Product Description
Execution standard: Generally follow API SPEC 5CT and API SPEC 5B standards to ensure the uniformity and standardization of product quality and specifications, in order to meet the requirements of the petroleum industry.
Material: Common materials include H40, J55, N80-1, N80Q, L80, P110, etc. Different materials have different strengths and properties, and the appropriate material can be selected according to the specific usage environment and working conditions.
Specification: The outer diameter range is generally between 55.88 - 141.3mm (1.9" - 4 1/2"), and common specifications include 1.315", 2-3/8", 2-7/8", 3-1/2" etc. It can meet the connection requirements of different pipe diameters for oil pipe.
Thread type: There are mainly non-thickened (NUE), thickened (EUE), special gap (SCC), etc. In addition, there are short round (STC), long round (LTC), trapezoidal (BC) and other thread types. Different thread types have different sealing performance and connection strength, and are suitable for different well conditions and operation requirements.
Product features: The size processing is precise, with strict internal control accuracy, and good anti-sticking performance. Its structure can alleviate the stress concentration at the root of the external thread of the single cone threaded connection oil pipe, and is not prone to fatigue fracture, resulting in good connection effect and effectively preventing the accident of oil well pipe column detachment.
Surface treatment: The inner and outer surfaces are usually treated with phosphating, and blackening treatment and painting can also be carried out according to requirements to improve the anti-corrosion performance and extend the service life.
Usage: It is mainly used in the oil and gas extraction fields, connecting multiple oil pipes into a pipe column to achieve the transportation of oil and gas, and can also be applied in pipeline systems such as chemical and water supply.
Packaging: Generally, it is packaged in cardboard boxes, wooden boxes or pallets, and the packaging method can be customized according to customer requirements to facilitate transportation and storage.
