Brief Introduction
The rupture disk (RD) bypass pressure test valve is a full-opening, single-shot annulus operated valve. The tool functions as a pressure testing and a bypass valve. The tool is commonly used at the start of a drill stem test to allow the tool string to be pressure tested against the closed ball valve. This tool also has a bypass below the ball that allows the tool string to be "stung in" to a production packer. To operate the tool, annulus pressure is applied, rupturing the disk, closing the bypass ports, and opening the ball valve.
Features and Benefits
The tool is composed of three sections:
• The ball valve section is at the top of the tool and consists of a ball valve, operating pins, and collet fingers. The collet fingers expand, allowing the power mandrel to continue traveling up to open the ball valve and close the circulating ports.
• The power section consists of a power mandrel case and rupture disk available for a wide range of pressure applications. The rupture disk bursts at a predetermined pressure, allowing annulus pressure to be applied to a differential area on the power mandrel. The power mandrel moves up, first pushing the ball valve open, and then closing a set of circulating ports.
• The bypass section is at the bottom of the tool and consists of a set of ports and a power mandrel. When the rupture disk bursts, the power mandrel moves up, closing off the ports and communication between the annulus and the tool string.
Operation
The rupture disk bypass pressure test valve is normally set to operate at a pressure around 1000 psi (69 bars) above well hydrostatic at the tool. This allows the tool to be run in and then operated when pressuring up on the first annulus pressure cycle. Another method of running the tool is to use it for pressure testing the tool string and then use well hydrostatic while running in to operate the tool automatically. When running the tool in this mode, it is acceptable to use shear pins to determine the operating pressure. If an accurate operating pressure is required, the rupture disk must be used.
Note: This tool should have the only closed ball valve while running in. If any other closed ball tools are run in the string, a bypass must be run to avoid an air chamber between the closed balls.
The air chamber trapped between the balls could cause the tool to not operate, operate a very high pressure, or cause damage to the tool.

KINGWELL INTRODUCTION
Xi'an Kingwell Oilfield Machinery Co.,Ltd is an established, financially stable manufacturing company and manufactured products are technically qualified which match the highest quality & reliability standards. We fulfill all the requirements to become a reliable supplier of any National and International majors in this field.
Here we got some prise as follows.
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.
