在此功能中,我們正在突出一個項目,該項目需要我們的工程師與客戶合作,以​​設計定製解決方案以滿足其壓力和扭轉測試要求。

Customer Requirement

Whilst developing a new design of connection system, a major subsea connector manufacturer had a requirement for pressure and torsion test equipment. The equipment needed to be designed and installed to achieve their new testing requirements. Their priority was to engage with a company who would work with their design engineers to develop the complete system.

The initial top-level requirements were:

  • 用水和氮氣測試到10,000psi
  • 有能力在需要時在水下試驗氣體。
  • 為了具有檢測內部腔室密封失效的能力,同時氣體測試和量化相關的泄漏率,這不能從初級測試壓力供應側連接或測量。
  • Hydraulic testing to 10,000PSI while subjecting the test piece to external mechanical tortional loading.
  • 確保使用氮氣操作的操作員安全性。
  • 手動對既手動和自動執行所有測試。
  • Tight tolerances on the pressure ramp up and ramp down rates.
  • Operators were to be separated and protected from the high-pressure test area while testing was being carried out.
  • 填充,排出和過濾主試驗蝙蝠的水(用於在水測試下進行氣體)的設施。
  • 完整的數據日誌記錄和報告功能。

初步動作

Initially, we organised an onsite meeting with Hydratron design engineers and the clients design team to fully understand the testing parameters and survey the location for the proposed test area.

挑戰

Initial challenges were identified as follows:

  • 測試件的大尺寸加上水下氣體測試的要求:
    Parts could be up to approx. 3m long with diameters up to approx. 2m and could weigh up to approx. 3000kg.
  • 壓力測試在將外部機械傾斜載荷應用於測試件時:
    這需要設計一種新型的工作,能夠施加非常準確和平穩的機械裝載和卸載試驗片。
  • 測試參數範圍:
    A large range of testing parameters needed to be incorporated into the control system. This was to cover the full range of products and give full flexibility to operators. They needed to either fully manually run various testing or allow the operator to set pre-programmed test parameters with various steps that could then be run fully automatically.
  • 泄漏檢測:
    The operator needed to be able to detect and quantify an internal gas leak on the test piece during gas testing separately to the primary test pressure supply system.

Solution

對於水下的氣體測試,我們探討了製造足夠大的浴缸的選項以包含試驗片,並且設計用於在最大測試壓力條件下的試驗片失效,應承受爆炸。我們的客戶探討了我們的客戶,用專門設計的蓋子探索了將混凝土浴池沉入沉入的測試區域的地板上。

Both options were considered and our client agreed to install a concrete sump, this proved to be the most suitable from both a safety and cost perspective.
