factory customized High Speed Steel Step Bit - Non-magnetic hang sub – Herui

Factory Direct Supply LWD/MWD Non-magnetic hang sub includes an integral sub section. The integral sub section has an inner diameter that matches the instrument flow cylinder assembly, the probe tube and the centralizer set on the probe tube. The inner hole of the integral sub section has multiple step holes. The uppermost inner hole is equipped with an instrument flow tube assembly, the middle step hole is equipped with a probe tube, and the lowermost integral sub-section is used to isolate the distance between the instrument and the magnetic drilling tool. Non-magnetic hang sub of the utility model is equivalent to combining the original three-part short section into a whole, removing the middle threaded connection link, greatly improving the downhole safety of the instrument, and ensuring effective isolation of the instrument and the In the case of the distance of the magnetic drilling tool, the distance between the instrument and the drill bit is shortened.

Non-magnetic hang sub is mainly used to determine the direction of the borehole during directional well drilling. At the same time, it creates a non-magnetic environment for the magnetic measuring instrument during the orienting process to ensure that the data measured by the magnetic measuring instrument is true geomagnetic information.

Our company have two grades of non-magnetic suspension pup joints , P530 and P550

The use and maintain of the sawblade

◎ The carbide tip of sawblade is very sharp, so process of using must be prevent the carbide tip.

◎ PeriodicaI cleaning and support the machine,the spindle’s running tolerance must be less than h7.

◎ The flanges must be parallel to each other,must be of the same diameter 1/3 of the sawblade’s diameter(formuIti—rip saw blade is 1/2.

◎ When instaIIion the sawbIade,it shaII be 5-6 teeth higher than board surface．

◎ Before operation,check the firmly of the sawblade,be sure nobody in front of the machine. Do not feed of operation check whether the machine is good for operaiton. Periodical check the function of the machine,the certicaI jump is less than ±0.02MM,and the flap is less than ±0.01.

◎ After continuous use,must be removed and cleaning the sawblade,get rid of the resin and sawdust of the sawblade of both sides.Other wise it would beinfluence the effect of using the sawblade.

◎ Deposit of the sawblade,must not be layer the sawblade,it is putted in the originaI package inside.

The renovate of the sawbIade

◎ The renovate of the carbide sawblade While it no longer sharpen and the horizontaI piece coarseaess. The power of using sawblade machine obviously Increase. When process materiaI,the materiaI appearred burst. The carbide tip exhaust more than 0.02MM.

◎ For the renovate the sawblade,it shouId be grinding by the a formal company, so be sure the quality of the sawblade after renovating.
