Description Drill pipe joint acts for conversion and connection of drill stem component in petroleum, natural gas and geology drilling work. It is used mainly for connecting of upper drill tools and lower drill tools during drilling operations. Cross-over sub is API standard Material is AISI 4145H chromium-molybdenum steel. We can offer Kelly cross-over sub, Drill pipe cross-over sub, Interim cross-over sub, Drill collar cross-over sub, Drill bit cross-over sub, Swivel cross-over sub, Fishing cross-over sub, etc. All connections are phosphatized, coated with lubricant and provided with thread protectors. All tool joints should be inspected at full length by fluorescence magnetic particle and ultrasonic method. Tool joints are for pipes from 2 3/8" to 6 5/8", grade is E 75, G 105 and S 135; upset style is EU, IEU or IU.
