PAKISTAN PAPER MILL PROJECT
WEIZIDOM and BSP began their collaboration in 2019 with a small sample. The partnership has lasted seven years, with orders totaling US$1.2 million. It is because we have always kept our original aspiration in mind, always put customer needs first, and strictly control product quality that our customers have seen our seriousness and responsibility in our delivery time and time again, which has made WEIZIDOM a long-term partner of BSP.
Main Products:
> DIN Seamless Pipes & Fittings
> DIN Knife gate valves /
> DIN Flanges & Gaskets, etc.
Why BSP Chose WEIZIDOM as Their Long-Term Partner
✅ 1. Product Quality You Can Trust
Every valve and fitting from WEIZIDOM undergoes 100% inspection before shipment.
We use CNC machining centers, hydrostatic testing, and spectral material analysis to guarantee compliance with DIN, EN, and ISO standards.
✅ 2. Complete Material Traceability
Each component is tagged with material certificates (EN10204 3.1), ensuring full traceability from casting to final assembly — a critical factor for BSP’s quality assurance systems.
✅ 3. Customized Engineering Solutions
WEIZIDOM doesn’t provide one-size-fits-all solutions.
For BSP, we designed customized knife gate valves with optimized sealing rings and wear-resistant coatings to handle fiber-rich pulp flows.
Our engineering team also provided on-site installation guidance and technical drawings for better integration with BSP’s process pipelines.
✅ 4. Fast Response and Reliable Delivery
In industrial projects, timing is everything.
WEIZIDOM’s flexible production capacity — supported by five major manufacturing bases across China (Wenzhou, Lianyungang, Shandong, Anhui, Tianjin) — ensures that urgent orders can be completed efficiently without compromising quality.
✅ 5. Long-Term Value, Not Just Price
BSP continues to choose WEIZIDOM because we offer value beyond price — consistent performance, long service life, and technical reliability that reduces operational risks and long-term costs.
Applications in Paper Mill Systems
