Hangzhou Neetrue Irrigation Facilities Co., Ltd.
杭州奈雀尔灌溉设施有限公司
Hangzhou Neetrue Irrigation Facilities makes PVC and PE lay-flat hose, PVC suction hose, rain-spray hose, backwash hose and trampoline sprinklers. Start by matching the hose family to the job: carrying water, drawing it into a pump, or spreading it along the line. For the double-wing rain-spray hose, the page heading reads NPD-102PD while the size table lists seven NPD row codes, so request a quote against one named row.
Hose families by job
Neetrue's homepage groups its hoses by use: agricultural irrigation, garden watering, construction discharge, mine dewatering and channel cleaning. Pick the family that fits your duty first, then the exact specification inside it. Each family below comes with its own data sheet and its own questions. Alongside the rain-spray range, the catalogue covers the PVC lay-flat hose, the NTS-101GS suction hose and a prefabricated-hole irrigation main pipe.
[1][2][3]Water delivery and lay-flat hose
Ask for the material, how inner diameter is measured, working and burst pressure, temperature range and the coupling arrangement for the grade you choose. Pressure ratings differ by grade and size.
Suction and discharge
Ask for the reinforcement, the vacuum and pressure limits and a coupling drawing for the suction hose itself. A pump intake needs suction figures of its own.
Rain-spray distribution
Fix the model code, hole pattern, pressure, flow per metre and allowed laid length as one set. Work out line spacing from a field layout and use the family spray range only as a first guide.
Pool and recreational products
Backwash hoses and trampoline sprinklers are separate product lines. Request their own material and intended-use documents if you buy them with irrigation hose.
Models and specifications
Quote the exact model, configuration and operating conditions together, and ask the factory to confirm current availability.
Neetrue Rain-Spray Hose, Normal and Double-Wing
Neetrue's rain-spray hose waters a strip of ground through holes punched along the tube itself, with no separate emitters. It comes in a normal flat form and a double-wing form, and both pages carry the same seven-size table, from 20 mm (NPD-1203) to 76 mm (NPD-17612). Each size pairs a hole pattern with a working pressure between 0.8 and 1.5 bar, a flow per metre and a maximum laid length of 50 or 100 m. Choose the profile, then the row, and use the per-metre flow to estimate zone demand. Ask Neetrue to confirm the flow unit and the full order code.
Ask the factory for the current specification sheet for this model.
Read the full specification record ↗Neetrue Prefabricated-Hole Irrigation Main Pipe
Neetrue's prefabricated-hole main pipe feeds drip-irrigation branches from factory-welded outlets. It has a high-strength braided outer layer and a PE-film inner layer. It comes in six sizes from 2 inches (50 mm) to 6 inches (150 mm), and each size has two walls: 0.75 mm rated at 4 bar or 0.9 mm rated at 6 bar, in 50 or 100 m rolls. Neetrue sets the hole spacing to order, so send a dimensioned layout with your quote request and ask it to confirm the outlet thread and seal.

Catalogue reference: NTS-101GS
NTS-101GS is Neetrue's steel-wire reinforced PVC suction hose for drawing water into a dewatering or irrigation pump. It comes in green, black and clear, all with the same ten sizes from 20×26 mm to 100×118 mm (ID×OD). Working pressure is 4 bar up to 1¾ inches and 3 bar from 2 inches up, and rolls are 50, 40 or 30 m depending on size. Order by inside and outside diameter, and choose between the two 4-inch builds. Before ordering, ask Neetrue for the vacuum rating and the temperature scale.
Ask the factory for the current specification sheet for this model.
Read the full specification record ↗Neetrue PVC Lay-Flat Hose
Neetrue sells PVC lay-flat hose in four grades: NTS-1012, NTS-101T, NTS-101BW and NTS-101FH. All four are PVC reinforced with high-strength fibre and come in 50 or 100 m rolls for irrigation and water discharge. Working pressure falls as the diameter rises. NTS-1012 runs from 3 bar at 1 inch down to 1.5 bar at 8 and 10 inches, while 101T and 101FH run from 10 bar down to 5 bar. Use the size tables below to shortlist a grade. The product summaries and tables disagree in a few places, so ask Neetrue to confirm the rating for your size in writing.

Read the full specification record ↗Neetrue NPD-102PD Double-Wing Rain Spray Hose
Catalogue reference: NPD-102PD
Neetrue's double-wing rain-spray hose is a polyethylene tube with side wings that sprays water through rows of small holes along its length. The page heading calls it NPD-102PD and quotes 20–76 mm and a 3–9 m spray range for the family. The table below that lists seven sizes, from NPD-1203 at 20 mm to NPD-17612 at 76 mm, each with its own wall, hole pattern, working pressure, flow and laid length. To buy, pick the row that suits your field and ask Neetrue to quote that code.

