed4, brushing glue5, cloth affixed
- Q:What is the heat preservation of the plumbing pipe now? I'd like to use fiberglass Seek help from a master
- Glass cotton + glass steel pipe shell: high cost, long construction cycle, good insulation effect.Rock wool insulation: high prices, poor construction conditions, poor heat preservation, water after a mess.Polyurethane foam + yellow jacket: high price, good insulation effect.Galvanized sheet + glass cotton: cheap price, quick construction, good insulation effect.
- Q:What are the main materials used for steel pipes?
- General: steel duct (ordinary steel), galvanized plate (Bai Tie) wind pipe, stainless steel pipe, glass steel ventilation ventilation pipe, plastic pipe, composite pipe ventilation ventilation, ventilation pipe, sandwich insulation board rubberized cloth ventilation tube (such as mine, mine ventilation duct) plastic pipe; ventilation pipe by use of points: General: purification system air supply pipe, central air conditioning and ventilation pipe, industrial ventilation ventilation pipe, suction duct, environmental protection system for mine gas drainage pipe, mine ventilation pipe coating cloth duct; according to the shape: General: round, rectangular, spiral etc.;
