Flange standard and size (DN / NPS, PN or Class), medium, temperature, pressure, drawing or sample for non-standard shapes, quantity法兰标准及规格(DN/NPS、PN或Class)、介质、温度、压力、异形垫请提供图纸或样品、数量
Yes. Send a drawing, a photo with dimensions, or the old part and we will quote custom die-cut or machined gaskets.可以。请发图纸、带尺寸的照片或旧件,我们为您报价定制冲裁或加工垫片。
It depends on medium, temperature and pressure. Graphite filler suits steam and oil; PTFE filler suits corrosive media. Inner and outer rings protect the winding and centre the gasket. Tell us your conditions and we will recommend.取决于介质、温度和压力。石墨填料适合蒸汽、油品,四氟填料适合腐蚀介质;内外环起保护和定位作用。告诉我们工况,我们给出建议。
