Oil casing is a large-diameter pipe that acts to fix the wall or bore of oil and gas oil wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock formations and prevent the wellbore from collapsing while ensuring the circulation of drilling mud to

Product name: SSAW steel pipeMaterial: Carbon steelSize: 813x9.53x6000mmStandard: API 5L/ASTM A53Quantity: 5000 tonsMany cooperations have given the customer full confidence in THREEWAY STEEL.

The construction of cement mortar fabric should usually be carried out after the spiral steel pipe is laid, the pressure test is qualified, and the soil is compacted according to the planning requirements. Due to the small rigidity and thin wall of the steel pipe, the pipeline must be in a stable st

First, safety precautions1. It is strictly forbidden to stand under the primary straight-through valve of the steam boiler pipeline drain. 2. There is no one within 1 meter in the diameter of the outlet of the drainpipe at each drain point. 3. There is no one within 50 meters of the outlet direction

Introduction of the high-frequency welding process of submerged arc steel pipe:1. Control of weld gap: After rolling by multiple rollers, the strip is sent to the welded pipe unit. The strip steel is gradually rolled up to form a circular tube blank with an opening gap, and the reduced amount of the

The wall thickness of the spiral seam submerged arc welded steel pipe is uniform and looks good, and the force is uniform and durable. A phenomenon that is easy to occur in the process of steel pipe rolling and adjustment, the uneven wall thickness of steel pipes is mainly reflected in the appearanc

Oil casing is a high-end product produced by steel pipes. There are many varieties of the casing, and there are many types and requirements of casing pipe end buttons. The button types that can be processed include STC, LC, BC, VAM, and other button types. The production and installation process of

Many things have never been seen in the materials produced by construction projects, and they must be studied and studied. Here are some points that should be paid attention to in the purchase of straight seam steel pipes.1. Purchasing needs to know the types of steel pipes:a. According to the type:

Galvanized steel pipe, commonly known as cold galvanized pipe, adopts an electroplating process, only the outer wall of the steel pipe is galvanized, and the inner wall of the steel pipe is not galvanized. The hot-dip galvanized steel pipe adopts the hot-dip galvanizing process, and the inner and ou

Duplex stainless steel pipe fittings combine the performance characteristics of 304 and austenitic stainless steel pipe fittings. This paper compares the duplex stainless steel pipe fittings with the stainless steel pipe fittings with 304 and 316L as the main material, and draws the following differ
