Product standards:

Design and manufacturing: API 600 flange dimensions: length: ANSI B16.5 structure ANSI B16.10

Butt welding size: ANSI B16.25 pressure - temperature: ANSI B16.34 inspection and test: GB13927

Product features:

1. The product design and manufacture according to API standard, reliable sealing, good performance and can be used to form a complete set of imported equipment.

More than 2.600 Lb disc and seat sealing using department too vertical (stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, corrosion resistance, good abrasion resistance, long service life.

3. The stem by conditioning and surface nitriding treatment, good corrosion resistance and abrasion resistance.

4. Adopting the wedge gate structure, large diameter set the rolling bearing, easy opening and closing.

5. Variety complete body material, packing, gasket, reasonable selection according to actual working condition or the user requirements, can be applicable to all kinds of pressure, temperature and medium conditions.

6.1500 LB, 2500 LB midplane USES pressure self-tightening seal structure. Rise with inner pressure seal performance, high reliability.

7. Pour the seal is made of stainless steel threaded connection seal or ontology austenitic stainless steel welding and become, reliable sealing, packing replacement and repair without downtime, convenient and quick does not affect the system running.

Product use:
