API Standard  Casing Scrapers


Features

Casing Scraper is ideal for the removal of mud, cement, bullets, rust, scale, paraffin, perforation burrs. Maintaining a clean casing I. D. is important to the operation of all tools used in drilling the well. Likewise, packers and similar tools must have a clean surface to grip. Foreign materials on casing walls will frequently cause these tools to become difficult to operation.Standard connections on the Casing Scraper are API REG, Box and Pin. This allows the scraper to be installed in the drilling string between the bit and the bit sub. The bit is run below the scraper to serve as a guide and prevent plugging the circulation hole through the scraper.

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.
