Product description
Metallurgical production offers to place an order for a wide range of steel pipes, length up to 28 000 mm in length, external dimensions from Ø2 mm to Ø1450 mm. If necessary, internal or external processing of pipes will be made, chamfering, heat treatment according to standard or individual mode, etc. will be performed upon agreement with the buyer. Steel pipe is produced in different ways and for different branches of pipe products application.
Drill pipes and casing steel pipes are manufactured for oil and gas industry according to both GOST R 53366-2000, GOST 51245-99, GOST 50278, GOST 6238, GOST 31446, API Spec 7-1, API Spec 7-2 standards and to customer's individual technical requirements according to newly developed TC/TA, technical protocols with possible length up to 28 m, drill pipes are subdivided:
- Drill pipe, type P
- Steel drill pipe thick-walled non-magnetic - TBTN/FLEX
- Steel drill pipe weighted balanced nonmagnetic - UBTSN
- Weighted balanced drill pipe - UBTS
- Heavy wall drill pipe - TBT
- Drill pipe leading square section - VBT
- Drill pipe leading square section compounded - VBTS
- Drilling pipe 20хgsnm, type BP, etc.
Large-diameter steel pipes from 500 mm according to GOST ISO 3183-2015, GOST 31447-2012, GOST 20295-85, ANSI/API spec 5L/ASTM A106/ASME SA106/EN 10216-2 Specification for Line Pipe and other specifications (including individually developed), for main oil and gas pipelines and transportation of mineral resources from the point of field production to the point of storage, processing and the final buyer are made of steel sheets by welding on specialized equipment, including the application of internal anti-corrosion coatings, etc. , external coatings in accordance with the requirements of operating loads and order.
According to the expanded capabilities of the company, industrial seamless pipes are produced for various areas of machine building and other industries:
- hot-rolled/hot-deformed
- stainless / corrosion-resistant
- forged / honed
- cold-rolled / cold-deformed
- bearing (ball bearing steel grades)
The following types of 20хgsnm (20хгснм) oil grade casing and pump-compression (tubing) pipes are used for well strengthening and geological prospecting work, among others:
Casing (used to ensure the integrity of well walls for the entire period of operation and tightness of structure of interpipe joints):
- Steel OTTG casing pipe
- Casing pipe with a triangular thread
- Casing pipe OTTM
- Casing pipe TBO, etc.
Pump-compression pipes (used to provide the production lift from a depth or to provide a working medium):
- 20хgsnm (20хгснм) pipe type B
- NKM pipe
- Smooth steel pipe
- NKB pipe, etc.
According to the type of welding such steel pipes are divided into:
- Steel straight seam (single seam) pipe
- Longitudinal welded steel pipe (double seam)
Various parameters and product requirements (sections, steel grades, manufacturing accuracy of ordered products) and mechanical properties, surface quality types, delivery condition will be provided depending on manufacturing method and specifications of technical documentation. Bend, hardness, flattening tests, etc. will be carried out upon additional agreement with the customer.
The price of 20xgsnm pipe rolled metal products may vary depending on the specified mandatory product requirements (accuracy, lengths, individual heat treatment mode, basic or agreed selections for chemical composition of steel, internal/external coating, chamfering, additional mechanical testing, nondestructive testing, ultrasonic inspection, etc.).
