Reinforced Graphite Sheet

Graphite Sheet Reinforced with tanged metal insert is made from B201 Flexible graphite sheet through specially pressing or sticking process. The insert materials can be SS304, SS316, Nickel, etc. It used in kinds of conditions, and various gaskets.

Ramie fiber packing

Ramie Fiber Packing is Highest quality ramie fiber impregnated with light-colored, special PTFE and inert lubricant during square plaiting operation. It is not harsh on shafts and stems.

Acrylic Fiber Packing

Acrylic Fiber Packing is a braided sealing material manufactured from high-quality acrylic fibers. It is designed for general industrial applications where moderate temperature and chemical resistance are sufficient, and cost-effectiveness is a priority. This packing offers a balanced combination of good mechanical strength, excellent abrasion resistance, and reliable sealing performance at an attractive price point.

PTFE Packing

PTFE gland packing is a square or round braided sealing material made from polytetrafluoroethylene (PTFE) fibers. Installed in the stuffing boxes of pumps, valves, and agitators, it provides dynamic and static sealing for valve stems and rotating shafts by being compressed to fill the clearance space, thereby preventing fluid leakage. Commonly known as Teflon packing, it is a type of braided packing seal, distinct from expanded PTFE sheets or PTFE gaskets.

How to Distinguish Between Gray Iron Valves and Ductile Iron Valves

Under Chinese national standards (GB), ductile iron is typically designated as QT400-15, QT400-18, etc. Here, "QT" is the abbreviation for ductile iron (spheroidal graphite iron), "400" indicates the tensile strength, and "15" or "18" indicates the elongation percentage. International designations vary widely; for example, European standards use EN-GJS-400-15/18, while German standards use grades such as GGG40, GGG40.3, and GGG50.

HDPE Sheet

HDPE, scientifically known as high-density polyethylene, is a thermoplastic made from the polymerization of ethylene monomers. HDPE sheet is made primarily from HDPE resin through processes such as extrusion or compression molding.
