One of the main activities of our company is the manufacture of parts and assembly units for any industry, construction and agriculture, as well as different metalware production.
Our company provides full life cycle of production from design up to delivery of finished products to the warehouse of the customer.
Using our knowledge, experience, advanced metalworking technology and modern equipment we successfully solve problems of any complexity designing drawings based on the customer's specifications or sample parts and we manufacture products in accordance with current technologicalnormative documentation (GOST (Russian standard specification), OST (Branch Standards), TU (Technical Specifications) and customer's drawings. API (for oil and gas industry).

Drill pipe repaip
PetroTool LLC provides drill pipe repair services. Drill pipe repair is carried out under production conditions with modern equipment.
The following operations are performed in the process of repair:
• Cleaning. Inner and outer pipe surfaces are mechanically cleaned;
• Defects Diagnostics. Lock joints and pipe body flaw inspection is performed;
• Pipe straightening. Inspection is performed to correct the curvature of pipe;
• Re-threading. Lock joint re-threading operation is made with modern pipe-threading machines. Control is carried out by gauge rings. API;
• Revitalizing of the lock joint geometry. This operation involves the repair of lock joints by metal welding on the worn surfaces and a subsequent machining of locks up to sizes corresponding to the GOST requirements. API.
• Hard banding (Hard Facing). Hard banding (hard facing) is used to prevent wear of lock joint outer diameter. The operation is performed with flux cored wire. This alloying material has the following advantages:
- substantial increase of service life;
- multiple drill pipe refacing by hard banding (hard facing);
- significant wear reduction of casing pipe due to contact with the drill pipe;
- application of welding technology for drill pipes made of highstrength alloy;
• Phosphating. Thread connections are subjected to phosphating to protect against corrosion and antifriction properties.
