Special Welded Application

Come rain or shine, we want our customers to trust that we’ll put their interests at the forefront of our work.

We recently demonstrated this through a task we completed for a customer over the long, Labor Day weekend.

The Application: Old.png

  • Transmitter with coplanar manifold
  • Full welded design
  • High pressure application

The Concerns:

  • The transmitter was needed over a long weekend, when most suppliers were closed
  • The customer was finding it difficult to get a replacement manifold any supplier due to Labor Day weekend
  • The manifold had to be capable of withstanding pressure up to 6092 psi (420 bar)
  • The transmitter has a ½” threaded connection, but the manifold needed to have fully welded socket construction
  • Welding on the manifold is not recommended to protect seating surface

Bliss’ Approach: Special Full Welded Design

  • Drawing support within 14 hours (over a weekend)
  • Technical support on site
  • Welding compliance with ASME Piping Code Requirements
  • Calibration & Hydro-testing
  • Delivery time: 1 working day
  • Extra mile effort and customer service

Unique Diaphragm Seal Solutions

At Bliss Anand America, we don’t like saying the word no. We know that we have experienced engineering and production teams, and armed with the right tools, we believe they can solve any problem.

So when BP came to us with a unique solution, we put our best people to the test. Working with our partners Badotherm, Bliss created a special solution to suit BP’s requirements.

The Application:

  • Very high process 
temperature – 760°F
  • Small process connection – 
no larger than 1”
  • Process fluid is a gas with high levels of hydrogen, and small amounts of H2S and NH3

The Concerns:

  • Are there any fill fluids that handle temperatures up to 760°F?
  • EJX430 (preferred Yokogawa gauge pressure transmitter) can only handle up to 248°F
  • Durability of gold coating – specifically regarding thermal shock at startup
  • Materials and NACE certification requirements

Bliss-Badotherm’s ApproachIMG_1625

  • Use BSO-48 as a fill fluid to handle temperatures ranging from -4 – 788°F
  • Use EJX530A transmitter rather than EJX430, as it contains fully welded construction (no gaskets or threads). It is highly recommended for high temperature/high pressure applications
  • Supply a 1 piece BF design with a thermal reducer
  • Supply gold-coated seal with 40μm on 316L diaphragm and other wetted parts. Alloy 400 specified by customer is only suitable for temperature below 392°F

Through perseverance, a lot of back and forth and discussion, and a creative mindset for solving problems, Bliss-Badotherm is now the only supplier (globally) for gold-coated seals with high temperature fill fluids.

Diaphragm Seal Repair

Diaphragm Seals are typically used with pressure transmitters, but can also be used with pressure gauges and pressure switches. They are recommended in applications where the process medium is:

  • is aggressive, corrosive, toxic and/or highly viscous
  • has a (extremely) high or low temperature
  • has crystallization and/or polymerization

Given the above applications, seals are often subjected to harsh environments, rendering them damaged. High temperatures can ruin seals by heating fill fluids. High pressure water jets, corrosive materials and dents can also cause damage.

Bliss Anand understands that constantly replacing your diaphragm seals can get expensive, so we offer Diaphragm Seal Refurbishment Services. We will replace an old Diaphragm Seal from an existing transmitter-seal assembly at half the cost of a new transmitter-seal assembly, so you can get your project running smoothly again with minimal disturbance.

Benefits of Seal Renewal

After

  • Significantly more economic than ordering a completely new instrument
  • Before executing the order, the transmitter is tested for proper functioning, so there are no unnecessary costs for a repair executed in vain
  • All brands of pressure transmitters are compatible and new Diaphragm Seals can be mounted to them
  • A clear and written quotation, so you have a clear insight in the costs and actions beforehand
  • A repair/renewal of Diaphragm Seals often provides valuable information regarding the process and offers the opportunity of a better solution for increased lifetime

Boiler Water Level Gauge

Page 1 - diagram 1

The BN200 series is bi-color boiler water level gauge that meets ASME Section I –Power Boiler requirements, using high quality material and adhering to safety standards. The BN200 Bi-Color water level gauge can handle a maximum pressure of 220 kgf/cm2 (216 barG), and a maximum temperature of 701°F (372 °C).

Principles of the BN200 Series Bi-Color water level gauge

The air phase in the water level gauge is red and the liquid phase is green, ensuring a very clear visual of the water level. When the prism shaped liquid chamber of the water level gauge is filled with a clear liquid, due to the prism effect of the liquid chamber section, the light injected is bent extensively. However, when the liquid chamber is filled with air (gas) the light bending effect is slight and almost all of the injected light travels straight.

When color filters (red/green or red/blue) are set in the illuminator, as show in the diagrams on the left, the following different light phenomena occur: red light is transmitted when air (gas) covers the glass surface while green light is transmitted when transparent liquid covers the surface.

  • Developed for use with the BN200 series water level gauge, we have created a composite unit comprised of a special metal ring fused to glass that is extremely heat resistant. As the glass and metal are integrally fused together, the glass is stronger than most products, reducing the chance of glass damage almost completely.
  • Our innovative glass solution contains several oxides to improve its resistance to alkalis. These include zirconia, rare earths and alumina, all of which are highly resistant to dissolving, and maintain this property when incorporated into glass. It also contains properties found in regular glass such as heat stability and mechanical strength, allowing it to be used for industrial applications.

Low Gauge Pressure Diaphragm Seals

Standard diaphragm seals limit you to measuring down to 100mbar. Beyond this, measurements are inaccurate and often not possible at all.

This can be problematic when trying to measure lower pressure applications, so we are offering you a solution – our Low Gauge Pressure Seals, developed for measuring pressures as low as 5mbar with minimal temperature effects.

Screen Shot 2017-05-22 at 11.20.16 AM

Typically, in order to obtain low-pressure readings in applications, nitrogen blankets are used to prevent process gases from entering the atmosphere. You need to be able to accurately measure and monitor the pressure of the nitrogen blanket in order to minimize its interference with the process in the vessel.

Unfortunately, nitrogen blankets with an overpressure are unstable in a corrosive environment that uses diaphragm seals. The combination of the seal and the low overpressure range (approximately 10mbar for nitrogen blankets) results in high temperature effects when exposed to process and ambient conditions. The high temperature effects then lead to unreliable and unstable data.

With the Low Gauge Pressure Diaphragm Seal, the minimum GP range reduces from 80 mbar with a standard Diaphragm Seal to only 5 mbar with the LGP Diaphragm Seal. Similarly the ambient temperature effect reduces from 0.006 psi (0.4 mbar) per 50°F (10°C) to 0.0004 psi (0.03 mbar) per 50°F (10°C), while the process temperature effect reduces from 0.006 psi (0.39 mbar) to 0.001 psi (0.09 mbar).Screen Shot 2017-05-22 at 11.20.26 AM

The LGP Diaphragm Seal also provides additional benefits:

  • The way of mounting the transmitter to the vessels has no effect on the zero and span adjustments of the transmitter, so there is no zero adjustment required
  • There is no effect on the performance by a change in the density of the fluid caused by ambient temperature fluctuations; so there is no mounting effect.
