Many people simply regard valves as simple on‑off switches. However, once you look into their internal structures, you will find that different valves deliver completely different performance even for basic open‑close tasks.
For chemical, environmental‑protection and water‑treatment industries, PP, PPH and PVDF valves stand out as mainstream options for corrosive fluid transport, thanks to outstanding corrosion resistance, light weight and cost‑effectiveness.
Below is a quick overview of the 9 major valve categories:

Jiangsu Jiqing Pipe Group is a leading domestic manufacturer of β-PPH pipes. Supported by intelligent production lines, complete piping matching system and end-to-end engineering service, we deliver distinctive product and comprehensive operational strengths.

Pipe selection for new energy projects differs greatly from traditional chemical projects. Pipes must deliver corrosion resistance & pressure resistance, maintain medium purity, resist creep deformation, and balance service life with project costs. Improper pipe selection leads to production shutdowns, electrolyte leakage and safety hazards. Jiqing Group summarizes key guidelines to simplify your new energy piping material selection.

Statistics show 90% of flange leakage issues have nothing to do with pipe quality. The main culprits include aging gaskets, flange misalignment, uneven bolt tension, and thermal expansion & contraction of pipes. Locate the leakage point and root cause first, then apply targeted fixes to resolve most flange seepage permanently.

1. Two Major Types of Flange Leakage
Flange leakage falls into two distinct categories with different root causes. Blind uniform repairs will lead to recurring leaks.

Most construction workers know outdoor welding is prohibited without protection on rainy days. Yet many ignore wind hazards. Different wind speeds affect welding temperature and joint cleanliness, resulting in pipe leakage, joint separation and cracking in later service.
1. Construction Standards Based on Wind Scale
A stable ambient environment is an essential prerequisite for qualified hot-melt welding of plastic pipes.

The PPH pipe, with its outstanding anti-corrosion performance and stable usage characteristics, has become the preferred pipe material for transporting corrosive media in the chemical industry. But how much do you know about the PPH pipe? Today, let's break it down and explain the PPH pipe to you in detail, so that you can avoid unnecessary detours and potential risks during use, and easily handle various construction and usage problems.