Double-wing rain-spray hose: which code to order
The double-wing rain-spray page heads its product NPD-102PD. It quotes a regular-size range of 20–76 mm and a spray range of 3–9 m. The table underneath lists seven row codes: NPD-1203, NPD-1285, NPD-1325, NPD-1405, NPD-1507, NPD-1659 and NPD-17612. Some of those rows start at a 2 m spray range. The second product photograph shows a winged roll labelled NPD-1507.
Read 20–76 mm and 3–9 m as the span of the whole family. One roll has one diameter, one wall and one hole pattern. When you ask for a quote or a sample, name the table row you want. Ask Neetrue to print that row code, or its current commercial code, on the quotation and on the roll label, so diameter, wall, holes, pressure, flow and laid length stay together.
[3][4]Three rain-spray rows compared
Three rows from Neetrue's table show how far the figures move with size. Each row is a complete set of diameter, wall, holes, pressure, spray range, flow and laid length. The flow column is headed I/min/m; ask Neetrue to confirm the unit before you size a pump or a zone.
[3]| Row in Neetrue's table | What the row lists |
|---|---|
| NPD-1203: 20 mm, 0.2 mm wall, parallel three holes | 0.8 bar, 2–3 m spray range, flow 1.3, laid length up to 50 m. Ask how spray range and flow were measured. |
| NPD-1405: 40 mm, 0.31 mm wall, slanted five holes | 0.8 bar, 4–6 m spray range, flow 2.12, laid length up to 100 m. |
| NPD-17612: 76 mm, 0.43 mm wall, slanted twelve holes | 1.5 bar, 6–9 m spray range, flow 5.51, laid length up to 100 m. The widest reach in the family belongs to this largest row. |

Material, outdoor life and custom orders
Neetrue describes the rain-spray hose as polyethylene made from virgin material, with UV and anti-aging properties and long durability. It says the wings stop the hose rolling over and help prevent scratching. A plain profile is offered next to the winged one on the normal and double-wing rain-spray hose page. The site also promotes savings in water, fertiliser, labour and energy, without measured figures.
For outdoor use, ask for the material and wall specification, the allowed pressure and temperature, and the ageing test method and results for the variant you order. Neetrue offers custom colour, logo, size and packing. If you customise, ask which changes touch the technical data and whether the same test documents still cover your roll.
[3]Company background and quality documents
Neetrue's About page traces the business to a family workshop in 1987 and lists the hose families added since. It also mentions ISO certification, SGS product testing and an annual material output figure.
When you shortlist Neetrue, request the dated certificates with holder and scope, and SGS or other test reports that name the hose model and the property tested. A quality-system certificate covers how the factory is run; pressure and ageing performance need product test reports. Ask too about current output, production lines, batch inspection and how a roll is traced back to its production run.
[1][2]Trial the chosen row on your field
Once Neetrue names the row and code, agree a demonstration at its recommended pressure and installation. Ask whether spray range means total width or reach to one side, and whether a uniformity test or pressure-loss curve exists for that row. Our guide to specifying irrigation hose and pipe shows how working pressure and friction loss are read for rain-spray hose.
[3]Identify the roll
Note variant, how diameter is defined, wall, hole pattern, roll length, material and connection parts, and check them against the quotation.
Describe the field
Write down water supply, available flow and pressure, slope, planned line lengths, spacing and exposure. Ask Neetrue for its filtration and operating limits.
Watch the line run
With an agreed safe procedure, record pressure and spray distribution along the line, the test conditions and any interruptions. Set spacing from this distribution, since maximum reach says little about evenness.
Settle service and supply
Get joining and repair parts, instructions, packing, warranty terms and pressure and ageing reports for the same variant. Sample cost, freight and availability come from a current quote.
Warranty, lead time and samples
Neetrue's FAQ, published as images, offers a three-year warranty and lifetime technical support. It gives about seven working days for trial orders and about 20–30 working days for normal orders, and offers OEM/ODM help and free samples. Turn each of these into written terms on your order.
[5]| Neetrue's published term | What to fix in writing for your roll |
|---|---|
| Three-year warranty | What is covered, any outdoor exposure or pressure limits, what a claim needs, and who pays for replacement and freight. Technical support and replacement cover are separate items. |
| Trial and normal delivery | A production and shipping date tied to quantity, custom colour or print, packing and the approved specification, plus a stock check. |
| OEM/ODM and free samples | The sample row, code and length, who handles design, who pays freight, and whether a custom roll keeps the same pressure and ageing documents. |

Questions buyers should settle
Does NPD-102PD come in every diameter from 20 to 76 mm?
That span covers the whole rain-spray family. Each table row is one diameter with its own wall and holes. Ask Neetrue to quote a specific row code.
[3]Can I use the maximum spray range as my hose spacing?
The page leaves open whether spray range is total width or one side, and gives no uniformity data. Work out spacing from the chosen row, your pressure and water supply, with Neetrue's guidance and a field trial.
[3]Does the ISO certificate cover hose pressure performance?
ISO certification concerns the quality system. For pressure performance, ask for the certificate scope and a product test report for the hose model you order.
[2]Is the outdoor life guaranteed for every variant?
Neetrue describes the hose as durable and UV-resistant. Ask for the ageing test behind that and the warranty conditions for the exact hose you buy.
[3]How fast can Neetrue ship?
Its FAQ gives about seven working days for trial orders and about 20–30 working days for normal orders. Get a date for your quantity and specification on the quotation.
