Socket reductor de PPR

Descripció

La presa reductora PPR és similar a la presa igual, la principal diferència és que els diàmetres interiors de les dues interfícies de la presa reductora són diferents i els seus dos extrems es poden connectar a tubs PPR de diferents diàmetres exteriors. Quan cal connectar dues canonades de diferents mides, solem optar per utilitzar la presa reductora.

Identificar la qualitat

1. "Look" appearance. A good PPR reducing socket is soft and uniform in color, without variegation.

2. "Touch" the texture. A good PPR reducing socket is 100 percent PPR raw material (without any additives), the texture is pure, the surface is smooth and clean, the hand feel is soft, and the pseudo PPR pipe feels smooth. Generally speaking, the rough particles are likely to be mixed with impurities;

3. "Smell" the smell. The main material of PPR pipe is polypropylene. Good pipes have no smell, and poor ones have strange smell,it is likely to be mixed with polyethylene instead of polypropylene;

4. "Pinch" hardness. PPR tube has considerable hardness, and a tube that can be deformed by pinching is definitely not a PPR tube;

5. "Amount" of wall thickness. You can use a vernier caliper to measure whether the wall thickness of the pipe is up to standard and uniform. Generally, good pipes are produced in strict accordance with the national standard.

6. "Listen" to the sound. The landing sound of the PPR pipe is dull, and the landing sound of the pseudo PPR pipe is clearer.

7. "Smash" elasticity. A good PPR pipe has good "resilience" .If it is easy to smash, naturally, it is not a good PPR pipe.

8. "Burn" smoke to smell.

Les canonades de PPR amb plàstic reciclat i altres impureses barrejades a les matèries primeres emeten fum negre i tenen una olor picant. I els bons materials no emetran fum negre i olor després de cremar-se, i el líquid fos encara està molt net després de cremar-se.
