Complete Pulp Mill Piping Systems for Paper Industry Machinery

In any paper mill equipment installation, the piping network is the circulatory system that connects pulpers, screens, cleaners, and towers. Our pulp and paper machinery supply includes fully matched stainless steel pipes (S304, PN10 from DN15 to DN600), together with all necessary valves, flanges, and fittings. This paper industry machinery package ensures leak‑free transport of stock, white water, and chemicals. From chain conveyor feed to high‑density cleaner rejects, every meter of pipe and every elbow is precisely specified to match your process flows. Using a complete paper mill line approach, we pre‑engineer the entire piping layout to reduce field welding and shorten erection time.

Key Components for Pulping Workshop

The material list for the pulping workshop (Leizhan Indonesia 4300 packaging paper line) shows the depth of our paper manufacturing machine support:

Stainless Steel Pipes: S304, PN10, sizes from DN15 to DN600, with total lengths exceeding 1,000 meters.

Pulp Gate Valves (ZT9928): PN10, DN100‑DN600, all stainless steel body for abrasive stock.

Check Valves (H71H‑10): DN150‑DN400, vertical installation to prevent backflow.

Fittings: 1.5D 90° & 135° elbows, concentric/eccentric reducers, equal and reducing tees, and soft connections (rubber expansion joints).

Flanges: JB81‑59, PL type, PN10/PN16, stainless steel with matching gaskets.
All pipe‑contact parts are 304 stainless steel, ensuring corrosion resistance and long service life. This paper production line integration includes everything from the drum pulper discharge to the dump tower, coarse screen, and low‑density cleaner stages.

We deliver more than just equipment – we deliver complete, ready‑to‑install piping systems for your paper making line. Our pre‑fabricated spools minimize on‑site welding, reduce installation cost, and speed up commissioning. Whether you need a small industrial paper machine upgrade or a full turnkey paper production line, our engineering team matches every valve, fitting, and flange to your process requirements.
