Brief Introduction
The rupture disk (RD) tubing string testing (TST) valve is a full-opening valve used to pressure test the workstring while running in the hole. The valve is operated after it is stung into a permanent packer or after a retrievable packer is set. To operate the tool, annulus pressure is applied, rupturing the disk moving the mandrel up and pushing the flapper open.


The TST valve consists of:

• flapper valve and spring

• shear pin section

• locking dogs

Features and Benefits

• Flapper valve requires only 4 psi to open.

• Workstring can be pressure tested as many times as required as it is run in the hole.

• Valve shear rating can be predetermined by the rupture disk.

• Valve can also be used for pipe flexing.

Operation

• The RD TST valve is normally set to operate at a pressure around 1000 psi (69 bar) above well hydrostatic at the tool. This allows the tool to be run in and operated when pressuring up on the first annulus cycle. When the TST flapper valve opens, it allows the workstring to fill up. The shear pins hold the mandrel in place. The workstring can be pressure tested as many times as required as it is run in the hole. While the workstring is stationary, a spring keeps the flapper valve closed. After the workstring pressure test is complete, the tool is sheared open when annulus pressure is applied to rupture the disk moving the mandrel up and pushing the flapper open, allowing the locking dogs to engage. The tool is then fully open.

Company Introduction


Xi'an Kingwell Oilfield Machinery Co.,Ltd is a professional supplier for oilfield products according to the API standard.
Our products have exported to USA, Canada, Egypt, India and UEA , etc with 40 FCL contaniers per month.Now, with high quality and short supply and good service, our products have got good reputation home and abroad Here we got some prise as follows.
DST Tools 3 7/8

Design & Development

Kingwell has an ongoing relationship with Xi'an Petroleum University and built up long term cooperation with China Aerospace Group for more than 10 years. Design Department is familiar with CAD and Pro-E facilities and has on rolls qualified & experienced engineers. Now, they are engaged in development of new products as required in the market place. Kingwell' products are validated in-house in a Test Well, a Sub-surface Type Test Facility with simulated well conditions up to 15000 psi Differential pressure , 400°F and Max 450°F.

Quality Systems

A well-established Quality System from Materials receipt to Products delivery ensures consistent quality at all levels of the activity. QMS Procedures & Measurements are tailored to establish high standards of Quality Assurance in the Operations. The Company maintains the 100% Traceability records as per API requirements &NACE MR 0175-2002 Standards and complies with all the legal, statutory and regulatory requirements.

1 Quality control of the raw material

1)The selection of the raw material supplier:our raw materials mainly include alloy structural steel, stainless steel, non-ferrous metal alloy and high nickel alloy, etc, in the selection of the raw material suppliers, we would do the comprehensive assessment of the supplier strictly according to technical requirements .Most of our suppliers are the leading enterprises of the steel production in China and the special alloy are usually purchased from abroad to ensure a higher mechanical properties.

2) The acceptance & Inspection of the raw material:

Ultrasonic flaw detection for every piece of the steel.

Chemical composition analysis for every piece of the steel.

Mechanical performance test for every piece of the steel..

2\Quality control of the seals:

1) O Rings: 100% visual and dimensional inspection for every piece of the O-rings, 15% spot check for the size and hardness test of the o rings. As for the sealing and heat resistance properties of the o rings, we designed a special test device which is equipped with heating insulation equipment that can simulate the down hole temperature and pressure. At present, our fluorine can keep a good performance in the condition of 210 ℃, and 105 Mpa work pressure (maximum pressure ever reached 146).

2) Back-up ring: 100% visual and dimensional inspection for every piece of the back-up ring, as for the test of the sealing and heat resistance, we design and manufacture the special test device, equipped with heating insulation equipment to stimulate the down hole temperature and pressure for acceptance. At present, our company's high pressure back-up seal can keep good sealing performance and deformed a little in the condition of 210 ℃, and 105Mpa work pressure (maximum pressure ever reached 146). It can be used for many times.

3. Quality control of the spring: Apart from the conventional test of the raw material and size of the different springs that used in the tools, we specially designed a test device that equipped with heating preservation equipment to stimulate the down hole temperature and condition to test the spring performance.

4. Quality control of the spare parts processing:

1) Spare parts processing control:In strict accordance with the process and traceability requirements, a test, mark and record of dimension, geometric tolerance and for every piece and every procedure will be conduct.

2) Heat treatment quality control: We have two high temperature heat treatment furnaces that are mainly used for stainless steel and other special material heat treatment. For other materials, we entrust Baoji Petroleum Machinery Company Heat Treatment Plant to do the heat treatment.   For the inspection of the heat treatment, we are equipped with the special inspection machine such as gantry hardness tester, digital universal tensile tester etc.

5. Quality control of the tool assembly and testing process

1) Test equipment: in addition to the conventional hydraulic test pump, tensile testing machine, we also have a pressure sensor and data acquisition system which can accurate and clear record each step of the test.

2) Technical documents: We have a test acceptance list for every tool test that clearly guides the each step of the test.

3) Assembly test: A special inspector will supervise the whole assembly process.
