家庭用および産業用 PPR パイプ設置ガイド

In the global wave of building water supply system upgrades, PPR (ランダムコポリマーポリプロピレン) パイプ are gradually replacing traditional metal pipes with their high temperature resistance, corrosion resistance and zero leakage characteristics. As a professional exporter who has been working in the pipeline industry for 10 年, Let us reveals the PPR pipe standard installation process for you to help you create a reliable pipeline system with 50 years of maintenance free.

初め,Industrial and Home use PPR Pイペラインあ利点 (Required reading before construction)

1. Material C嫌がらせ

Operating temperature range: -20 ℃～ 95 ℃ (better than the upper limit of 60 ° C of PVC pipe)

圧縮強度: 2.5MPa at 20℃ environment (through ISO 9001 認証)

Sanitary rating: NSF/ANSI 61 Drinking water system certification

2. Economic C比較

Type of pipeline	設置費用	Maintenance cycle	Service life
Galvanized steel pipe	high	3-5 年	15 年
銅管	Extremely high	8-10 年	25 年
PPR tube	中くらい	Maintenance-free	50 年

Professional grade PPR tube installation 7-step method

ステップ 1: Accurate mapping and cutting

Use a laser rangefinder to ensure ±2mm accuracy

Cutting tool selection:

Rotary cutter (DN20-DN63 pipe diameter)

Electric pipe cutter (DN75 + large diameter pipe)

ステップ 2: Key technologies of hot melt welding

Temperature control: 260±5℃ (equipped with digital temperature control welding machine)

Heating time reference table:

Pipe diameter (mm)	Heating time (s)	Engaging time (s)	Cooling time (分)
20	5	4	2
32	8	6	4
63	24	8	6

ステップ 3: Pipe fixing points

Pipe clamp spacing standard:

Horizontal pipe: DN20 pipe @600mm

Vertical tube: DN32 tube @1200mm

304 stainless steel spring clamps are recommended

5 Solutions to common installation problems

1. Virtual welding problem diagnosis

Cause: pipe/fittings are not clean, insufficient heating time

Rapid detection method: 30° bending test after welding

2. Winter construction precautions

When the ambient temperature is < 5℃, the cooling time is extended by 50%

Use [brand name] low temperature special PPR tube (glass transition temperature -15℃)

3. Lintel sleeve installation specifications

Casing diameter ≥ pipe outer diameter +20mm

Fill with flexible flame retardant material for seal

4.Professional tool set recommended

Intelligent temperature control welding machine: with temperature compensation function

Multifunctional pipe cutter: Support 20-110mm full specification

Pipe detector: can measure the depth of welding penetration

5.How to choose PPR pipeline?

1. High quality raw materials

The Nordic chemical RA130E raw material is used, the ash content is < 0.02%

2. Global certification system

It has obtained 28 international certifications such as CE, WRAS and SGS
