Description

Thick Wall Thickness Seamless Pipe

thick wall stainless steel pipe,(manfuacturer) stainless steel pipe diameter and wall thickness is less than 20 steel tube called a thick wall steel pipe. Geological drill pipe is mainly used for oil, oil chemical industry with the cracking of pipe, boiler tube, bearing and automobile, tractor, aviation with high precision tube structure, etc


BRIEF INTRODUCTION

The biggest difference between thick wall stainless steel pipe and thin wall stainless steel pipe in steel pipe wall thickness, generally speaking, thin-walled steel pipe cold drawing technology,

And thick wall stainless steel pipe generally use hot rolling technology, if unit of measure is used to distinguish, so, it is generally believed that the wall thickness/diameter is equal to 0.05 is watershed, the thick wall pipe and thin wall steel tube wall thickness is thin wall steel tube/pipe diameter less than 0.05, is greater than thick wall steel pipe, on purpose, thin-walled steel tube used in pipeline. And thick wall steel pipe used in billet of hollow parts. Under pressure, and important use in the pipeline.(thick wall stainless steel pipe manufacturer) 


USE PURPOSE

Thick wall stainless steel tube/pipe(manufacturer) is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid transportation, water supply and drainage. For gas, gas, steam, liquefied petroleum gas. For structure: piling pipe, bridge; Dock, road, building structural tube, etc.

THE MAINTENANCE

Key for thick wall stainless steel pipe/tube(manufacturer) quality wall thickness uniformity, thick-walled steel tube wall thickness not controlled will directly affect the quality of stainless steel pipe and USES, thick-walled steel tube, large diameter thick wall stainless steel pipe generally used in all kinds of mechanical processing, thick wall parts processing, thick wall steel pipe wall uniform will directly affect the quality of the post processing parts, thick wall steel pipe wall without control, is the quality of the whole steel pipe is not strictly controlled. Choose suitable venues and warehouse storage area or warehouse, the thick wall steel pipe should be chosen in a clean, smooth drainage place, away from the factories produce harmful gases or dust. Present to remove weeds and all the stuff on the ground, keep clean thick wall steel pipe. In the warehouse shall not with acid, alkali, salt, such as cement for thick wall steel tube with corrosive materials piled up together. Different varieties of thick wall steel pipe should be piled up, to prevent confusion, to prevent contact corrosion. Large steel, steel, steel plates, shame of large diameter thick wall pipe, forgings, etc can open piled up.

Small and medium-sized steel, wire rod, steel bar, the diameter thick-walled stainless steel pipe,(manufacturer) steel wire and wire rope etc., can be in a well-ventilated heat storage material, but it must be on Shan under the mat. Some small thick wall steel pipe, steel sheet, steel belt, silicon steel sheet, small or thin wall thick wall steel pipe, all kinds of cold rolling, cold drawing thick-walled steel pipe as well as the price is high, easy to corrosion of metal products, can deposit into the Treasury. Warehouse should be selected according to the geographical conditions, generally USES ordinary closed warehouse, namely the roof walls, doors and Windows, a ventilation device warehouse. Warehouse to the attention of the sunny day ventilated, rainy days notice closed moistureproof, often keep appropriate storage environment. Reasonable stacking, the principle of advanced first put stacking requirement is under the condition of the pallet solid,thick wall stainless steel pipe/tube(manufacturer) ensure safety, do pallet according to the varieties, specifications, variety of materials to pallet, respectively, to prevent confusion and mutual corrosion, banned the crib near a store items, the role of thick wall steel pipe corrosion were principles. Outdoor stacked section, the following must be wood or stone, crib face slightly tilted, and to facilitate drainage, and pay attention to material placed flat, prevent caused by bending deformation. Stacking height, artificial homework no more than 1.2 m, mechanical work no more than 1.5 m, crib no wider than 2.5 m. between pile and pile should have certain channels, check way for o. commonly 5 m, access depending on the size and material transportation machinery, general is 1.5 ~ 2. Om. The pile bottom cushion is high, if the warehouse to the cement ground in chaoyang, higher o. 1 m; If for mud, pad high o. 2 ~ 0.5 m. If the open area, cement floor mat high o. 3 ~ 5 m o., sand and mud surface mat high 0.5 ~ o. m. 7 Angle steel and channel steel should be deposited in the open air, over the mouth down, beams should be made to put, thick wall steel pipe of the groove face up, not I to avoid water accumulation of rust.
