Velan标准的研磨密封焊接钨铬钴合金6阀座环面
VELAN STANDARD GROUND AND LAPPED SEAL WELDED
SEAT
RINGS FACED WITH STELLITE 6 |
- 由Velan首创的公认的最先进的技术。
Pioneered by Velan and considered state-of-the-art
technology.
- 防泄漏焊接装配。
Welded-in leakproof.
- 焊接质量经过100%的测试。
Weld quality 100% tested.
- 钨铬钴合金6阀座面,使用寿命更长。
Stellite 6 seating faces for long service
life.

- 焊接装配后,进行研磨,抛光精度达到2 RMS。
Ground and lapped to 2 RMS finish after
weld-in.
- 通常用于温度达538°C蒸汽,油和气。
Standardized use for steam up to 1000°F
(538°C), oil and gas.
- 钨铬钴合金面耐磨性优于13 CR楔板,而且更易于维修和更换。
Stellite face will wear less than the 13
CR wedge, which can easily be repaired or replaced.

与螺纹旋进的13 CR阀座的竞争优势
COMPETING SCREWED-IN SEATS IN 13 CR |
- 可能会因腐蚀而导致松弛,从而导致实际上的泄漏。
Can loosen up due to corrosion and cause
substantial leakage.
- 更换很困难甚至不可能。
Replacement is difficult if not impossible.
- 螺纹可能被腐蚀并导致泄露。
Threads can corrode and cause leakage.
- 螺纹松懈后,阀座就处于不安全状态。
Seat is unsecured from unscrewing.
|
|
- 由于温度波动、腐蚀或振动,阀座可能松动,并导致泄露。
Seat can become loose due to temperature
fluctuations, corrosion
or vibration, and can leak.
- 不适用于蒸汽应用场合。蒸汽和其它流体会拉曳阀体螺纹,造成阀座松动以至无法维修。
Not suitable for steam service. Steam and
other fluids will wire draw body threads of loose seats beyond
repair.
- 13 CR阀座仅仅适用于某些流体。
13 CR seat suitable only for certain fluids.
