Big diameter seamless steel line pipes for the gas line and petroleum transportation 20-50 inch API 5L

Enormous measurement consistent of the big diameter seamless steel line pipes
Big diameter seamless steel line pipes for the gas line and petroleum transportation 20-50 inch API 5L are one of the specified products of PETROL STEEL CO., LTD. APL 5L determines the assembling of two items levels (PSL 1 and PSL 2) of consistent and welded steel pipe for the utilization of a pipeline in the transportation of petrol and petroleum gas. For a material utilized in an acrid assistance application, administration to Add-on H for seaward help application. The APL 5L determination covers lines to passing on oil, gas, water in the petrol gas and water appropriations in ventures. The maker utilizes Ingots, blossoms, billets, loops or plates which are utilized for production of the line, made through essential oxygen, electric heater or open hearth in mix with cluster refining measure.
Big diameter seamless steel line pipes for the gas line and petroleum transportation 20-50 inch API 5L are characterized by; Execution: consistent lines which is utilized around 24 inches, LSAW over 24 inches, ERW up to 20 inches. Determination level: PSL1 is a standard quality utilized for pipelines. Surface completion: dark, stain painted, subterranean insect rust, electrifies. End types: plain, slanted, strung closures.

Big diameter seamless steel line pipes for the gas line and petroleum transportation 20-50 inch API 5L have a scope of preferences that the end client can profit by. They incorporate; Hydro-static tests confirmed; the Line can withstand a hydro-static test without spillage through the weld crease or the line body. Jointers need are hydro-static tried. Twist test confirmed; No breaks can happen in any bits of the test piece and no opening of the weld can happen too.

Dimensions capacity to bear API 5L consistent line.

1.For outer diameter under 50 in (1,270 mm), pipe body distance across flexibility +/ - 0.5 mm. Line end +/ - 0.5 mm; Out of Roundness ability to bear pipe body is 0.9 mm (0.036 in), pipe end 0.6 mm (0.024 mm).
2. For OD same or more than 20 in (508) to 50 in (1,270 mm), (expansiveness ability to bear) pipe body is +/ - 0.0075D, pipe end +/ - 0.005D anyway max to +/ - 1.6 mm (0.063mm); Roundness ability to bear pipe body ≤ 0.015D, pipe end ≤ 0.01D. (In case agreed with creator and client, even more cautiously protections could be applied)
3. For divider thickness SCH 20, SCH 30, SCH STD, STD 40, SCH 80; For Programming interface 5L reliable steel pipe thickness in 8 mm to 30 mm, +0.150t, - 0.125t; For Programming interface predictable line thickness 10 mm to 25mm (0.984 in), +/ - 0.125t; Divider thickness ≥ 25 mm, +3.7mm or +0.1t (if greater) and - 3.0 mm (0.120 in) or - 0.1t (if greater). t for thickness;
4. For straightness, max for full length, opposition most outrageous 0.15% of length.
5. Straightness, max deviation for pipe end, will be ≤ 0.3 mm/m.

6. Length +/ - 6,000 mm for general, +/ - 25.4 mm for novel.

Predictable creating types of Big diameter seamless steel line pipes for the gas line and petroleum transportation 20-50 inch API 5L
Programming interface 5L Consistent steel pipe creation techniques can be divided into: Hot-moved predictable line, Cold drawn (moved) line and chamber, Warm augmentation pipe, Cold turning chamber and Press tubes.
Game plan – Consistent Programming interface steel pipes are delivered utilizing a round steel billet while welded pies are created utilizing a strip which is rolled and welded. The course of action pattern of predictable lines incorporates creating, opening, rolling, and shaping all at a time. The deformations in the steel can be easily murdered during the moving cycle. Of course, the plan pattern of seamed or welded pipes remembers bending plates and welding for needed shapes. The route toward making welded pipes is more moderate, and subsequently, the expenses are lower. Regardless, with respect to execution, predictable ones are course ahead.
Hot Moved Consistent steel pipe manufacturing measure
Hot Moving Consistent Steel Line Assembling/Creation measures; Moved Round Billets – Assessment – Cut Off – Warming – Penetrating – Extension – Slight Strain Decreasing – Fixing – Corp End Cutting Off – Visual Review – NDT – Hydro-static Test – Closures Parade – Item Examination – Painting and Checking – Pressing – Warehousing
Cold Drawn (Rolled) steady steel pipe manufacturing measure
Mother pipe (Regularly for hot moved line) – Examination – Toughening – Finishes Treatment (Hitting and Penetrating opening) – Pickling – Granulating – Phosphorization (Annoit) – Cold Drawn (Rolled) – Degreasing and Cleaning – Warmth treatment (Arrangement treatment) – Fixing – Hydro-static test – Painting and Stamping – Warehousing
