Worried about making a mistake when choosing PPR pipes for your home renovation? 5 questions and answers to help you distinguish between good and bad!
Q1: Can you judge the quality of PPR pipes by their appearance? What do high-quality PPR pipes look like?
Of course! Appearance is the first step in judging the quality of PPR pipes. High-quality PPR pipes have a uniform and bright color, without any impurities or spots, and the surface of the pipe wall feels smooth and delicate to the touch. This is a direct reflection of brand-new pure PPR raw materials and standardized production processes. On the other hand, inferior pipes are either dark and yellowish in color or full of impurities and particles, and feel rough and astringent to the touch. These types of pipes are likely mixed with recycled materials or waste plastics, so just pass on them. Jianlong brand PPR pipes have a clean and uniform color and just the right amount of gloss. You can tell the difference from inferior pipes at a glance when they are placed on the shelf, and their quality is immediately apparent.
Q2: Can you tell if the raw materials of PPR pipes are pure by smell? How exactly is this done?
Sure! This is a key trick to determine if PPR pipes are made from virgin materials. Take a small section of pipe and gently heat the pipe wall with a lighter (be careful not to heat it for too long to avoid burns), then smell it closely. High-quality PPR pipes, when heated, will only emit a faint plastic smell similar to melting candle wax, without any pungent odor, indicating high raw material purity. Inferior pipes, on the other hand, will emit an unpleasant chemical odor when heated, even causing eye irritation and a pungent smell. This is because they contain a large amount of recycled materials and waste plastics. Using such pipes for plumbing is tantamount to creating a hidden danger in your home. Jianlong brand PPR pipes can withstand this test; even when heated, they will not have a pungent odor, making the raw material quality immediately apparent.
Q3: Are there differences in weight between PPR pipes of the same specifications? Are heavier pipes better?
There is a difference, and heavier pipes aren't necessarily better! The difference is immediately apparent when you hold PPR pipes of the same specifications in your hand and weigh them. High-quality PPR pipes are made from brand-new, pure materials, with a uniform and moderate density, so they won't feel "heavy" in your hand. Inferior pipes, on the other hand, to reduce weight and mislead consumers, will add large amounts of calcium powder and impurities to the raw materials, resulting in a higher density and a heavier feel. When purchasing, try comparing the weights of several pipes of the same specifications; those that are unusually heavy can generally be eliminated. Jianlong brand PPR pipes strictly adhere to raw material ratio standards, with a uniform and moderate density, a light yet substantial feel, direct proof of high-quality pure materials.
Q4: Can you tell the toughness of a PPR pipe by pressing it? What are the standards for the hardness and flexibility of good pipes?
Yes! Gently press the wall of the PPR pipe with your hand to feel its softness and elasticity. This step directly reveals the pipe's toughness and durability. High-quality PPR pipes have just the right amount of softness and hardness; you can feel a noticeable elasticity when pressed, and it quickly returns to its original shape after releasing the pressure, leaving no dent. This type of flexible pipe has strong impact resistance, is not easily broken during installation, and is suitable for various complex water pipe layouts. Inferior pipes are at two extremes: either they collapse easily when pressed and do not return to their original shape after releasing the pressure, or they are as hard as a rock, with no flexibility, and may crack with slight bending. Jianlong brand PPR pipes have undergone repeated adjustments to their softness and flexibility, and are very resilient when pressed, neither too soft nor too hard and brittle, making them particularly suitable for the needs of hot and cold water pipes in home decoration.
Q5: Is it necessary to measure the pipe wall thickness? What are the dimensional requirements for high-quality PPR pipes?
Absolutely necessary! This is a crucial step in verifying whether the PPR pipe manufacturing process meets standards and whether quality control is rigorous. Use calipers or a ruler to measure the wall thickness and diameter of the PPR pipe. High-quality PPR pipes have a uniform wall thickness, without any unevenness, and the actual measured dimensions perfectly match the specifications marked on the product. Inferior pipes often exhibit discrepancies – the marked wall thickness may be 2.8mm, but the actual measurement might only be 2.2mm, or even inconsistent. Using such pipes can easily lead to bursting under high water pressure. Jianlong brand PPR pipes undergo multiple dimensional checks throughout the entire production and delivery process, ensuring uniform and consistent wall thickness, with actual dimensions perfectly matching the marked specifications, and guaranteeing superior pressure resistance.
When choosing PPR pipes, don't just look at the price. Remember these 5 tips in the Q&A section to easily avoid the pitfalls of inferior products. Jianlong Plastics focuses on the production of high-quality plastic pipes. Every Jianlong brand PPR pipe undergoes strict quality control, with full traceability from raw materials to finished products, giving you real peace of mind!
