经验
Experience
美国太平洋阀门公司制造这种应用环境非常苛刻的阀门的历史已经有50多年。我们是公认的这种类型阀门的世界领先者。事实上，我们是被所有主要氢氟酸认证颁发机构(U.O.P.,
Phillips石油和Chevron)认可的最早一批阀门制造商的唯一一家，认证范围包括所有通径和压力等级。
Pacific Valves has been manufacturing valves for
this very difficult service for over 50 years. We are considered the pioneers
of this type of valving. In fact, we are the only valve manufacturer originally
approved by all the major hydro-fluoric acid licensors (U.O.P., Phillips
Petroleum and Chevron) in all sizes and pressure ranges.
主要的蒙乃尔部件都用颜色标注，确保正确的材料识别。我们不会停止这种做法。在将任何蒙乃尔部件组装进氢氟酸阀门之前，都经过酸性检测，以确保确实是蒙乃尔材料。这种阀门的制造中的另一个重要方面是关键金属表面(楔形闸板/阀体导向，阀杆/后阀座衬套，等等)的之间的间隙。氢氟酸会与碳钢和蒙乃尔发生化学反应，产生氟化物，聚积在金属表面，从而致使阀门无法正常工作。根据多年的制造经验、检测和试验的总结认识到，必须精确地控制这些间隙，使其能够容许这些累积的氟化物。我们的经验已经使我们能够始终如一地生产适用于这种苛刻应用环境的最好性能阀门。
Primary monel parts are color coded to assure
proper material identification. We do not stop here. Before any monel
part is assembled into a hydrofluoric acid valve it is acid tested to
assure that it is monel. Another important aspect in the manufacture of
these valves is the clearances at the critical metal interfaces (wedge/body
guides, stem/back seat bushing, etc.). Hydrofluoric acid will react with
carbon steel and monel producing a fluoride buildup on the metal surfaces
which can render the valve inoperable. These clearances, developed over
years of manufacturing experience, testing and research, must be precisely
controlled to allow for this buildup. Our experience has enabled us to
consistently produce valves that give the best performance for this stringent
service.
通过认证的质量
Certified Quality
我们所有压力测试和材料检测都是在认证人员的监视下进行，并以他们的准确性签发认证。然后，将一个卡片附在阀门上，注明每次压力测试和材料检测程序都已完成，作为提供给我们的用户的证书。每个阀门都附带着这种证书。
All of our pressure tests and material checks
are witnessed by an inspector who signs off on their accuracy. A laminated
card is then attached to the valve with each test and material check indicated,
as certification to our customer that these procedures have been followed.
Every valve comes with this certification attached to it.

检测每个阀门
Every Valve is Tested
我们采用煤油对我们所有的氢氟酸阀门进行100%的检测。由于下列理由，我们的经验表明煤油是最理想的检测流体介质：
We test 100% of our hydrofluoric acid valves with
kerosene. Our experience indicates that kerosene is the most ideal test
media for the following reasons:
- 防止水滞留。滞留在阀门内部构件的水会加速腐蚀。
It prevents water entrapment; water entrapped
in the valve internals will accelerate corrosion.
- 确保铸件质量。煤油的粘性比水小，因此比其他测试流体更容易定位铸件的缺陷位置。
It assures casting quality; kerosene is less viscous
than water thus will locate a casting defect more readily than other
test fluids.
- 提高阀座检测的可靠性。煤油的粘性小这个优点，再一次使得定位阀座泄漏位置更加可靠。
It provides seat test reliability; again, the
viscosity of kerosen
provides a more reliable seat leakage indication.
我们加长了检测我们的氢氟酸阀门的时间段，这样就进一步保证了阀门性能的质量。此外，我们是在300 PSI的氦介质下检测我们的氢氟酸阀门，以确保铸件的整体性。
We test our hydrofluoric acid valves at extended
time periods that further assure the quality of the valve performance.
In addition, we test our HF Acid valves with Helium at 300 PSI to insure
the castin integrity.
大型室内备品目录
Large in-house Inventory
我们认识到在初始安装后，还要延续我们的服务，我们已经将氢氟酸阀门的备品目录移交给需要维护美国太平洋阀门的炼油厂和发证机构。我们会按备品目录中符合发证机构的规格要求，迅速将有关阀门运送到您的工厂内。
Recognizing the need to continue our service beyond
initial installation we have committed to the refiners and licensors that
an inventory of hydrofluoric acid valves will be maintained at Pacific
Valves. We routinely carry valves in inventory that meet the licensor’s
specificatio for quick delivery to your plant.
