AnCap weld soced SW ASME B16.11yn ffiting wedi'i ffugio a gynlluniwyd i selio diwedd rhedeg pibell bach o ddiaffteri -. Yn wahanol i gap weld ymunol butt -, sy'n alinio pen i ben gyda'r bibell, mae cap SW yn cynnwys soced wedi'i gysgodi. Mae'r bibell yn slipio i mewn i'r soced hon nes ei bod yn cyrraedd yr ymyl mewnol, yna caiff ei dynnu ychydig yn ôl (tua 1/16 modfedd) i ganiatáu estyniad thermol cyn i weld ffiled uno wal allanol y bibell gyda chwennol y ffiting.
Rydym yn cyflenwi pibellau, platiau, bariau crwn, a rhagamrediad cynhwysfawr o ffitio pibellau, flansys, a falfiau.Cysylltwch â ninawr am ddyfyniadau am ddim a gwybodaeth gynnyrch wedi'i phersonoli.
Daearyddiaethau Craidd a Pharamedrau Dimensiwn
I sicrhau bod modd cyfnewid llwyr rhwng gwneuthurwyr rhyngwladol, mae capiau weld socedi wedi'u peiriannegu gan ddefnyddio paramedrau dimensiwn llym. Caiff uniondeb strwythurol cap SW ei bennu gan bedair dimensiwn allweddol:
Diamedr Twll Soced
Rhaid i ddyfnder mewnol y soced ddisgwyl diamedr allanol (OD) y pibell sy'n dod i mewn gyda lleiafswm clir. Mae ffit manwl yn lleihau trallod hylif yn y cysylltiad ac yn atal amrywiadau rhy fawr yn yr bwlch weldio.
Trwch Wal Soced
Mae ffactor diogelwch ffitio wedi'i frodio yn dibynnu ar drwch ei wal. Mae safonau ASME yn categorïo ffitio weld soced i mewn i ddosbarthiadau pwysau penodolDosbarth 3000, Dosbarth 6000, a Dosbarth 9000. The minimum wall thickness (C) along the body of the cap must meet or exceed the pressure-temperature rating of the matching pipe schedule.
The socket depth dictates how far the pipe penetrates the fitting. Adequate depth ensures the joint possesses sufficient mechanical resistance against bending stresses, structural vibrations, and hydraulic shock.
The overall external length of the cap determines the spatial envelope required during system layout planning, ensuring terminal points do not interfere with structural beams, structural steel, or valve clearances.
Dimensional compliance must be paired with correct metallurgy. Forged components are selected to match the chemistry and tensile profile of the matching pipe material to prevent galvanic corrosion or thermal expansion cracking:
ASTM A105, these components provide structural reliability for standard ambient and high-temperature utility systems.
Low-Temperature Carbon Steel:ASTM A350 LF2, these fittings maintain notch toughness down to –50℃F (–45℃), making them ideal for midstream extraction environments.
ASTM A182 F316/316L, stainless grades prevent oxidation in corrosive chemical environments and resist localized pitting.
